I had my Polar CS100 for just over two years and experienced none of the issues described in some of the other reviews. Unfortunatley I lost it this past March after a long ride with friends. It was fairly simple to program my personal settings as well as those for the bike. I am presently in the proces of ordering a replacement unit.

I bought this CS100 in USA in 2007 I had no problems with it. But after the second battery replacement display was showing 9999. I feel that for some reason its not resetting. If it is a problem for so many people. I think polar should recall this unit & offer a replacement. Polar this is going to ruin your good name.

Have been using CS100 for 3 years. Changed battery and getting 9999 - no buttons work and the computer is now totally US. Based upon the number of complaints - its time for a class action

I am totally disappointed by this product. It worked well just for a few months. Then it started losing connection with the sensor unit or showing higher heart rate (for ex. 220/230bpm). I decide to change the battery to verify if it was a battery problem but after changing battery the display started showing "9999" and there is no way to unblock it. At the moment I am trying to contact the customer service (Italy) but it is quite a hard job. They are available just for a few hours and they do not answer to the phone!!!

Polar CS100 was purchased by an avid biker friend.
My Polar M21 worked great for 4 years then rubber protecting buttons failed while swimming.
I have been dissatisfied with the CS100.
Too much buck for the bang in this product.
At the end of the 2yr warranty but used less than a month of usage and I get the 9999 after a battery change.
Anyone have a solution or reset technique?

I bought this in the fall, tried to set it up this spring. This could be the worst product ever made. Wheel sensor has not worked at all. Some of the functions in the owners manual appear to be missing on the actual computer. Try resetting it. On second ride heart rate moniter stopped working. So no spped, no heart rate - just a fancy timer. After spending at least 8 hours with the manual and the computer, trying to get it to work as described I give up. It was one of my more memorable wastes of time. I am going to return it to the retailer (not excel, but I usually use excel).

The computer does not resume heart rate dispaly of you leave your bike for a few minutes. To get the reading going again you have to start allover, meaning all the trip log up to that point will be lost. Also the distance can only be viewed in very small fonts in " matrix" format and not on main display. If you like to glance at your computer and see how many miles you have traveled, consider buying another computer! Polar uplink v1.6 does not allow you to reprogram the main display, only the matrix. As a mountain biker, I think i made a wrong choice with this purchase.

I cannot complain about my unit. I had none of the issues described by others. I bought it near the end of last season, logged 2000 miles with it without any malfunctions and unfortunately lost it today during a training ride. I will go and buy another one without any hesitation. Maybe Polar fixed their problems for their newer models.

I have been using mine for over a year now and have had none of the problems listed above. I wanted a HR monitor/Cyclo computer that was wireless so I bought this unit. Installed in minutes. Calibrated and personalized easily. Then off I went. Very user-friendly. My only complaint is a small one, no total odometer, so I can’t see how many miles I did in a year for example. I love it and would recommend it to anyone.

I have had my Polar CS100 for a year and was very happy with the functions and accuracy until now. Sometimes it works great throughout the ride, other times the right leg of the right numerals and the beating heart icon suddenly disappear for no apparent reason. It still functions correctly and records the information properly when this occurs, but I cannot be sure if the number is a 5 or 9, or 6 or 8 because the right leg is not visible. The worst part is when I read the recorded file to enter the exercise information in my laptop I cannot be sure of the numbers to enter. Once I turn the unit off and then back on it might fix the problem, but usually I have to do a reset to correct it. Then the problem may or may not occur again on my next ride. Very frustrating. I am not going to deal with customer service again, they say send it in with a check for $75, even though it is supposedly under warranty. I am checking other brands for a replacement and will not have another Polar.

This product is a hard one to review, because it has some serious faults, but I’m actually pretty happy with it. Many reviews here mention dead transmitter batteries. Mine has been fine for two yeas now, BUT the unit definitely suffers from an issue where if the alignment isn’t perfect, it won’t recognize the speed signal. More than once I’ve had to remove it from the stem and hold it above the sensor to get it to recognize the speed, then when I put it back on the stem it’s good to go. Had it not happened to work when I first installed it I probably would have assumed the battery was dead too, because this makes absolutely no sense. The wireless sensor is also uncoded, meaning there is the potential for crosstalk if you ride with other CS users. The included HRM chest transmitter is the less conformable, uncoded T31 model (again, crosstalk). All this said, it’s gets an A+ as a HRM unit. As a bike computer it gets a B-, but having both together in one unit is,

Add me to the list. I changed the battery and the unit died. Now it just shows 9999.... it’s only 10 months old. Worked fine until I tried to change the battery. I have not tried to send it in yet but, based on these reviews, it sounds like I will be waiting a long time.

Yep, me too. Nice work Polar. I’ve used your HR monitors in the past and been disappointed...wondering if they might of fixed things with these? nope. Had this unit for about 3 weeks now and have been dealing with the unit dropping it’s speed/distance signal for every ride. Spent more time riding with this unit not responding correctly. Buy something else.

Inaccurate. Drops signal far too often. Takes far too long to pick signal up. Mileage is often off by as much as 10% to 20%. Average speed function is so far off it is useless. HR monitor function seems to work fine. This computer needs work, Polar did not have all the problems worked out. At least I still have a display, but from other reviews looks like that won’t last long.

Add me to the list of people who have had it with Polar. This new computer worked well out of the box. After two months, it started making a crackling noise and then it died. The customer service at Polar seems to consist of one guy who calls back a few days after you leave your message. They require that you pay for shipping to send back a product that should be covered entirely by them. I will now opt for an ABP computer -- anything but Polar.

I purchased a CS100 about six months ago and the cycling functions stopped working. I sent it to Polar for repairs four weeks ago and had not heard from them. I sent them an email asking about the status of the repair last week, and have not yet received a reply. Poor product, poor customer service. I would not recommend this computer.

I bought it for my wife, and it worked great for about a 500 miles, then there was a long beep and the thing crapped out, showing "8106" on the display. Changed battery and it’s still showing "8106" and won’t do anything else. Can’t enter data or anything. I wish I had seen these reviews before I bought it! (got it at Excel and have a great history of good service with them; they’re not the problem).

Add my CS100 to the list of aforementioned units that died well before its time. It is under a year old. During a ride it refused to register any data--speed, HR, distance. I thought it might have been a weak battery. Nope. I replaced the battery and the screen now reads 0170. If I press or hold any button or combination of buttons, it blinks. I feel like I’m in an episode of Lost. Not recommended. My S120 HR monitor works fine and it’s 3 years old. Polar, you are lagging. My confidence in you has been shaken. Your brand has taken a knock in my inner hierarchy of brands. Keep this up and before long Polar will be the Yugo of cycling computers.

Just like the other bad experiences... straight out of the box, the battery was dead in the main unit and the speed sensor did not work. The HR strap was functional, but, geez, for how long? The operation of the unit was ridiculously hard to figure out. How can a product be this bad? How can quality control be this poor? Don’t even bother. It looks good, but it is definitely NOT!!!!

I purchased the CS 100 computer/ heart rate monitor from Polar and was very disappointed. The wireless speed sensor would not read the wheel magnet. I called up Polar directly and tried to have them trouble shoot it for me over the phone and still they could not solve the problem. Polar told me to send it to them so they could repair it. Three weeks passed by and I called them up to find out the status and they said they still have not received the speed sensor ( Polar is in NY and I live in NY ). So I waited another week and they finally called me back and told me they would send it back repaired. So it took a month to fix the problem with the speed sensor. I personally was treated with a lot of disrespect from the Polar staff over the phone and will never buy one of there products again. I have learned my lesson and will stay with the tried and true Cateye computers which all of my 3 bicycles have.

I bought this for my wife, and the computer has been a complete disappointment. I’ve sent it back to Polar for repairs twice in the first three months. Initially the display malfunctioned. Then the unit started registering wildly inflated mileage. One suggested "fix" by Polar was for me to buy a replacement magnet from my local bike shop at my expense ($8), even though the unit was barely a month old. (Still didn’t work right, and they’ve since ignored my request for reimbursement.) Then they shipped it back to us without the chest strap, after asking me to ship everything back to them. Thus the unit has been in transit for repairs more days than its been used. I used to think Polar made high quality products and cared about their customers. I’ve since been disabused of those notions. Investigate all alternatives before spending your hard earned money on this product from this company.

I purchased the CS100 six weeks ago and I’ve already returned it for repairs. I like how it mounts to my stem. I like how it looks. I liked it until the receiver started making a sizzling/crackling sound. My dissatisfaction isn’t really with the unit, but with Polar. I called Polar and was transferred several times and each person seemed in a hurry to move me along. Then, what is most annoying, is that I had to include $2.95 so Polar can ship the repaired, 6-week old unit BACK to me. I paid Excel to ship it to me new (which is fine), then I pay nearly $4 to send it back to Polar for repair, AND I include $2.95 so Polar doesn’t have to cover the cost of shipping my 6-week old, still-under-warranty receiver back to me. Sweet deal, Polar.

I’ve been very pleased with this unit. The feature set is exceptional, giving you all of the numbers you’d expect from a high-end bike computer. I replaced my wrist-mount Polar with this computer and am very happy I did, I hadn’t even realized how distracting it was to have data readouts in two places. The mounting system is simple but solid, with a good stem-mount option included. The interface is well-thought out and simple. My only complaint is the latency with speed sensing-- it takes this guy a good five seconds to calculate your current speed, so if you take off from a dead stop you’ll glance down to see it reading "0.0mph". I’d also recommend calibrating it manually, I entered the number given in the manual for my tire size and got speed and distance readings about 10% lower then actual. Overall though the feature set is very well thought out and the quality is what you’d expect from Polar.

I recently purchased the CS100 and have had a lot of problems with the display setting. After using the Polar Uplink software I’m unable to see certain displays options (ie. average speed). Also the distance display often does not update until you cycle through the display options. (ie it gets stuck at a number and doesn’t change). The computer has all the right functions but unfortunately it doesn’t appear that Polar has worked out the bugs yet.
