Buy Polar CS300 Computer / Heart Rate Monitor from Chain Reaction Cycles, the worlds largest online bicycle store.

Rated 3.4 out of 5 by 10 reviewers.
Rated 5 out of 5 by Great all around. Got this for cycling and doing cardio and am very satisfied. Purchased it with additional cadence sensor, and it really helped me to get into right tempo - after a year of use I no longer need to look at the display to know my cadence, give or take 10 rpm. Mounts easily, wireless sensors help a lot. Never looses signal after installed right. True cycling computers do have larger screens so if it is a dealbreaker for you - look elsewhere; I`m fine with this one though. 23 May 2012
Rated 2 out of 5 by Disappointed I got this item two weeks ago, and the glass is already scratched!! , the speed sensor will no work unless the watch is clamp to the bike and maximum 50cm from the sensor ( no great..), the plastic adaptor for the bike is really bad !, it does not clip to the handle bar and is too big, also it loss the frequency very often with the speed sensor and the hart rage monitor, all and all, I give 2 stars only to this polar watch, it's OK for fitness but not for cycling!!!! you are better off buying the CS200 that is clamp to the bike if your main intention is to use it for cycling. If I could I would return it and get the CS200, I don't know if the glass on the cs200 would be any better but I would hope so. I own a CATEYE Velo5 for years and the glass is intact !! this product is not worth the money at all. 20 May 2012
Rated 2 out of 5 by ok computer got this watch for about 2 months ago, has had ploblemer with heart rate and cadence sensor. when i was out and bikes right after I got it so it said that I Biking in 104 kph but I bikes for about 45 kph. pulse stops sometimes. not so good computer 07 April 2012
Rated 3 out of 5 by ok computer Sometimes when I cycle pulse comes out and once when I rode bikes with the I in 104 kph and a heart rate of 38 I actually rode for about 40 kph and my resting heart rate is about 60 but I'm pretty satisfied. 07 April 2012
Rated 1 out of 5 by Don't Bother- Get something else I bought this watch and the speed sensor only lasted 1 ride. I then got in touch with Polar and I received no response from them regarding the problems I have had with it. Even the Heart rate monitor does not work now. Get something else!! 20 March 2012
Rated 4 out of 5 by Great I love this HRM. I have had it for over a year now and up until recently haven't had one single problem. It has everything you need for both gym training and outdoors. The only issue I have is not being able to see my display when I am riding at night, the light actually makes it more difficult to see the display (when you are riding under lights). Otherwise a fantastic purchase! 09 November 2011
Rated 2 out of 5 by CS 300 This is just a piece of bling bling... its work well when its new then u got to findle with your magnet then the sensor .. it has never been somethign you can count on with. to add whenever u want to change the battery.. its dead. i think its owuld be much wiser to invest in something that would give you for yur investment. we are 3 riders and out of 3 only one is OK with his polar cs 300. mine and my other freind in dead, or the screen fade out in the rain. we live in a tropical island and it sure do rain. either u pack it in a tupperware whihc will protect it. I even had silicon on the back cover to protect it. the bottom line save your 200quid and get a Garmin, whihc i will try to do. not to mention the interferance problem... oh gosh. when new its a jewel. 20 June 2011
Rated 5 out of 5 by Good stuff. This is first heart monitor I own, and so far I`m 100% satisfied. I use it both with my road bike ( I purchased cadence sensor with it ) and on ski machine at home. Sensor signals are very reliable. One negative is the sound communication protocol, but I have spent about a hour to figure right settings for me and since then its been reliable. All-in-all great combo for the price. 05 May 2011
