Rated 1 out of 5 by from Horrible Polar has found a way to make the least user friendly bike computer I have ever used in my life.

Rated 5 out of 5 by from Good product Great product I like this item, it can be a bit confusing with the buttons. I went on a ride thought I started it but did not, auto pause feature would be great. Linking the bluetooth sensors was super easy.

Rated 4 out of 5 by from Complex Device in Cyclecomputer-sized package I'm pleased with the device, purchased to replace my CS-500. I like being able to opt out of GPS use with the sensors--hopefully this will preserve the battery enough to do long rides. Set up is easy, Polar Flow useful enough.

Rated 5 out of 5 by from Love it! I bought this about a month ago and it's had steady use. I upgraded from two separate bike computer/heart rate monitors. Now I just have one device that does it all. I love the information it provides. It works flawlessly and very accurately especially with the speed and cadence sensors. Instructions are good, set up was easy, and the fact that it's firmware is upgradable keeps it future proof Note: I do not use STRAVA. I do not use PowerMeters, but the bonus for me is this is a multi-sport device. Take it hiking, skiing etc., Just make sure you get a GPS signal, and you're ready to go!

Rated 5 out of 5 by from Awesome Cyclometer ! I bought this product 2 weeks ago and i'm having a blast with it.... I had a previously model CX5 and had very good results for past 4 years with it . I might be slightly bias however, as I've always had polar products on my bike or wrist. I've seen the other brands out there, however i was never convinced of their quality, now i'm totally excited that i waited to purchase a new cyclometer. My M450 does everything i would want a cyclometer to perform..... i can store all my favorite training targets and also have my daily training schedule synced to the diary, in the event i happen to forget what my schedule is for the day without turning on my desk top or laptop computer to to sync a current schedule workout...Once i had a total grasp of ll the functions and different programs attached, it's am awesome machine. great stuff ! :)

Rated 5 out of 5 by from Worth double the cost I am going to start off by saying I have been using Polar products for over 15 years. Racing triathlons, 5Ks to 13.1 and running some of those 5Ks in my firefighting gear. I push my body beyond all limits. I can train in the zone I want to for the time I want and get the needed information to track and modify my training. Heart Rate Monitors work when training correctly. I get on the podium even when wearing my fire gear. For 199.00 you get more than your moneys worth. It is simple to install and sync with the sensors. I use both the cadence and the speed ones mounted to my chain stay. The unit itself, which scores Polar bonus points, is how easy it is to mount the detachable mount to your bike. This included band, which comes in 3 sizes, secures its. I have on occasion despite a very neat installation, cut myself on the zip tie ends. A breeze to program user information and set up your own sport zones and display screens. If training indoors in low light, which I sometimes do, you can lock the screen light on and it uses minimal power. Syncing data either with BT to my iPhone or Samsung Tablet with the FlowSync App is flawless but rather slow. Hooking it up to an iMac charges it or syncs it to FlowSync. It has all of Polar's features that are necessary to achieve your goal. I use this as a supplement to my Polar V800.
