Rated 5 out of 5 by from Awesosme device! I've been a Polar customer for years. I was using the S725X Carbon Watch with Cadence and Speed. Had 2 full set-ups for my bikes. Upgraded to a new bike and the Carbon was too much for the signal (I'm on a 62cm frame). Decided to buy the M450 after both Polar, and Garmin. In the end the features of the M450 and price are PERFECT for me. The unit is small, easy to read and use, Buttons are a tad small for my bigger fingers but once I got used to it perfect! The software seems really robust. I love the GPS tracking and "Replay". It is very cool to see the route play back with music and images of the ride (well Google map images of the location). For me the "Social" experience is not needed, nor the live maps. I want data on my Heart, Cadence, and Speed. All the other stuff is too much fluff, so this product nails the above basics! GREAT JOB POLAR, and yes if you are reading this, BUY IT!

Rated 2 out of 5 by from 5 stars for the monitor!!!, 0 stars for Flow... The M450 monitor is awesome. This is my 6th Polar HRM over about a 20 year span and by far my favorite. I was completely satisfied with the CS600X until the IrDB USB stopped working with Windows 10 and had to upgrade. First session out with M450 and it's hands down my favorite Polar HRM ever. However... connecting to a computer with the provided USB cable or through the Flow app is absolutely unreliable. Polar's solution is send the monitor in on warranty for evaluation. Ok, great, but I don't have an HRM for training that will upload data. As Polar's monitors have gotten better, it seems that their data upload functions have gotten worse. The old IR transfer was almost fool proof. Then along came (and went) the IrDB which was flaky, and now Flow... Come on Polar, if your data transfer is unreliable, then it doesn't matter if you make a great monitor.

Rated 5 out of 5 by from Home Run Just took my M450 on its first ride. What a difference! Was able to track my effort with max heart rate percentage indicator and kept my cadence efficient by keeping in my target zone. Tons of great information and super easy to move through the screens while riding. Great, easy to read display and everything in the right place. Night and day between my Polar and my old Garmin. Thanks Polar. You guys knocked this one out of the park!

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.
