Rated 5 out of 5 by from Great product - no surprise. I've been using Polar heart monitors since the mid 80's and didn't give it a second thought when it was time to upgrade. The 450 has not disappointed. Pairing with Polar Flow has added another dimension to my training. It's easy to use, perfect size display, and rugged. Nice work Polar.

Rated 3 out of 5 by from OK paid extra for a black "cover" which was just a backplate leaving the face white. they should be clear and mention the "cover" is NOT FOR THE FRONT OF THE DEVICE. i really wanted the top/front to bet black. Websters Definition of Cover Cover:: to place or set a cover or covering over <cover the pot> to spread over <snow covered the hills> one would come to the logical conclusion is that the "cover" would go over the TOP of the device. shewd selling tactics like this have become the norm for retailers trying to squeeze every penny of profit for their shareholders with not a care for the customer. so beware the "cover" is not what you'd think it is.

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.
