M450 is rated 4.1429 out of 5 by 7.
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.

Rated 4 out of 5 by from Could use some updates Overall happy with the product. Just wish it could interface with Strava.

Rated 5 out of 5 by from Polar in General Polar is one of if not the Nicest Company going. I have used their SX 625 until the bands are wore out, but it is still a hard piece of equipment to Beat. Simple to Operate and Easy to Read. Merry Christmas Polar, and thanks for all your assistance through the years, and hopefully many, many More.

Rated 4 out of 5 by from Could be fantastic with firmware/software updates I have had the Polar CS600 for many years and love pretty much all features. I also have bought the Polar Look keo Power pedals and love the easy integration of it and the power data I can use for training purposes. However, the cs600 did not provide certain features during the ride on its screen that I was looking for, such as average power or average lap power. The M450 seems to change this and I am thrilled with the ability to see all kinds of data analysis on the screen. I also like the ability to customize each screen which there are plenty of to my liking without constraints as they were on the CS600, though the individual views having a limit of 4 data field could probably be enhanced to 6. I have to say that its a terrific bike computer at a good price. However, as others have stated it could be far better with a few firmware software updates primarily relating to the Polar flow which to me is rudimentary to say the least compared to the Polar Pro trainer software. So here for the Polar engineers a list of items to incorporate which I have not yet found in the Flow app vs Pro Trainer or the old polarpersonaltrainer.com for post ride review of the recorded data. ability to edit/delete laps ability to see incline/decline ability to see ascent/descent ability to see MAX/MIN Altitutde ability to see temperature max/min post ride. this applies to the flow as well as the data on the M450 in laps ability to see the average gradient in flow post ride for. for example when I took the lap for a climb i would like to know post ride what the average gradient was for that lap which right now is nowhere shown. this is one of the great features in Polar Pro trainer. Same applies for VAM which is only visible during the ride. ability to analyze laps with more date such as VAM,average gradient, etc as in PolarProtrainer. I would also like to see a feature where in Flow I can select a date range with totals displayed. Currently I can only see up to a month but I would like to have the same features as they already exist in Polarpersonaltrainer where one can customize the range. Also It would be nice to have a list view on top of the calendar view and be able to name the excercises a feature already in Polarpersonaltrainer. I am pleased about the improvements in the hopes that the shortfalls will be fixed shortly. Especially since I had to pay another $200 to upgrade my pedals to the compatible version with bluetooth. (of course it would be nice if this weren't necessary) I hope that the guys at Polar will incorporate these things or provide the ability to import the data to the ProTrainer software which is beyond excellent or better yet create a web version of Polarpersonaltrainer. As others have stated all this or at least mayor parts of it can and will probably be fixed in upcoming software/firmware updates in which case it would be a 5star unit by far. I hope that it will happen rather sooner then later. thanks

Rated 4 out of 5 by from Excellent Biking Computer I bought the M450 to supplement my V800. When biking I wanted a computer that was larger and easier to read and that mounted on my handlebars. Especially now that it's getting cold, my V800 was hidden by my sleeve, which made it inconvenient to monitor my heart rate as closely as I wanted. I'm in the middle of a HIIT training program. It quickly synced with my heart rate, cadence and speed sensors on both bikes, tracks my position via GPS etc. So it's pretty much exactly what I needed. The only reason I gave it a 4 instead of a 5 is that the training load from the M450 doesn't add to the load from my V800 which I wear for my other training - swimming, cross fit, etc. As soon as they get the software updated then it will be exactly what I hoped for.

Rated 3 out of 5 by from Could be great with firmware/software updates I bought it when it first came out, and I have been happy for the most part. Apparently it records temperature, but that is not something they advertised as it doing at all. And the only place one can see the temperature history information is on the polar flow website when analyzing the plots of data for a ride. The temperature does not seem to export correctly in the .tcx file? Or at least it doesn't load correctly in Strava. Some of the visible data fields for displaying on the screens of the device during a workout are confusing, sound redundant, or just aren't clearly explained (more specifically when it comes to current lap vs last lap average values and the like). There seems to be some minor problems with the M450 integration into polar flow web app software. Syncing ride data with a phone via bluetooth seems to take quite a long time, which would not really be a problem, except that if your phone goes to sleep (or screen turns off) while syncing, it loses connection and you have to start syncing over again, so you have to monitor it until it is done. Seems like they could update the mobile app software to force the phone to keep the screen on during a syncing process so that this isn't an annoyance. The auto-pause feature on the M450 seems a little bit buggy. I'm not sure exactly what is causing it, but sometimes I'll come to a quicker stop, and it won't detect that I've stopped until I start moving and cross the speed threshold I've set for the auto-pause feature, and then it automatically unpauses as well simultaneously. The point being that it requires me to fiddle with it to make sure that it is not in pause mode or something when I am riding, and I have to think about it when I come to a stop, which defeats the purpose of having auto-pause in the first place. (Note that all of the things that I am complaining about are all things that could be fixed with some simple software/firmware updates). It seems that if you connect a speed/cadence sensor, that it uses the speed sensor solely for your current speed, while completely ignoring GPS information, because if I lift up the rear wheel and spin it, the computer will tell me that I am traveling a certain speed, when in fact I am not actually moving. It seems like the data from the speed sensor should be incorporated into a computed solution for speed based on the both the GPS data and wheel speed. It might be to much to ask for or expect, seeing as how it doesn't have turn by turn navigation stuff, but it doesn't seem like it should be impossible to include some sort of basic "race my ghost" features where the user can upload .tcx file for a Strava segment training ride or something, and then it could use your geolocation to determine when you have crossed the start point of the segment and give you some sort of indication as to your time, distance, speed or whatever compared to the ghost. Other bike computers have supported this for a while, and it is commonly known as "virtual partner". It provides elevation and tells the user how much distance left to the end and how far behind or in front of the virtual partner he/she is. This sure would be great to have!!! Along these lines, it would be nice to be able to view or select training courses on the device. It has options on the device for "Favorites", but apparently what this is referring to is "favorite training goals", i.e. distance traveled, calories burned, and time ridden type of things, but favorite courses that you set in the polar flow web app won't be synced with your M450 device. Also, even though the website says that it supports "Recovery Status" features that some of the other Polar products (V800) have, it isn't actually supported yet for the M450. If you try to see the "Recovery Status" on the Polar Flow website, it will tell you "Polar M450 training sessions aren't yet cumulating to Recovery status. Check polar.com/updates regularly to see when Recovery status will be available for M450." This is a little bit annoying. They should have included this with the "Coming Soon" features along with the promised Strava integration. Based on DCRainmaker's initial review of the M450 back in June of 2015, I was quite excited to get my hands on this device. Before getting the device I was in the group of people that use my phone as my cycling computer and then have Bluetooth enabled heart rate sensor and cadence/speed sensor for recording the data on the phone. I used either Cyclemeter, wahoo fitness app, or strava app and I quite enjoyed the functionality that was provided with the likes of Cyclemeter, but I was getting tired of not being able to see the screen well during a sunny day on the bike, having to deal with sub-par phone mounts (or spending way to much money on a mount), not having a weather (water) resistant solution, and having my phone die before the end of 70+ mile ride. This being the first option on the market for a dedicated cycle computer with full support for bluetooth, I had high expectations, and thrilled that I could finally get something that is compatible with the suite of sensors I already posses. For how much I paid for the M450, I have to say that I am pleased with it's performance, and it is much better than the phone solution I was using before. However, until some of these quirks are worked out, and Strava exports from the polar flow app in addition to "Recovery Status" is finally supported, I can't give it 5 stars. I will currently give it a 3 star due to the awesome heartrate analysis tools and fitness tests that come along with the device. Would I recommend this over other bike computers or the like at this point? It depends on if the person already has a suite of Bluetooth sensors they use. If that is the case, and they just want to ditch the phone, I would totally recommend this. If some of these issues I've mentioned ever get worked out or features get implemented, then I would recommend the M450 to everyone regardless.

This being the first option on the market for a dedicated cycle computer with full support for bluetooth (I'm ignoring the Wahoo reflkt here since it is not a true solution, and still relies on a phone), I had high expectations, and thrilled that I could finally get something that is compatible with the suite of sensors I already posses (unlike Garmin and it's ant+ support).

Would I recommend this over a Garmin 500 or the like at this point? It depends on if the person already has a suite of Bluetooth sensors they use. If they have no Bluetooth sensors, I would probably recommend that they just jump head first into the Garmin experience. But, if they have some Bluetooth sensors, and just want to ditch the phone, I would totally recommend this. If some of these issues I've mentioned ever get worked out or features get implemented, then I would recommend the M450 to everyone regardless.
