Reviews of Polar M400 Black Heart Rate Monitor

So far so good

I have the Polar M400 "Sports Watch" for about two weeks now, it is working well to date. One little quibble with the NAME used on the advertising of the product. Why call it a Heart Rate Monitor when there isn't any chest strap & sensor included in the box. ( A bit misleading) This has necessitated my having to buy a Polar H7 HRM separately at a later date ----- extra cost to me :-( Tom

Brilliant GPS watch/activity tracker

Bought this to replace my old GPS watch (that had to be synced with a cable) AND a Fitbit flex. The watch looks great and is very comfortable to wear. The display is clear and easily read. When not in use in GPS mode it automatically tracks time spent sleeping, sitting, standing, walking and running and shows the results on a really neat app when synced by Bluetooth. The GPS is extremely accurate and I've had no problems after 300 miles. As a bonus (I didn't realise it when I bought it) it also beeps and displays texts, calls, emails, notifications from my iPhone. This function can be turned off if you wish. I need to charge it every couple of days but I don't mind this for the work it's doing and it charges really quick. Would highly recommend to anyone

Good solid running watch.

Bought this without the HRM, as I would hope to upgrade to a watch with a built in HRM in about 12months (If I keep up the running!). I have found it very accurate, and it gets a GPS signal within 15seconds (usually about 8 secs). The app is excellent, syncing up through bluetooth seamlessly. The battery is very good too. I charged it to 100% when I got it, and over 16 days I did 7 runs (about 6-8k each). The battery still had about 15% left after this. I export the data to strava (as I've always used strava), and it transfers easily. I've read that the app will be integrated with strava soon, which will be a nice addition. Overall, I am very pleased with this watch as a running watch. I haven't used it for anything else yet, but I will use it for cycling at some point. I would recommend it on price and performance.

Polar m400

Used this watch now several times, both running and cycling. Very accurate. Picked up satellites v quick. Very good product at a very competitive price. Found the personalised profiles for each activity very good and easy to set up. Highly recommend for anyone looking to get accurate GPS and heart rate analysis. Haven't used it in the pool or open water yet.

Great value and a step up from Polar loop

Having used a Polar Loop for 8 months or so to track daily activity and gym workouts, I have added the M400 to my routine. As its bulkier than the loop I just wear it when actually training with a heart strap (where it lets you easily categorise and start/stop your training log thus improving on the Loop) or tracking a walk or cycle with the GPS. It gives you feedback on your training level and has a fitness test built in. The types of training to log and the information to display are fully configurable so if like me you don't run you can remove the running options and add your own. My only complaint is that it doesn't use the very cool magnetic sync/charger connection that the Loop uses , the micro usb connector might be universal but its clumsy and slower to use than the proprietary one with the Loop.

Polar m400

Bought the watch to motivate me to do more - so far so good. I've been out every day so far and don't see me stopping. Great product. Easy to use.

Excellent

Been using this for a month now, so much better than I thought it would be for a great price. The GPS works great, as does the paired heart rate monitor. Great for cycling and have got back into swimming due to it being waterproof. Would recommend.

Highly efficient and reliable service!

This was the first time that I have used Fitness Digital. I chose them after an extensive review of similar sites both in the UK and Ireland. Their site is very easy to navigate and the prices are extremely competitive and offer a wide degree of variety to help one navigate through the possible choices. The Polar M400 that I ordered came on time to the exact conditions that they had stated in the order. I am exceptionally happy with Fitness Digital and will continue to shop with them in the future.

Good value product

The GPS and watch display while running work very well, which is why I bought it. Polar Flow is okay for recording activities, about the same as other services I've used like Nike and Strava.

reasonably priced sportster and fitness tracker

I doubted between the Polar V800, Polar M400 and Apple watch. Used previously Fenix 2 from Garmin which became a bit unpredictable with HR measuring. Based on my current needs I went for M400 as I didn't have much use for other measurements, although as I started outdoor running more actively I realised V800 could be better choice now. However I love my M400 for what it enables me as it covers my whole day, buzzing me sometimes for further activity and helps me not being overtrained from my gym sessions. Also syncing with Polar flow and further integration with Apple Health is awesome. Initial setup was easy and my passage onto new watch was without any hassles. What I don't like it's watch strap, I would definitely change it if I could, but there is no way. Based on the value to money ratio I would go for this watch again as a gym person, although for indoor running you'd need a food pod to measure distance and speed. Outdoors these measurements are taken from GPS.

Excellent budget GPS watch

Easy to use, great value. I bought this for running and it suits my needs.The only downside is the app is a bit flaky. When you're synching your training, it tends to say it failed even though it actually worked. The backlight is really handy for when it's dark. GPS locks in quickly too.

Excellent watch

Bought this watch over a fitbit having looked at reviews on line. Really pleased - watch looks good, fits under shirt sleeves and tracks activity well. Alerts you when you have been inactive for a period of time.
