4.0 out of 5 stars The M4 Heart Rate Monitor by Suunto 14 Dec 2010
This is the my first Heart Rate Monitor and as the M4 is relatively new with few reviews I took a chance on it. I have used it now almost daily for three weeks at the gym. The wrist watch is rather bulky and thick but comfortable and with large numerals. Yes it is also a watch, something Suunto does not push in its advertisements. I find myself wearing it to bed, the only watch I have ever done so, and with a press of a button it lights up and I can make out the time without my glasses.
I do not use the fancy exercise modes, calories burned, or the fitness test so I cannot comment on these. I doubt the calories burned has any accuracy to it but it might make you feel better about yourself. I bought this HR Monitor for just that to accurately give a me a moment to moment account of my heart rate when I exercise. Being recently diagnosed with exercise induced atrial fibrillation I have to be careful to keep my heart rate below my usual threshold of 140 beats per minute. For this the watch performs flawlessly. I actually watched on the monitor as I had a 10 second run of atrial fib with a rapid ventricular response. I stopped exercising and my heart rate suddenly dropped 40 beats per minute. In three weeks I have learned what my limits are and can usually keep my rate between 100 and 130 and have adjusted my exercise routine accordingly.
The M4 is not cheap but the quality is well worth it. The chest belt is very comfortable. I strongly suggest you go to the Suunto website and review the "how to" movie "before you try to use the watch" as this was a time saver. The Suunto "Quick Guide" paper you get with the watch is cryptic. No need to wet the contacts on the belt. Put it on and in two minutes your normal sweat will provide the moisture and you can then press the button to pickup your heart rate. A very good product!!!

4.0 out of 5 stars Sunnto M4 8 Feb 2011
I acquired this training watch for specific reasons, like biking and gym. I think it is a very good choice for someone who doesn't need and want to spend a lot of money, but wants to get the job done. It is user friendly, has free training, suggested training for wight lose and for gaining physical endurance. Easy to change the battery (done by the user not by the Suunto company as e.g. dive computers). It is rather pretty as a watch and it gives you a lot of info. If you are not very demanding in what you want (as I am), M4 is one of the best choices you can make.

4.0 out of 5 stars Calorie count more accurate than others 28 Dec 2010
Simple HRM that provides you with added motivation by reminding you of your progress over 7 days and 4 weeks. Some of the Garmin HRM work out your calorie burn from speed which is'nt good if you are cycling downhill. I'm not too sure of the calculation that Suuntu uses but would'nt buy anything again that used speed in the calculation. Each day it provides you with a target time at which you should maintain your heart rate at e.g 35min at 129-145 or 45min at 120-130 the exact level based on the your resting heart rate that you enter along with your weight and height. The negative is that you can cheat. The time starts counting 2min after starting your exercise but if you go from a resting heart rate it may take more than 2min to get upto the target rate. I have'nt used it with the Movestick that gives you added feedback so can't comment on this but its on my shopping list as I'm impressed by Suuntu.

3.0 out of 5 stars Missing some simple luxuries 8 Dec 2011
Hmmm great as a heart rate monitor but usability isn't the greatest. Really missing a simple stop watch function as when you press stop, it immediately asks if you want to continue or not, which means you can't see what time you've stopped on! Then you have to trawl through the stats before you get back to the main screen. If it's just a heart rate monitor you want, then this is fine. If you want something with user-friendly funtionality and a decent stop watch, look elsewhere!!

2.0 out of 5 stars Review from a fitness expert... 27 April 2014
Verified Purchase
I have used heart rate monitor watches for 15 years now. My last one was a Polar. This watch which is quite expensive for what you actually get looks & feels low end & cheap. Watch buttons are stiff. Non-intuitive layout. Difficult to change settings. Would have liked to have sent it back for a refund.

4.0 out of 5 stars Not perfect, but good value for the money 13 Jan 2013
By Andy
Verified Purchase
I trawled through the lots of similar heart rate monitor watches before I chose this as I wanted a watch I could wear day to day as well as a sports watch. I didn't want the watch to scream "look at me". The M4 fits the bill well. It's a good looking watch which is comfortable and has a sturdy feel. The only down side of the looks is that every day the screen shows the message "Exercise Day" until I press a button. Sorry, I chose when to exercise, not the watch.
This watch is not perfect. The Suunto staff should pick up an iPhone to learn a thing or two about ease of use. The user manual that came with it was useless, but the online version was much more detailed and was necessary before I could use the heart rate functions. The heart-rate monitor seems to work fine for me whilst running and cycling. I've only had it 3 weeks so durability can't be commented on.
