This model doesn’t have a lot of features but if you need a simple but reliable HRM this one does the job. It does have a few features, more than the FS-1 which is why I bought it. The more expensive units are bulky looking. This one you could actually wear as a casual watch if you wanted. I’ve never had a problem with mine and am glad I have it. I bought it to lose weight by exercsing at the right intensity and it is great for that.

I have wanted one of these for some time, but couldn’t justify the cost, but having an amazon gift cert. for Christmas helped me afford one I was wary of only one button, but it is very simple to use and is adequate enough to use all its funtions easliy. The watch is also not as large as I had expected (a good thing, since i have small wrists) and is actually somewhat attractive looking. This watch does exactly what is says and does so very acurately. It really helps you focus more on working out since it continuously monitors your heart rate and allows you to keep in your target range. I had previously always had to count beats in my head or rely on inaccurate exercise equipment readouts. The chest strap is not that much of a deal. The benifits certainly outweigh any discomfort for me. My only thing i wish this was able to do is to give a total workout time in my target range as well as total workout time, but i guess thats reserved for the more expensive versions. Dont expect alot of fancy features on this, but it will do what its supposed to do very well!
