Eh, its cool when its calibrated
I got this a few years ago for a climb up Mt. Kilimanjaro and since then have used it many more times and in many different situations. Generally it's pretty cool, I have small wrists and it doesn't bug me TOO bad. But I don't really like watches to begin with so I might be biased, but I don't hold that against them my problem comes with the accuracy of the altimeter. This is the reason I got the watch and on any given climb if you compare your watch to others in your group I bet you won't find one alike which tells me its not an exact science what they have going on here. For the best results I would always recalibrate it at every camp since we were usually given the altitude and I would say generally you would be pretty close to what the actual altitude should be. One thing to remember is if you are flying somewhere to go climb this will need to be recalibrated when you land something about flying messes with it. I know that this is a common occurance with these watches which is why I don't really feel negative about the product.
I still do wear it though
