I really like the fuctions of the watch, easy to use and plenty of options. The one complaint I have is the GPS unit. It doesn't work half the time. I could be out on a country road and it goes out on me. Why, I have no idea. Also, when I place the arm strap through it, the backing of the unit came apart, so I had to go to the belt holder. I wear a fuel belt so it wasn't that big of deal, when it worked of course. I have bought Timex watches in the past and never had a problem with their products, but this one is junk.
