I purchased this in January but didn't use for a few months since I'm used to using apps on my phone for running. When I did finally use it, the band had to be taken apart to upload the information to my computer. After taking apart two times, the band would not stay together on my wrist for runs (two times!) and I sent to the company to be fixed. They sent me a bill for $60 for the repair. The warranty of 1 year on the website seems to have a lot of loopholes. The repair said the watch needed to be fixed for a water test. I didn't run in water nor did I need a water test. I needed a new band. Buy a watch that doesn't need the band taken apart to get the results. This is a crazy design which is time consuming and obviously doesn't work well. I can't speak to the results of the actual watch because I couldn't get the band to stay on.
