I had to send my first box back, the USB port had problems. Second box worked as advertised. I agree with some reviews that it would really benefit the manufacture to add a user guide. It is quite a bit smarter than one would think from reviews and advertisement. Using my I phone on the USB port when you activate it using the test button the blinking blue light indicates that it is active. The advantage of using this port is it shuts off when charging is complete on the Iphone 6 anyway. Handle works fine for moving box around boat floor and such but suggest picking up with lower box handles when transporting. I like this product.

I love this. I previously had a UP24 and I like this so much better. You don't have to take it off to shower or swim, and you don't have to tell it when you are going to sleep. It's much lighter than I expected. I wear it on my ankle because I discovered that my arms were more active than the rest of my body and didn't really give an accurate reading of my activity. The walking and running programs are awesome. I tend to slow down and this reminds you to keep your pace up. I haven't tried the biking mode yet, but I can't wait to.

I couldn’t make it a full two weeks to even see if any results occurred. I applied it on both upper and lower and I kept getting it in my eyes. It burns for several minutes and causes redness and watering. I think my biggest issue was the little brush. If it had a different type of applicator, it might have been easier to keep out of my eyes. This should come with a warning about getting it in the eyes.
