Bought this for a diving trip. Worked fine for that week. Put it away. Got it out for our next dive trip and the battery was dead. No problem. I’ve got replacement batteries. Nope. Tried several. Nope. Took to local dive shop. Nope. Just beeps acknowledging battery and nothing shows in the screen. Expensive one time use device. Look elsewhere for a computerThis watch came highly recommended by fellow diving friends. That said, I'm 5"3 and weigh about 120lbs, and found this watch's strap could not go small enough to fit snugly on my wrist either with no wetsuit or with a 2mm wetsuit. I think if I had been wearing heavier layers, it may have fit. I dive in fairly warm waters, and so, unfortunately, I had to return this one.Easy to see while diving and also very easy to use the one button. The only thing I did not like is that it is very BIG.I’m a beginner diver. This is easy to use and set up. I didn’t want to spend too much money starting out. This is a great watch and gives me a piece of mind.Great dive computer. Easy to use and easy to read while diving. I like the pink and white but if I were to buy it again I'd get pink and black. I think overtime the white will yellow and show dirt/use more.It is exceptional ease-of-use is the key featureThis dive computer may be easy to use, but the backlight not working, which makes it useless during a deeper dive with low light conditions. This is when the computer is most needed. USELESS to me!!! Very disappointed!Everything was as shown in the picture and it arrived on time
