Comments about Mares Nemo Apneist Wrist Computer:

This is a very nice computer. The switch to your nitrox blend takes a bit to get used to but once you figure it our it is quite reliable and not overly conservative. I upgraded to this version because the PC upload was 'foolproof' and worked like a dream - NOT! Maybe it is my platform of Windows 7, and previously Vista, but I have never been able to get it to download a single dive. The battery life is so-so. Maybe 18 months. It caved on me on a dive trip and the dive shop in Nassau woudn't touch it, and nether would my dive shop back home. I'm still waiting to get it back and see the bill. The concept of owner replaceable has some merit. Overall it is still a good dive computer, but understand what you are getting.
