From Tino de Rijk, winner of an X1 at Eurotek 2010:

I wrote a short review a few months ago. But so far didn’t take it diving (I am not a big cold water lover - and Holland IS cold in winter - probably like Canada).

Anyway: did 4 dives with it last week, and LOVED it. I was surprised at 4 points:
- the incredible bright screen, even at medium brightness. Not  such a big surprise, but still better than I imagined.
- the easiness of the tap-interface, even with 5 mm gloves. I was admittedly afraid for that, having had bad experiences with other brand computers with tap interfaces before - but this one simply works!
- the quality of the software, and logical, natural user interface in divemode (I use Multideco-X1). Especially switching to/from OC bailout (I’m a CCR diver) is so much easier than my previous computer.
- the size. Because it is so small, it sits nicely relatively high above my drysuit wristseals while still being very visible from the corner of my eye. The huge angle of vision certainly helps in that respect as well.

So all in all, I am a happy camper!
