Finally got Boris (nice nickname though).
I just and only dived it for around 10 hours and I need a couple of days to write something more. However the first and abosultly personal impression is: don't waist time with something else...
My first concern was about maintenance: absolutly easy.
Just refill the canister and go (well, almost).
The canister is so good that when I opened it to change the sofnolime it was dry!!
The canister design is great: CE tested for 3,5 hrs but no many problem for up to 5 with Sofnolime Grade 797.
The main electronic also show a canister temp graph, just to get an idea on how is working (not something you have to rely on).
The electronic in general is really easy to undertand, especially if the user already know the VR3. Good the passive PO2 monitor and it is possible to dive the unit just with the HUD.
They don't build in a bailout system such a regulator, so you MUST always take a separated tank with.
Oh, I can't forget the course, made with Phil Short, really really a good instructor, thanks to him.
Ok, for the moment let me try to quiet down my girlfriend, she's pretty upset because I didn't have time for here in the last 10 days...
I told her: if Boris will learn to do homeworks she will have to leave...
