Same for me yet.
Absolutely agree!
Ok for diving locations and conditions problems.
Proper maintenance and cleaning are the key words, for every rebreather!
The 5 more minutes needed for OPV (or whatever else) checks are not really important but they could do the difference underwater.
Beside "take your time" I don't really know what else to say!
Best,

I have 2 Boris' (OK, I have one, the missus has the other) and we've not had any serious OPV issues. I think once we've got a grain of lime in there and found it on a negative test. But between us it's never proven to be an issue when we've dive the units so far...
