I had the variable voltage Sabre touch, and it's definitely not regulated. It's a good unit, don't get me wrong... but it doesn't provide a consistent vape imo.
I have had it only a short time, but seem to get the same reading on the multimeter after using it for awhile. Also I probably wouldn't notice it anyway because I run it so hot (12-14w) that a little drop of doesn't make much of a difference.
