my V3 works great, blows clouds of vapor. i sleep better when i am redundit, ie; i need a back-up to my back-up, to my S pass-=thruback-up. i had working 2 x V1 blowing clouds, 1 x V3 blowing clouds, and the original PS pass-thru " big thick black cord" blowing clouds.
V3 is lonely now, guess i have 3 options. try to fix them myself, try to find a good PV mechanic "lol" , or buy new.
i'm not sleeping well lately
