I just want to say that i do not consider this a quality issue.
The Provari is a
tank. I've been pretty rough on it and it still works faithfully every time. The thought of sending it away for repair makes my heart sink.... I love it so much I can't bear the thought of being without it. I wonder if I could have a new window sent to me and install it my self without disassembling the unit.
It is the best pv available imo and it's made in USA!
