Last September I sent two units to pinvan for repairs. One is still working, the other failed twice after about a month each time. Now it has failed for the third time after five months, so I'm beginning to doubt if repairing these things is worth the trouble. Even though they repaired it twice at no charge, the freight cost and the time spent running back and forth when these things fail leads me to believe that when one fails I would be just as well off to junk it and buy a new one. I'm just curious as to how others may have fared with repairs on these units.
