Has anyone ever pried one of these open and looked at the guts?

they work great, when they run.

I have 2, one has been back once, one has been back twice, and now
neither of them are working after a power failure.

My father has similar experience with his.

Sad, they work so well, and are so poorly made.

300-500 bucks, I thik you shoul dget more than 18 months out of them.


Anyway, anyone tried fixing them? I refuse to spend 150 bucks or
whatever they are charging[I had mine fixed under warranty] every year
