I've had 5 box failures, all new box's. 3 of which were repaired more than twice, 1 box 3 times. All have failed.
Of all the box's I have purchased, only one remains working. It's on my Dakota now.
It blows me away to see freinds of mine running box's near 20 years old.
Now that I think about it, if I was there only customer, they'd be outta biz.
