Hi
Ive not been called out to 1 of these yet while they have been under warranty.
so that is good news for then them. as to reliability they are quite good.
I saw 1 of them a few weeks ago during a training course and they seem like a good strong sturdy machine. so they should be a good buy.
Hope this helps.
