We asked the customer why there was only a single call to our tech support in the 4 years since he'd purchase our Accu-Bend Model 26 and Accu-Clinch Clincher. Here's what he said:

"Well Don, two things.

One, we are really that self sufficient that we can usually figure things out our selves.

Two, your machine has not had any major issues and really are THAT GOOD. All we need to do is keep it lubed and clean."
