To be honest I was recovering from heart surgery two weeks prior. Due to the timing of the trade show, I didn't have much choice. They were close by and it saved on shipping cost, (I didn't know at the time if was something I had done.) All that said none of that was their fault. They actually walked out to the vehicle with me, inspected the machine, hauled it into the trade show, got me and the wife into the show. They explained to us what the issue was, but by that time I was hurting pretty bad, I remember it was minor, and he could tell I was hurting so rather than making me wait for them to fix it, they just gave me a new machine and sent us on our way. I have used it almost daily since then with no issues.
