Well, we got our 5th buffer delivered, problems with the sticking button on a few machines and then a rhythmic noise in the machine when it was working, with a load. Nobles was good to replace due to related problems.
Something about a squeaky wheel comes to mind…in any event Big John and their supplier worked well to solve or problem, withno major glitches.
Only one issue left which they will not resolve, since I am not going to complain. the plastic buffer driver pad they provide free is worthless. Take the red brristle pad any day over it. Have it as a spare if required.
