Yes, I know for a fact Exactly what I am talking about John, and please, do not ever again say to me I do not know what I am talking about, that is just rude and uncalled for. You have no idea what you think I dont know what I am talking about because I never explained the issues I had. I had nothing but issues with the VL brush, it spent more time not working then it did working, the customer service was just as bad as the A/B, horrid is a word I would use, lets put it this way John my cheap $20 Harbor Freight A/B I was using at the time worked better than the VL brush, it, the HF brush never broke, or stopped working, I cant say that for what was a $100 A/B at the time.
