I have been buying some parts from Mosmatic over the years and never really had any issue with them. Until now. I sold one of their swiveling cleaning head and arm that is used with pressure washers. After the customer used it for about 30 minutes, it stopped spinning. He brought it back to my shop and it didn't work on my washer either. Mosmatic said to return it to them. This was crazy on a new item. I asked them to just send a new swivel under warranty. They did and it didn't work either. So then we sent the whole thing back, along with the now extra swivel. They said it worked fine there-no problem at all. When it comes back, mind you I'm paying the freight which took all the profit, it works. Now Mosmatic is saying they can't take the other swivel back. I own it. Bottom line, they make quality parts, but have their collective head up a dark body orifice. If you buy something of theirs get it through a distributor that will warranty it. But don't call me.
