Well it had to happen to someone. I knew with my luck it would be me. Using the ULTIMATE DETAILING MACHINE UDM. I noticed the speeds were jumping up and down. I said hey the is neat, a variable speed UDM. then it slowed and with one last breath she dies!!! Remeber I had compaints about the switch and the mfg not notifying anyone. But I always said I love the machine. Well its been four hours since I called, emailed and tried everything I know to get a hold to some one for me to send it back for repair or replacement. NO SUCH LUCK. I can't get anyone to reply to me on how to return it. So add to the switch, poor customer service!!! If things change I will let everyone know. Think hard before buying the UDM. Another bad deal.
