If I could give less then one star I would. Chris is very dishonest. He picked up my autoclave for repair and said that it was unrepairable. I asked for a photo. Once he returned my unit unrepaired I had someone else come and look at it. It was a switch. I called CHRIS, asked him to refund my money There was a charge of $160.00 just to look at it. He won't return my emails or calls. Here are the photos.
