Has anyone had any problems with the ultrasonic cleaners that they sell on ebay? I just bought on of them and midway through the first 380 second cycle the brass quit viberating and it has not hit a lick since !! I have a email in to the person that i bought it from on ebay but i would say that it has no warranty, since that is my luck, i guess that is what you get for trying to save money !! I will let you know what happens . Just wondering if anyone else has had any problems, the one that i bought is the same one used in the article here on the website about ultrasonic cleaning .:,
