Back in August 2007 I purchased a "rebuilt" TD IP from Prothe on eBay. I installed it on my newly rebuilt 1.6L engine. It worked for about 2 minutes, then started to rev uncontrollably. I was able to shut it down before the engine self-destructed. I returned the IP (my dime) expecting a full refund. After two weeks, I still had not received a refund. I sent several emails that were ignored. Needless to say, I was furious. Any reputable parts dealer would have been falling over themselves to make it right or at least communicate promptly; Prothe did neither. Thank goodness for eBay and their policies. Not 5 minutes after I filed a complaint with eBay, I had my refund. So he was watching, and had obviously received my emails requesting a refund but chose to ignore them. It was at that point that I decided never to do business with this man again. Of course, with all the aliases and websites, it's hard not to run across his web pages while searching the web for various parts.
