I had a TCI witch was pretty but not the best converter IMO. I have a Fuddle now witch seems pretty good. The only bad part of the fuddle is #1 john is slow to make and ship, #2 was a real dick in a email after I called and spoke to a ladie there asking for a tracking number almost 4 weeks after I payed and was told it would be built and shipped in 3-4 days. #3 It looked like he sent me a used converter pulled from a junk yard. Sounds like a horror story but in the end and how ugly the converter is, It out performs my TCI and locks up right at 2700 and I can tow a 5th wheel if I like. I give the converter a 9/10, Customer service 3/10
