My experience has been extremely negative. Did not have a chance to install their stuff yet because they keep screwing up every step of the way - missing parts, wrong parts, "parts in the mail" but missing. Rude, inconsiderate, poorly organized, and not obsenly intelligent people. How hard could it be to comprehend that "complete head gasket set is missing the head gasket"? And yet three people I spoke with (two apparently mechanics) messed the message up. Phone calls are not returned, emails sent to wrong address, and when I finally demanded an answer to a simple "where is my stuff?" question, the response was "sit and wait - we are not taking crap from you".
