With apologies in advance, I need to say that this is a common and annoying type of statement.
1. " I know someone who......" is hearsay that disconnects and insulates anyone from any responsibility for the statement.
2. The repairer is qualified to say that the subject gear is made like crap but is probably not qualified to say that it sounds like crap.
I don't want to jeopardize his business by name dropping. By all means, keep arguing amongst yourselves.
