I ordered from HTG 3 weeks ago. For the most part everything looked great. The one thing that got me wondering though, was the reflector. In the directions it said to be sure to "remove the plastic protecting the reflective surface"... guess what wasn't there? The protective plastic. Oh, and guess what was scratched? The reflective surface. It wasn't too bad so I didn't make a fuss about it but it did make me uneasy.
Seeing that HTG has a huge share of the internet market, and a fairly good reputation, I'm sure they'd go out of their way to fix any problems (though your fix looked less than correct).
If I was in your shoes, I'd probably do the same thing. Either demand correction at their cost or keep it all. Either way its hard to call yourself screwed.
PS - Stop hating when people try and warn you about bad service. remember these people are trying to do YOU a favor... most of the time.
