Yeah, we have used them extensively as well. Our business is exhibit and tradeshow, so the deadlines are very aggressive and sometimes the requests are non-standard. We had some thick clear acrylic letters cut and they set the laser start point on cutline of the interior profile instead of using a lead in. Burnt a line into the edge and required a lot of secondary finishing. I felt like that was a very amateur mistake and would not have expected that. Then we had 2-3 projects in close succession that were shipped delayed and one with a missing letter. Very impersonal account management, no one has answers, they need to talk to the factory, etc. In fairness, if we had longer lead times, I don't think there would be as many challenges.
