I explained to the woman answering the phone that I had double thick wall board walls with metal studs. I needed someone with experience with this configuration to help me mount my TV and some shelf standards. She sent me Albert. He told me upon arrival yes he had done this before. Ok, but his stud finder couldn't find the metal studs so he had to use mine. Then he didn't have drill bits that would drill into metal, so he had to go get some. Granted he didn't charge me for his time to go get them. However, after three hours of him wailing on the wall we managed to mount the TV. Towards the end of this I asked him more thoroughly about his experience with this wall type and turns out he had never mounted into metal studs before. Therefore, not only did it take 3 times longer than it should have they also were untruthful. Would not recommend this company to anyone. Needless to say I did not ask him to do anything else.
