Called them on a Wednesday when our garage wasn't opening. The chain was hanging a little and center beam seemed warped a little. Because I live in South Phoenix where they are located, they arrived to my house within an hour of calling. Gabriel showed up and was very nice and professional. He explained to me what was wrong, and quoted me a very good price without trying to up sell me. He also lubed and tuned up track /wheels etc, free of charge. Plus the parts he had to replace cane with a 1 year warranty that I wasn't even expecting. He was done within 30 minutes and our garage works again (and is more quiet now). Thanks Gabriel!! I'd definitely use him again.
