Awesome installation, reasonable price. Only a fool wouldn't be pleased with Nicks abilities and knowledge.

I'm a retired Commercial Aircraft Technician, licensed on 5 Continents for aircraft inspection and release for international flights. I know ability when I see it, as well as dedication and satisfaction gained from doing a good job. Stay with it Nick, you'll make a lot of folks happy. A job well done.
