Great Service
Great product

Works great
Works great. I had to get a longer 50ft cable for it as the one in the box is too short (40ft I think). The instructions could be a little more clear. It's hard to distinguish the parts in the pamphlet image as it's just a black and white photo copy but once you figure out the terminology of the parts and how to do the spring installation, it's really pretty simple. I'll order it again.
