We've had them for 15 years. Turned out the previous owner of our house had a contract with them…read more A few years after moving they came out to do "service" and the owner insisted that my wife sign a contract. BIG MISTAKE. Now we supposedly "lease" the equipment from them. If we want to terminate, it'll cost us dearly. I said, OK, at least they will service the equipment - WRONG AGAIN. Service guy came out said we need some of the cheapo plastic door gadgets replaced - they are now 15 years old. He told me I had to call to request this. I did, and the owner or whoever she is said, no, if they've been abused you have to pay for them. WHAT? They are just stuck to either the wall or a stationary door! How can they be abused? She said she'd get back to me. Crickets now for over a month. This company needs ethics training, although it's probably too late for them. AVOID, AVOID, AVOID!!!!!!!!
