I have used 2 go controls on my garage door openers for like 7 years now. Work great. About 5 yrs in the tilt sensors started getting flakey. They use a small ball bearing capsule thing to sense tilt. I replaced those with small mercury tilt switches off of eBay and have been flawless since. Used initially with Abode security system, then mov d to HomeSeer.
