I have my automatic gate installed for the last 10 years with no problem. Mine is a sliding gate though. Changed it when I first moved in and have not caused me any problems. But it may also be due to the maintenance contract I have, they send men to maintain it regularly so it doesn't break down although its quite old. Got it from Rahardja Engineering & Construction. Did a search and this should be them: http://autogate.kellyscentral.com/about-us/
