We bought a house last year and it has electric gates at the entrance (name is faac). Since we moved in we have had them fixed three times, so once every three months or so. First there were problems with the buzzer, then they kept bouncing and not shutting, then they wouldn't shut at all. Each time it has got more expensive to fix...today it was £200 for call out and small replacement part. Is this normal? Need them as we are on a busy road and have three little ones...but are they just a money pit and do you need to service very regularly? Thanks
