I'm glad it works, but this is the exact product I thought he was trying to avoid buying. While a lot of thought and development probably went into chickenguard, it ain't cheap.
If they only lasted a year, I would have said they were a rip off. However, we've had ours 4-5 years now, I think? Only thing we've had to do is change the battery and I think twice untangle the cord that raises the door - probably because a chicken banged the door and caused a loop in the string.
