I purchased a garage door opener and it has never worked. The first time I tried the batteries fell out of it. I have had my family and friends try to fix it and they all say it is junk. It cost me 30 dollars and I have never been able to open the garage door. The # on the back is108210 0107 310 Multi code by linear FCC IDEF4MICRQ.10 CANADA RSS/CNR 210 1078-102-1577
Please send a new one that will work or refund my money.
