I was in a hurry in the morning and did not check the reviews carefully. I thought I payed higher than average price for replacing a garage door opener, but the product I got was even not the one we talked about. I found out this after the guy left. Not mention that the whole process was very unprofessional. There is no formal receipt, no manual, no warranty card. The only thing I can do now is to cross my fingers and hope the new garage door opener work to the age it is supposed to be. I was even blamed for miscommunication. How could! I know I will never call that number again.
