I had new garage doors operators installed in December. The service man called to let me know he was on the way, arrived on time and quickly and efficiently changed one door operator and had working in about an hour (new LiftMaster 8550w). I then decided to change a second door operator a week later and it was installed and worked well. I just had a problem with one of the operators not closing properly because it was sensing an obstruction even though there was none. It turned out to be a loose wire on one of the sensors. Even though it was just beyond the 3 month warranty for labor the service man did not charge for the call. I saw some negative reviews of this company but I had not had any problems with them and they have responded quickly to my call (the next day) and service people are efficient and courteous.
