Rated 5 out of 5 by from LiftMaster 3950 (sidewinder) I am delighted with this product. It allowed me to have the garage of my dreams. We purchased a vintage Corvette and had no place to put it, so we decided to build a custom garage. I wanted a drive through garage with vaulted ceilings, and a car storage lift to store the car up high into the vaulted ceiling. I could not do this with a regular garage door opener that pulls from the center, and the drive unit mounts hanging down from the ceiling. This would obstruct my roll up doors. I discovered LiftMaster made the 3950 door opener that operates from the side of the door, not the center. Using the 3950 there was no obstruction, and my doors could track 1 inch from vaulted ceiling. The LiftMaster 3950 made this custom garage design possible. I have these on both roll up doors and am delighted.

Rated 4 out of 5 by from Very good product but Very good product but I'm not happy with the opener remote. Many times I need to be right up close to the door for the signal to open the door . My wife has the same problem with here remote also . Do you have any suggestions . Thanks
