Tools and Hardware Reviews of Chamberlain LiftMaster 975LM Laser Parking AssistCustomer Review: Tennis ball works better Summary: 3 Stars
I set up the tennis-ball-on-a-string system and this one up at the same time to see which worked better. I chose this device after reading the reviews, and opting for a gadget that didn't run on batteries. The tennis ball system required me to put a screw into the garage ceiling directly above where the car's windshield is when parked, tie kite string to it, drive the car in to where I wanted it, then tie the string to the ball at the right height (I put a small screw into the tennis ball also, and tied the string to it). Total time to install: about half an hour.
Installing the lasers was complicated by the fact that I don't have a Liftmaster-brand garage door opener. Mine is an 'Access Master' (supposedly compatible with Liftmaster). I figured I'd be out less than $25 if the lasers didn't work. Each laser comes with one screw, a drywall mount, some screw nuts, and about a 5-foot long cord of low-voltage type dual-strand (one black, one white) insulated copper wire. You are expected to strip the end of the wire, then connect it up to the terminals on the opener that go to the safety sensors. Some wire strippers to take the insulation off, and some pliers to pull apart the wires would be helpful. Since I didn't have a Liftmaster, the black/white terminals weren't labeled on the opener. After a small amount of trial and error, I got the wiring sorted out. The only thing keeping the whole laser from swiveling when installed is the tightness of it's single screw. As another commenter suggested, double-sided tape or something sticky would really help. Total time to install: also about half an hour.
After aiming the laser, I could try out the whole setup. When driving into the garage, the tennis ball is in your face, right at eye level. You can see how far away it is. When you physically hit it with the windshield, it bounces. It's very obvious that you are now in far enough. No matter what angle you come into the garage, you can't miss the tennis ball.
The laser starts out as a tiny dot on the floor. I can't see it at all until it starts moving across the dashboard of my small car. The dot is small and flashes. If you drive in at different angles, the dot will be in a different place. I often don't even notice it until after I've already parked and intentionally look to see where the dot ended up. If you intentionally ignore the tennis ball, you will be driving in very slowly, stopping, looking for the dot, then driving a little more, etc.. until you see it. If the mounting is not tight, it will swivel a bit and misalign the dot. It seems to work a little better on a bigger car with a shorter dash, though you still drive slowly in stops-and-starts till you see the dot.
The tennis ball seems to be a more foolproof system. It is so simple, it can't help but be reliable and easy to use. There is no chance that it will fail due to dead batteries or a power outage, get out-of-position, or make you wonder how far away from it you are. Interestingly, when I looked for the lasers at two popular home-improvement stores, neither had it. One was selling a kit that was basically a foam ball on a string.
The laser is way cooler than the tennis ball, but if you prefer function over cool go with the tennis balls. You can also turn on your wipers when parked to give the tennis ball a whack and watch it fly all over for a bit. Take that, lasers!
