CUSTOMER REVIEWS:
Reliable!
- “Will work without power.Love that it comes with the battery. Usually that sort of accessory is an option, with an upcharge.” – ARAT
No. 8550 Elite Series with DC Battery Backup
- “We had three of these openers installed on W 8/20/14 as the gears on our prior chain driven models were wearing out at 15 years old. The new LiftMasters are much quieter and operate very smoothly. I like the automatic lights-on with motion in the garage feature. I also like the outside remote keypad for which the “Enter” button only (no code required) need be depressed when wanting to close the door. I like these openers a lot!” – GregG
The Best!
- “Very quiet and battery back up. So far not a problem very quiet it been almost a year.” – Bryan
Great Opener
- “Quiet, reliable, my q is a plus, battery backup. I’ve had this opener for about a year and have been pleased with it. It’s very quiet and reliable. The battery backup I haven’t needed yet but I did test it and it worked great. The MyQ wireless opener sold separately works well too. I had it professionally installed so I can’t say how easy or hard it is to install but it only took about an hour for them to do it.” – glock1963
Best Garage door motor ever!
- “It was a great price and has great features. And is so quiet.” – FLHR
Really Like It!
- “Just had the Liftmaster 8550 installed, replacing a 13 year old one that had a cracked gear. I really like how quiet the Liftmaster is and the technology that comes with it. I am especially pleased that they are sending me the Repeater Kit for free. I pay only the shipping of $7.00. My 2012 KIA Soul qualified for this. Thanks Liftmaster.” – Georgetown
Best money I’ve spent on the garage…
- “I previously owned an Overhead Door opener and it was chain driven. It was very noisy when coming home at 4am from work and always woke the family up. My new Liftmaster 8550 is VERY quiet and the internet gateway is an awesome feature. LiftMaster definitely hit a home-run with this cool feature. I really like all of the capabilities of the 8550 and can’t wait to use them! Huge kudos to “Fletcher” with Windsor Door for the install. He was very professional and informative about all of the new features. GREAT SERVICE!” – Anthony
