Rated 4.5 out of 5 by 238 reviewers.
Rated 4 out of 5 by quite simple to install and works purchased this to replace an older model, this one being the exact same but updated, so same size opener made an easier install. everything was in the box except for 10 staples. I would recommend following the instructions exactly, unpacking everything first and laying everything out as the diagrams in the manual, also get all the tools you need in a handy location, it is possible to install on your own as long as you have a stepladder of a suitable height, but another person will make the process quicker, read the instructions carefully when making the adjustments and don't rush. I was able to use existing wiring and support brackets which made things easier and quicker. Unfortunately the price has just been lowered by $20 which is not good news for me. July 17, 2012
Rated 5 out of 5 by Great product and easy to install!! I am a 52 year old woman and installed this garage door opener, by myself, in one afternoon. The directions are easy to follow and the opener itself is not too heavy for one person to manage. I am VERY happy with this purchase!!! March 5, 2013
Rated 4 out of 5 by Great value Couldn't believe everything was included for the price. Would recommend having a second person to help with assembly/installation. Installing in below freezing temps presented a challenge as wires became very brittle. Definitely happy with my purchase. March 18, 2013
Rated 4 out of 5 by Solid performer Works great. I had a bit of trouble with programing the travel stops. Need to be sure and place the chain properly on the track. I had to use the customer service number and they were really great and knew the product inside and out. March 14, 2013
Rated 4 out of 5 by A super online only sale bargain.. I was looking to save a little money on a garage door opener when I found this one on a online only sale. Saving $40.00 was awesome. The company that I bought my 10' X 8' commercial grade garage door from installed my opener for me, but I would of installed it myself if the door would of been there already. And sense this was installed on a steel carport it's a little noisier than I like but hey I saved the bucks I needed and after a while you get use to the sound. The opener does just what you want it to do.A really great value for the money. Oh and free UPS shipping was the added bonus.. March 19, 2013
