What Customers Are Saying

The product appears to have mixed reviews. While some customers found the extension kit easy to install and compatible with their Genie garage door opener, others reported issues with missing or damaged parts. The kit seems to provide the necessary length for 8-foot doors, but there were concerns about a lack of transparency around the requirement for the extension. Overall, the product seems functional, but Genie could improve the customer experience by ensuring complete and undamaged shipments.

I just want to echo some of the reviews so far I buy this opener and get home put it all in and install it and it’s for a 7 foot door. I have an 8 foot door and in the fine print says I have to buy an extension kit now I’m stuck buying an extension kit and the door is Taken apart, and not operable. Yeah, not good. You’ve heard of Buyer beware Beware. Something that would eliminate this issue would be a big print right on the front of the box for 7 foot doors only if you have an 8 foot door you h...

Sloppy and unfriendly service

Would Not Recommend

I purchased this item first and waited for the garage door delivery from Lowes, that was delayed several times without anybody knowing why. So I cancelled the garage door. I tried to return this item but was declined by Lowes (online and store) for passing their time limit. It was actually Lowes that missed their delivery time limit multiple times! Now I am stuck with this item I can't use! Don't buy anything from LOWES!

Awesome addition to an earlier purchase.

This product was a must in addition to the garage door opener that I purchased some time back. Easy to install and Lowes had it at the store the time they said they would.

not happy with shady advertising

Would Not Recommend

after buying the door opener, assembly and prep for install, I discovered it's too short. The box in tiny letters says fits 7' door. So now I'm forced to return to the store and have the pleasure of spending $75 more for an extension and come home and take the opener apart to add this part. SUCKS

Perfect fit to accommodate taller garage door

Longer belt and rail were needed because we have an 8-foot door. Everything fit as it should.

Would Recommend

I am very pleased with the Genie garage door opener. The instructions were at times not clear but my installer and I figured it out. The opener is so quiet what a change in 39 years of a Genie opener! The store personnel were very helpful and courteous. I must admit I came to look but ended up buying! In summary a very nice experience!
