Chain Drive 750 3/4 HPc Garage Door Opener w/Battery Backup - Heavy Duty - Operate your garage door when the primary power is out - Wireless Keypad Included, Model 7035-TKV,BLACK

Is good, California battery backup compliant, quiet, works with Chevy Homelink on board buttons. Delivered a day early and all the parts were there. Not too hard to put together, used it to replace a 30 year old Genie screw drive opener. Worked on a 90 degree day and it took about 7 hours with water breaks to install. Was able to reuse hangers for the existing motor mount with minimal modification, but need to put in bar end mount above door, sensors and such. I'm meticulous by nature so it probably could be done faster, with some help. This kit is nice as it's only a few bucks more than the similar units but comes with 2 remote, and a outside programmable keypad (with 'guest' number ability). Wired inside wall switch has 'lights only' button, and a lock-out button that lets door go down, but not back up via remotes (button on wall switch can still open door). My only complaint is the spool of wire that is supplied for sensors and interior wall switch is a bit meager - just enough wire for a 'perfect' (i.e. short) run to sensors and wall switch. Okay by me as I used existing wall switch wire, but be warned that if you use the long way around for sensors or wall switch you'll need another spool of wire. Oh, and don't over tighten chain - instructions indicate to tighten chain till the lazy side hangs 1/4" above bottom of rail, but fails to mention that the rail may distort before you get that much tension and fool you into over-tightening the chain. I think they assume you have the rail lying on a flat surface - I had my accross sawhorses and the lack of support allowed it to bow.

Bought this to replace my 31 year old Overhead Door unit (got my money's worth out of that!). Straightforward installation which took 3 hours, good instructions, it helped that I was able to use previous wiring. Only delay was figuring control unit mounting, but had enough parts to pull it off. It is quieter, works fine, and I'm happy to have a battery backup. Even if it needs maintenance or even replacement after a few years its a great value! UPDATE 9/6. I liked the first one so much I bought a second to replace the other garage door opener, it was an even easier install the second time. I had trouble getting the program button to work on the first unit, contacted Genie customer support, and they gave me a work around (take the cover off and press the button on the circuit board). That worked, but they went above and beyond and without prompting shipped me a new unit cover to fix the button alignment. Great customer support!

I replaced an older Genie opener with the 750, primarily because I wanted battery backup. Installation was straightforward, and the instructions are color coded, and concise. As long as you follow them point by point, you won't have a problem. The rail is slightly shorter than the one it replaced, so I had to make a an adjustment (added structural blocking in the attic), but that didn't add much time. Total time to install, including taking down the old opener and rail was approximately 3 hours. The wall console and safety beams were identical to the old opener, so I left those and all the low voltage wiring in place. My one bit of advice, if you do a similar replacement, is to note (or take a picture) of how the original was wired w/ the low voltage bits, and use that same connection setup with the new motor head. In my case, it was NOT the same as spelled out in the instructions. The previous opener had been installed by the house builders, and they apparently had their own idea about how it should be wired. However, it worked flawlessly for five years, so I just went with that wiring scheme, and the new one works flawlessly as well. I'm quite amazed by how quiet this new chain drive operates. If I didn't know better, I'd think it was a belt drive. The battery backup (main reason for the replacement) was extremely simple to install, and was still charging, so I haven't yet been able to test it, however, all the LEDs are indicating what they should, so I suspect it will work perfectly. The inclusion of an outside keypad saved me ~$35 that I was going to spend on one anyway, so take that into consideration in comparing prices, if you're thinking the same. The new 750 uses the same remotes as the older one, so I have two spares now. Programming it to sync with my vehicle's HomeLink, and an existing remote was a piece of cake. This opener *will* work with the optional Aladdin Connect, but, right now, I don't have a need to add it (I already have open/close sensors on the garage doors connected to my smart house setup). I can't speak to long term durability yet, however, if it's as issue free as its predecessor, I'll be happy. All in all, an excellent product, and I'd certainly recommend it...

My husband decided that he did not want a garage door opener after I had placed the order. As I tried to process a return for an item that has not even been taken out of the vehicle I find out that it is not returnable. I am a very loyal and quite prolific Amazon shopper. This experience may alter my loyalty.
