Love having this opener. It works well, easy to install and so convenient to use.

Works with my Chamberlin garage door as it should. Easy to setup but I could do without the beeping.

Good, solid keypad. Like that it beeps when pressing buttons. Original one did not do that so this is much easier to use. Better buttons as well. Good price as well. One drawback (minor) - need to enter the code when closing. That was not required of the original.

Original failed, purchased this one to replace. Took about 5 minutes to install. Works perfect, very pleased.

While physically it looks the same there are a few differences. The back-lighting on factory one was an off-white and lit up thru the button while the this one has a red light that surrounds the button. The factory unit didn't "beep" with each key entry and this one does, which is a bit annoying. The only ofther feature that this is lacking from the factory keypad is the ability to close from an open state with only using the "enter" button. That feature was nice as only one button had to be pressed to close it when leaving for a walk or to close it while cutting grass.
