These work well, but BE AWARE that your need an existing remote to copy codes from.Also, hold off attaching the back visor clip until AFTER you've done the programming.

There is nothing to like about this product. The service man from Hollywood Door couldn't make it work. It is a piece of cheap junk from China. Amazon should be ashamed of offering it to their customers. It would be nice to receive a refund.Thank you very much.Catherine Schmidt

Luck of the draw. The first remote wouldn't work. Pressing any of the two buttons would not light up the red led. So...opened up the remote...slid out the original battery from the black rubber holder...0.00v. Dead battery. Second remote worked perfectly as in the instructions. If the remote doesn't work, then check/replace the battery....CR2032. Be sure the "+" is facing up. Wonder if the seller would send me a replacement battery?

Two of the 3 worked. I was surprised that there were no pins but it did actually work. Programming was easier than using the pins.

I've been using this garage door remote for a weeks now and I'm very happy with it. It was easy to program and it works perfectly with my Marantec garage door opener.The remote is small and compact, so it's easy to carry with me in my car or on my keychain. It has two buttons, one for opening the garage door and one for closing it. The buttons are large and easy to press, even with gloves on.sThe remote has a long range, so I can open my garage door from a distance. This is especially helpful when I'm coming home with my arms full of groceries.loThe remote is also very reliable. I've never had a problem with it not working.
