I'm not sure why some people are having difficulty with this product, but I have personally not experienced any problems with this model. Maybe I'm used to the quality of these products since I had a similar keyless entry system on my old garage opener. The item is secure on the side of our garage and has worked from day one without any problems. We have had this system for a year and it's doing fine.

5.0 out of 5 stars Easy to: Install, Program, and Use, January 16, 2009

Super easy to sync with system.
Very easy to install (mounted on wood trim of a vynl sidding home).
You can program a PIN number for family to use all the time and keep private and at same time have a secondary number with number of uses limit; say for guests visiting.

I like being able to do yard work and not have to keep the house unlocked.

The first time you step outside and leave keys inside it will have been worth getting.

It's almost hard to review a product like this: either it works or it doesn't. It works. It is extremely easy to install (less than five minutes). It is easy to program - very clear instructions. It even comes with the battery installed! The only caution - make sure that you order the right model of remote for your model of opener!
