Query: Looks good and works great when it works, but....

The 530ES stopped working after a few years of use. We bought a second identical unit and the opener latch stopped working after three years of use. We like the unit when it's operational, but the quality just isn't worth the price. After researching the Internet, there are comparable units by GE for less than $200, so we'll give them a try.
