I'm a very big fan and owner of some ShopLink FLASH units. Positively love them. Have used a few of the others over the years and when it came time to buy something for
our shop it was a "no-brainer". They're less expensive, super simple, and just always work.
Jerry has been fantastic to deal with, too. Even when the issue was the nut behind the keypad. ( me ) Actually, that's the only issue there has ever been. But Jerry always responded very promptly and walked me through things. Here are a few example installations. We are installing another shortly.
