US Automatic Gate Openers 020320 Editorial Review
The USAutomatic 020320 Sentry 300 Commercial Grade Automatic Gate Opener is a durable and reliable option for swing gates, with the option to purchase a slide opener. The unit does not automatically reverse if it hits an obstacle but does stop, and the force can be adjusted. The unit has held up well in electrical storms, and customers have reported using a hard-wired button opener and magnetic sensor to operate the gate. Some customers have had difficulty programming modern cars to open the gate, but overall, customers have mostly been satisfied with the product for over two years of use.
