The unit programmed easy, and works fine. The clamp included snapped in half immediately when trying to install over my bars. Had to go to the hardware store and purchase a cable clamp. Worked fine. Don't see why the manufacturer couldn't have used similar materials.
We have both an automatic gate and a garage door, and it's tiresome to dismount in order to manually enter codes (or dig around in my bag for an opener button). This is exactly what I need! I got one to try and it works well, so I'm ordering more to have one on each bike!
Unfortunately, the screw that comes with the device is too short. I would recommend the other version over this, or a key chain for less fuss.
The remote works great.
