Easy to install. The only problem was that the electrical wire was three feet short so I had to add some wire to tie it in to the garage door opener.
Very easy to install, works like a charm. Excellent value for the price. Flashing laser is excellent tool for car park placement and auto shut-off is a great feature. I highly recommend this device!
Easy to install. Easy to use. I like that it pulses the LED rather than being constantly on. I like that it turns off after a minute or so. You can park within inches front and back, right and left, each time.
