I purchased one of these about 8 years ago for myself and my wife.  We both loved them. So when mine went out, I decided to reorder.  The only complaint with this one, unlike it's predecessor is that it will not allow you to reset the parking distance from the wall if you need to be in close. With the prior unit, I could set it to let me come to within 6 inches of the wall.  This unit keeps going red when I get to about 1 1/2 feet.  I tried resetting it many times to no avail.  If your garage space is really tight and you need to park really close, I'd suggest looking at other products.
