You have to be about 2 feet away from the garage in order for this to work. I read the reviews and all they mentioned was a "delay". There might be a slight delay with this remote, but that is not a problem. I can handle a milli second delay. What I can't handle is if there is another car parked in the driveway and I have to park behind that car, this button won't open the garage. You have to be so close to the door, it is ridiculous. If any one would have mentioned this in the reviews, I would not have purchased this. Terrible device. I ordered two, but will be returning them both for the larger remote...hopefully it will have a longer range.
