Love this thing!

We were having a problem with people coming down our driveway and even following the drive around the house in order to turn around off of a busy highway. I somewhat understand since this used to be a business, but is now a residential property which makes this totally unacceptable. Before, we would catch a glimpse of them as they finished the circuit in front of our house and not be able to catch them to question them as to "what did they think they were doing?". But now!, we know when anyone drives or walks up our driveway (we're about 75-100 ft off of a main road) and can see if they are headed to the house, or just using the end of the drive to turn around (which is fine by us). This little gadget is awesome! Sensitive enough it protects both ours and the neighbors driveway which adjoins ours, and we can help keep a watch out for them if they're away. (They're good friends, and they requested this). We may add more later for other locations on the property like the shed. Thank you so much for this added security!

excellent distance

Easy to put together, this wireless mail box alert system truly works from 1/2 mile away. We have a driveway that is over 2000 feet long with the mailbox at the bottom of the driveway. Additionally, the driveway is sloped away from the home, and we still get a great signal when the mailbox is opened. Good value

Love it

I have had this for a couple weeks now, and am very pleased with it. When I first put it out, I pointed it from the garage down the driveway which is about 250 feet to the street. Well, it was picking up every vehicle that went down the road, which did not make me very happy. I adjusted to switch for distance, but it made no difference. I also had 2 trucks pull into the drive and all the way up to the house, but it did not go off to warn me. Well, I decided that it was not working properly with the trucks coming head on, but catching the vehicles going along the road, so I moved the sensor to a spot in the yard, aiming toward the driveway. Now it catches vehicles coming down the driveway, and not those going down the road. I did have to switch the distance down to the lower level, as I was picking up people entering my neighbors driveway. Now it works exactly as I wanted it to, and nobody comes down my driveway without me knowing about it. I only wish the instructions mentioned something about its placement a little better, but with a little trial and error, people should be able to make it work for their needs.
