HTZSAFEDriveway Alarm Receiver- Extra Wireless Plug-in Receiver For Solar Alarms- Up to 4 Zones and Each Zone has 35 Optional Melodies- 4 Adjustable Volume Levels

Driveway alarm works perfectly

This extra receiver works well. Pretty much programmed itself after I put it in sync mode. Didn't even have to touch the sensor which was already on and working with the first receiver.My main problem (and not a real problem, per se) is that this new receiver has all new ringtones, so I can't match the same ringtone with the original receiver. And I can't find a good ringtone yet that I like. I have a couple I tolerate, but wish it had the same ringtone as the other one.But it works, it was simple to setup, and we have an extra one, so I'm happy for that, so won't complain too much and will just get used to the new ringtones.

All four of the sensors work great. Second season and still perform well. The furthest distance is about 300 feet and goes through 3 walls to get to the receiver. Easy to program, with excellent location description choices.

Used it for driveway monitor on a farm, distance to main gate is quite a distance and units work perfectly even through trees and obstacles, no false triggers. Company even has after sales contact to see if I had problems or concerns but I had no issues and easy to use. I will be definitely doing business again!

I set this up and it worked for 3 hours then the inside receiver cratered. I was of course pretty disappointed. But frankly this is inexpensive stuff and you have to expect some problems could happen, a roll of the dice so to speak. So I contacted the customer service email on a Saturday, and actually had a response that day and a replacement was on the way immediately. Got it the following Tuesday and put it in and so far so good.In my mind, customer service is of paramount importance, and these folks are on top of that game.Update: The new receiver arrived within three days. I reprogrammed the system and it has been working like a charm since. I have noticed that one transmitter sends a few false alarms during a specific couple of hours, I'm assuming it is when the shadows shift to a certain pattern. Other than that these things work very well. I have them in pretty thick brush a substantial distance away, over flat terrain.Update: These have been working for a lot longer than I would have expected. Great product.I did have a problem though, with squirrels chewing on the plastic and exposing the internal workings to rain. I caulked the openings with silicone caulk. Still had squirrels chewing so I bought two plastic snakes, realistic looking ones, and nailed them to the trees next to the modules. No problems with squirrels since and that has been many months now.
