Easy to hook up and use. It was a little tough to get adjusted so that he alarm wouldn't go off every time the wind blew, bu works very well now.

I have three older units (15 years)and wanted to reinstall them in my new location,however, I couldn't get them to work. Ordered four more and on receipt discovered four unused dead batteries in a row had caused the problem. The 15 year old units work just fine and as you know I bought four more. The only hesitation I had is the programming logic is complex and not written well. The units are backward compatible as well.

I've got this set up in my driveway and it catches every car that enters. Seems to work great.

We both have graduate degrees- we're not dumb, but the instructions were so poorly written, we could not make the product work properly. It was only after calling the company and speaking with a person who explained how the product worked that we could get it to function as advertised. We love it- so far!

Used an older model Optex for more than 10 years. It worked well during that time but the sensor finally wore out. I purchased another brand from a different store not realizing that Optex was still around. After hours of tying to tweak the unit and get it to work properly, I gave up and returned to store where it was purchased. Then, much to my happiness, I found that Optex was still around and I purchased the 2000 model. It was easy to install and it is so nice to have a working alert system for our long driveway.

This is a great, easy to set up system. I purchased 3 receivers to use for various purposes around my home. System gives you lots of flexibility with 4 zones available with each transmitter. It is the type of home security system I had been looking for.

I wanted it to alert me in my shop behind the house but the signal wouldn't go through all the trees. I bought a TR10 repeater and put it in the house. Now the repeater retransmits the signal out to me in the shop and it works perfect.
