Like I said in my review -- This product works well for my application, but the Warranty/RMA issue remains sour in my mouth.

This works as advertised, I would recommend it

I was easy to install & works great

My 1byone wireless Driveway alarm quit working while I was

This items work really well, best part was when some at the front door , it ring really loud.

So far this item is working excellent

works grate no problems

Awesome, works great, easy to install.

This simple design works great and actually caught an intruder at our under-construction home right next to our current residence.

The first set we purchased worked well for about a year, than began malfunctioning in the manner described above

Has good volume and work OK if you just want to know if someone is close to where sensor is.

, I purchased a third Driveway Alarm and all three work very well, with different ring tones.

Well, it stopped working after working perfectly, no false alarms, for one week.

Perfect for a noisy work environment.

It doesn't always work also it seams that when it's cold out it sometime quit working

Horrible, worked when I had the receiver 5 ft from the receiver, as soon as I moved it into my driveway no

Contacted by seller and they were great working with me and addressing my concerns

Seems to be working well in a commercial environment

Overall, the price point is affordable and the equipment works very well

Pros: the sensor and receiver work well from one bedroom to another; even in the dark of night with hardly any

worked for 3 hours then quite working.

This works perfect for my 1300 square foot business

This creates work and defeats the purpose of the device itself

Already have others working well and for a long time.

this sensor is really sensitive works great

stopped working almost immediately but seller had already refunded purchase for other resons

Disappointed as it does not consistently works.

The plug in unit quit working and customer service assured me they would resolve the problem, within a few days I received a replacement sensor in the mail, works great and back in business

SOB stopped working in less than a year

This works great to alert me that someone has came in.

Great it works and good price

but once you get over that, the product is well designed and works perfectly

This works really, really, really well

Easy instructions, works perfect for our application!

It has a been working well for several weeks.

EXCEPT, when I tried to reprogram the faulty transmitter, the "good" transmitter no longer works!

How can they make this product for only $10.99?It works great, & looks great

These work great and are so nice to turn two lamps on/off without having to reach for an outlet that could be behind furniture

Sensitive, works best at night, reasonably priced, weather resistant, easy mountingCons

Work's great, BUT, birds that fly into or through the censer that will make the censer trip and on windy days the branches of shrubs will set it off also, I placed the ones I have about 4 ft off the ground that work's for me, I spent a few dollars more and got the waterproof

The sensor has been in several severe storms with hail and works fine
