motion detector chime

We have tried many other door bell entry systems for our shop. All the cheaper ones only lasted a month or two. Also they only worked when the doors were physically opened. Now the new unit works as people cross into the thresh hold by movement alone so we can open the doors and still hear people walking in. It was very easy to set up and so far so good. The only very slight drawback was a limited choice of ringer sounds but the normal "ding dong" is fine. No one sneeking up on us any more!

Ordering was easy, shipping time was quick, and installation was simple. product works great and I recommend this productsfor anyone who runs small business like mine. But, I wish the transmitter was power operated instead of battery. I would go nowhereelse if I need one in the future.

Works great!

This is exactly what we needed for our therapy clinic. I purchased another brand first but it was very annoying. It had only three volumes and the low volume was way too loud. It had 52 chimes but all except for one were tunes/songs which were completely unacceptable for our situation. This unit has a volume **** which gives you complete control over the volume. It also has more sounds that are appropriate for a therapy clinic instead of tunes/songs.

Fast shipping. Worked well for the intended purpose (annunciate when customers walk up to a sales counter area when salespeople aren't present).

The sending unit I received had a defect. I contacted you by email. Almost immediately you replied that you would send me a replacement. I repaired the defect and telephoned you and said do not send me a replacement. All is working as designed and I thank you for your immediate (10 minute) responce. You stated that you will inspect all the rest of the units before shipping to other customers, unusual service, keep it up.
