Suggest looking at the chamberlain device that performs a similar function, and gets good reviews.

I also decided not to contact Amazon because I wouldn't want to give a negative review without sharing this you first.

I was surprised, given all the great reviews, but it did not work for me.

I was absolutely thrilled to receive this product for a honest review

I needed something and after reviewing different options this looked like a good option

I love this handy portable door chime which I was given free of charge to review

I got this product with very deep discount for exchange my honest review, the product delivery on time, the menu was very easy to install, I tried it on our I frontdoor, but not sure did I set it up wrong or what gap ended, it seemed not working good then what I expected.

I was given this item in exchange for my honest and unbiased review.

The company's customer service has contacted me twice to give me advise how to set these up to make them work and asked me to improve my review

I selected this one because of the good reviews it got

I hate leaving bad reviews but this product sucked honestly.

They are cheap plastic, and now that I share my experiences in the reviews, I see that the good reviews are from newbies to use, and anyone using them for any length of time remarks that they simply stop working

This item was provided by the manufacturer for testing and an impartial review.)

I was asked to use it fully and to write an honest, unbiased review

I read many others reviews as well

I was offered a discount in exchange of my honest review.

Disclosure: I was supplied a sample for test and evaluation purposes in return for an honest and fair review

Junk product (and yes, I give good reviews, too).

The seller sends requests for positive reviews.

This review is unbiased and my own.

Doesn't seem to drain batteries quickly (I *really* appreciate not having to deal with changing batteries frequently...)
