This unit is a replacement for one I purchased on eBay that crapped out with great rapidity. Since it was $6.00 on eBay I wasn’t overly concerned but was annoyed. This unit is $14.19 and may also be too cheap but as of yet that remains to be seen.
I like the doorbells that have a plug in chime. That just seems so much more practical than a set of battery chimes. Sending the signal does not dramatically impact a battery but chiming does have a more significant draw, battery wise.
This is a pretty simple unit. It has 16 channels for signal transmission so if your neighbor acquires the same unit, you will be able to change channels. (A side note when one of my neighbors got the same brand garage door opener that I had, I went to my book and changed my remote back to factory default. I randomly raised and lowered his dooer for awhile until he saw me doubled over in laughter on my lawn. Lesson to be learned is always change from the factory default, whatever your product might be.)
There are only three chime tones, ding, dong and Westminster. The cheap unit had 10 or 15 but since it stopped working that really isn’t a feature to brag about.
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
