AC adapter

This adapter saved me from constantly having to buy 3 C cell batteries. My Dad gets a lot of visitors and the receiver is on te loudest setting with flashing strobe lights. This setting eats those batteries but the AC adapter pays for itself!

Safety for our mother with opening door alerts

Fairly easy to install. Good selection of sounds to choose from. Box with receiver did not have double sided stick tape on small piece. Only for larger sensor. Not sure why it was not packaged as additional sensor was. We will hope this works for alerting us when mom opens a door up at night. Receiver loud enough and flashing light will hopefully wake our family member who is in the home. It took one week to receive .

Great Service

I ordered a door bell and it was in my mailbox in less than a week, standard shipping. A reply to my web order was prompt and accurate. I have already ordered a second unit from this company.

Great product

I’ve been using this driveway sensor for years and it is very good and dependable.

Knowing when packages arrive.

As we age, we sometimes don’t hear people knocking when deliveries are made, partly because we don’t hear as well as we used to. Ordinary wireless doorbells were tried, but they were insufficiently loud. The 1800 bell for the hearing impaired is louder, and useful. But I think a second such bell that rings in rooms distant to its present location would be better, especially if both bells ring after any push button is activated. EGH
