Trine Wireless Doorbell Chime/Flashing Strobe

I purchased this on 5/24/16 for my mother in a retirement condo, and it stopped working on 12/14/16. I thought the battery wore out in the wireless outside push-button, so I replaced the battery, and it still doesn't work. They don't seem to sell separate replacement outside door push-buttons, so the inside unit, which still works using the test button, is useless. NOT buying another, and don't recommend this.

One of the best door bell signal devices made. It has its own strobe light and does not require a lamp. It is so simple to use - just install the doorbell that is included with it to your door frame and then plug the device in an electric outlet. When door bell is pressed, the strobe light starts flashing a bright flash. I have tried several and this is the best.

I bought two of these units to assist a hearing impaired parent. These were JUNK. Both stopped working within a few weeks with very little use. The company that sold them (Liberty) was not willing to take them back and wanted to refer me to the manufacturer. Try tracking down all of that - after they have your money!!! NOT HAPPY...

It worked almost one week. Not worth your time and money!!!!!
