OLLGEN Dual Signal FSK/DTMF Phone Call Box Caller ID Display Without Call Blocker (White)-Worked by 2 AAA Battery -Not Include

DO NOT BUY THIS PART ! BOUGHT TWO FOR MY SHOP. THEY ARE JUNK, INCOMPLETE PRODUCTS. NO CONNECTIONS FOR BATTERIES. CAN"T SEND THEM BACK. AND YES I WANT IT TO BE LOUD!! DON"T DESERVE A STAR THEY DON"T WORK. BUT YOU HAVE TO GIVE A STR TO POST IT!!!

Liked it.

Miniscule instructions that are poorly translated into English. Not intuitive regarding key use and labeling. Price is the best part.

This product is missing the metal connectors inside the battery box. I am not happy.

Dont buy wont work with batteries and has no plug

The batttery was missing the metal part would not work

This didn't perform the way we hoped.

Didn’t work on multi-extension phone system
