Review on 🔌 Efficient Cable Set with Connectors and Joiner: Saytay NEW Telephone Phone Line Tester Tool by Danielle Martinez

The name is longer than the one set. It's really just a very small, limited-capacity, single-line phone. It displays the caller's number, but only numbers, no text ID. By the way, FSK is a sound mode, it is not a pulse (rotary) phone (if there is no menu setting, all the instructions are in Chinese). The main difference from a regular phone is that it has a switch. It also shows "2009" when plugged/unplugged, but I have no idea what that means. Requires AC power to operate. When you turn on the live connection, the red indicator is lit, but instead of illuminating the display, it dims it. There are a number of seemingly identical phones out there, at slightly different prices. I paid a little more for this one. There is a trademark disclaimer. What I received was Chino-E CO19 but the seller said it was correct. There is a website but most are also in Chinese. I deducted a star for lack of helpful documentation. While it does what is advertised or shown in pictures, I'd pay a few bucks more for things like a backlit display (difficult to read in an unlit closet and using a power light for that would be trivial) and a spare cable (or just one with Plug protection - I just leave the socket when not in use to protect the lever). However, you can get this phone, a multi-channel LED tester, an inexpensive DMM, and a flashlight for less than $50.
