Dwinal Randall from Maine
simple circuit
all it is a light sensor that activates a timer circuit that activates a relay for a set period of time any phone that lights up will work with it including land line phones neat item to basic for my taste though

A customer from Longview, TX
Any phone with a backlight should work
Quote from the instruction manual: "This kit is activated when the backlight of a cellular phone comes on with an incoming call. The backlight needs to remain lit continuously (i.e. it shouldn't flash) while the cellular is ringing. ... To operate this kit, you need an enclosure or location that is completely sealed off to daylight."

You can see more in the instruction manual link from the link in the comment above. I didn't buy one, but I thought I'd add this info for others interested like I was.

Backlight sensor
After reading the assembly instructions from the site listed in the previous comment it appear this device senses the screen light during a phone ring to a cell phone. Not sure why it is GSM only - I would imagine that any cell phone with a light-up screen would do the trick but I have not bought or tested this product to confirm.

A customer from Hanford, WA USA
Why GSM only?
Anyone have a spec sheet on this device? What makes it GSM only? Does it require a SIM card & active line? EDITORS NOTE: This is a Velleman kit and more info may be available on their web site - http://www.vellemanusa.com/us/enu/product/view/?id=500221
