Used it to find cell phone
I use it in the house mainly to locate my cell phone , which I seem to put in various places and get distracted and forget where I put it. I checked both chips and they seem to have at least the range claimed. Best way I found to attach to phone is with a little wire key fob I found in my big box store, which fits around the hinge part of my go phone. Crude, but it seems to work.C
PIECE OF GARBAGE!
CHIRP DOES NOT WORK. DO NOT WASTE YOUR MONEY.
