Some transmitters didn't work.

First off, this took weeks to get here. I didn't realize it was shipping from China or I would have paid a few bucks extra and gotten one that was Prime. I don't hold that against the seller it's just that I didn't realize that when I bought it. The actual product is kind of crap. I tested the first 3 keychains, #1 worked just fine and is on my car keys. #2 didn't work at all, and #3 works some of the time (I have it velcro'd to my Fire remote). I thought at first maybe the receiver just doesn't work through walls (even though the transmitter was about 10 feet away)- but the keychain transmitter was able to ping in the exact same location so it's just a faulty transmitter. It does ping sometimes - but every time it has been after I'd already found the dang thing and brought it close to the transmitter to test that it was working at all. Defeats the point! I'm really disappointed in this product and based on 2 out of 6 (again, I didn't test the other 3 so it might be a higher %) not functioning as they should I'd say give this particular product a pass. One of the tested transmitters DID work and works well, so it's not a 1 star - maybe I just got an old/bad set.
