Line 6 SOS Tuner: Anyone used one?

I just saw this in Guitar Center and thought it was the coolest thing ever. How well does it work? Do you think there's any way I could attach it to my keychain? Maybe drill a hole through it or something?

If you mean Planet Waves, I have one. For the low E A and D it works OK. For the plain strings - I can't see a darn thing. Even so, at $14, this is an interesting thing to have in your gig bag.
