If you unscrew the tailcap about 1/10 to 1/8 of a turn after it first turns off, you can have momentary light by pressing the tailcap inwards. Unscrew the tailcap counterclockwise (as if loosening it) to turn the Sonic back off. To get light, screw the tailcap in clockwise (as if tightening it) and the Sonic will come on. And you only need to do it once, so I won't bitch about it anymore. You may have to use an awl or similar instrument, or you may be able to use a fingernail if they're strong enough. I ended up having to use the awl on my swiss army knife to get the ring open far enough to get through the hole in the Sonic's tailcap. To attach the keychain attachment, thread one of the two rings on the ends of the keyring attachment through the hole in the Sonic's tailcap. To use the Sonic, you'll need to feed it first (see below) and affix the keychain attachment to the Sonic's tailcap if you wish. The next thing you'll notice is that the Sonic is around twice as bright as an original Infinity (about the same as an Infinity Ultra, or even a bit brighter), so you can use it for jobs the original Infinity just isn't quite bright enough for. The Infinity is a bit large to go on your keychain, but the Sonic isn't.

And the red one kind of looks like a dog pee-pee, but you certainly can't confuse the two when you turn the Sonic on!!! It is really small, even smaller than the Infinity light you may already have. When you first get a CMG Sonic, the first thing that you notice is the size.
