Really handy keyring!

I've used one of these as a keyring for about 5 years now and find it really useful. It glows well and the keyring is very secure.

The units are rather large. this technology is OK but it is a shame it needs a powerful light source to make it work for any length of time and it gradually depletes as time elapses.It is a shame that the group does not offer a Tritium based option too. Whilst more expensive, it is both more compact and emits a constant light - it doesn't need to be charged with sunlight or a torch.However, these are spottable from afar when freshly charged so it possibly boils down to range. I also us Night Vision which stands out in pitch darkness.
