Firefly trigalight
Fast shipping, plus seller sent little bag of sweets with order. I bought 2 beta lights / firefly trigalight one for me and one my girlfriend. I will wear on a neck chain. Seems bright enough in the dark. I will test later with Geiger counter to see if any mild radiation.

Great little glow keyring
Much better quality than the Nite glowing keyring I had that snapped. For those that don't know these do not glow all that bright, so are not an alternative to a torch but glow bring enough to make them easily visible in a dark space. Nice and compact, glows as well as needed and not a bad price.

Useless expensive rubbish
Useless don't know if I got a broken one but not even remotely glowing I have perfect vision if I put it at one end of room to the other can't see it glowing in dark at all. Nothing like the other reviews pictures! I'd be disappointed if I got out of a kinder egg for 50p

Handy key finder
I have a few older Tritium vials on keys and needed a new one. This is brighter than those, but potentially younger (depending on how long the supplier had it). As such I cannot fairly compare them, but I'm happy with this one.

Excellent but expensive
It could be cheaper though, like £5 cheaper. I bought it because needing it in a hurry. But has thousands of uses. Handy, eg. for locating the bathroom light cord. Handy for tents.

Novelty, not very common, but not very bright neither
Pro’s:- build quality is fantastic- have seen worse keychains for more money- not common- cool stuff- for the purpose of a keyfinder it does work!Con’s:- pretty pricy- not as bright as the pictures suggest (tbf it is not even close to “bright”) more like a “mild glow” more than bright.- no manufacturing date mentioned anywhere so in the end who knows maybe the one i got is allready 9 years old (therefore is already lost almost half of it’s brightness)I can only recommend this to people who really want to have a “tritium key chain” i would not use it as an “emergency light” cause it is not even remotely bright enough. It can do as a keyfinder in very dark rooms!
