The three functions of this all work properly. I'm a physics teacher and I use this for demonstrations when teaching geometric optics. The laser is actually a laser and not a red LED. The UV light is actually UV and not a blue LED. The white light is... well a white light! The build quality is okay, not great, but it definitely isn't falling apart or malfunctioning either. It comes with a little removable plastic piece that makes turning on the UV/laser more difficult. I assume this is for when you carry it in your pocket.
For my purposes, none. It does the job. It would be nice to have a stronger laser, but asking for that is like asking for it to be cheaper.. There's no end to it.
The chain portion of the keychain is a little flimsy, but again, this isn't a con to me, so it's an "other thought".
This is a nice toy or something to carry around. In Canada the UV is able to illuminate markings on money, so I suppose you could use it to detect counterfeit currency...
