I got a pair for my buddy and I. I've got nothing bad to say about them. The battery life on monitor is outstanding.
VHF+
Everything VHF and up!
FM, SSB, WSJT-X, SOTA, microwaves, there is a lot the bands 50MHz and up have to offer.
Pardon my ignorance, but what is it?
A handheld radio transceiver. Think walkie-talkie but much more capable.
And one that requires a license to use. A lot of people buy them and just use them without a license, but if you get caught, it can be a pretty decent sized fine.
Ignorant question...
What country are you referring to?
Who and how is that enforced?
I am licensed to use this equipment in the United States, but nearly all countries have some sort of requirements for licensing the use of radio spectrum.

As for enforcement, it depends on what you are doing with it. If you just buy one and start using it, it is possible that you can (accidentally or intentionally) interfere with other people's radio communication. This might mean you cause problems with someone's WiFi, or it might mean you interrupt air traffic communication or police radios.
If you use it a lot, and interfere with important traffic, then someone can use radio receiving equipment to triangulate your position (it's not super easy, but it's not too difficult to do with the right equipment)
Some radio operators do this for sport, but the FCC can and will track down major offenders.

Depending on how poorly you operate illegal radios, you can go to jail.
