Well yeah it definitely isn't rated for anything with enough power to hurt you if it happened to blow. The leads aren't very thick from what I can tell, maybe half what a normal DMM would have, so it can't have a high CAT rating. I didn't notice if it's rating was published anywhere.
I definitely wouldn't feel safe using this for anything high power, but for small hobby bench stuff it seems adequate and convenient. It looks like it can also read and generate PWM signals and some other stuff, so it can do a bit more than a regular DMM.
