Neat, useful little tools. Now a bit of parental paranoia.
Tempting for adventurous, little kid fingers, though. If you get them, do secure the tools and sufficiently teach (threaten) your little ones so they are aware of the risk of injury.
To children, little tools = kids toys (safe). These tools could promptly maim them.
I was gifted some similarly cool little Dremel brand mini table saws and other tools and admonished by the giver to be very cautious with them around my small children. First thing when I got the things plugged in, the curiosity of my children was demonstrated (without injury) and a good teaching/warning conversation ensued.
