This device is great for parlor or stage settings. Not so great for close up but can be used in
close up situations with a controlled spectator environment The device is very delicate but seems
to work very well. You definitely want to be very careful as this device could burn you quite
easily.
Children should not use this without adult supervision. If you follow the instructions
carefully it works great. The tutorial is good but throughout it Shin Lim makes it clear that he
had nothing to do with the design of this device. seems like maybe he is unsure of the device itself
or the safety of it.
With some creativity, and carefulness, this could produce some really great
effects.
