An easy enough kit for practice or beginners. The battery box is for 3xAA so only gives a max 4.5v meaning that when you turn the potentiometer down it goes so dim it can almost disappear, using up to 6v will prevent this. The blue kit that I chose is a pleasant colour on the eye and the kit came with 3 extra LED's so some spares for the box as well. I've also uploaded a video of it in action and some pictures in it's different states. For the price it won't disappoint.
