>>8830017I really enjoy them. The blast effects come with caps that can fit 3mm pegs or 5mm ports, be careful applying force when putting them on a robot or weapon, the plastic is hard and can crack. It's only happened with the blue but it still works, I'm more careful with them now. The LEDs in these 3p gadgets are always hella bright, have always come with batteries, and seem to be quite efficient because my oldest ones still work. I think the LED part of the engineering is trivial, it's the 3d printing and materials that have reason to improve.
