Fine bit of fun! We enjoy shooting (rubber bands) at politicians on television. So much so, I bought a pair for my two adult children. A light sanding and waxing should ensure continued smooth action. Slightly shorter rubber bands are more powerful (accurate), but are more prone to breakage. Remember that rubber bands are bad for cats.
Fun to build, fun to play with. Instructions are unclear about some things. Need to use common sense. Creative design to run the trigger and the slide.
Nice piece of woodcraft, fun to build. Spare parts are great if anything goes wrong. Spent hours building it.
