Unfortunately, zero points are not awarded! Simple and brief description - a "scrap product"! Held exactly one half nail magazine, then the switch got stuck! After repair disassembly turned out that the whole structure consisted mainly of cheap, soft plastic unusable! By the weak plastic pen holder / recirculation jammed and broke the "leadership" for microswitch! The construction keeps the weight of the engine and stroke work on time and not tangled up, hence the break! Not recommended and not to be used for its intended purpose! But fit as showpiece!
