Works as advertised - Lyman Universal Trimmer Power Pack Combo 7862003

Easy to setup and use. Collet chuck allows quick and accurate locking of the cartridge case. Easy to remove, measure cartridges and install again to remove additional material if necessary. Sharpening head is very sharp and sits on the end of the rotary plunger. Hand crack allows swift rotating/turning of the handle. The assembly is a little light weight and has to be held in place by one hand while cranking with the other. A little awkward but easy enough to get use to.
