The Lee powder scale does work and is every bit as accurate as my RCBS. My gripe about the lee powder scale is setting it, but once set, it does measure accurately. Their powder hopper on the other hand leaves some to be desired. Sure the hopper works, if you don't mind the constant inconsistant throw of powder. Granted the incinsistancies are +or- 1 grain, but that means more time using the trickler to get precise loads. The Lee hopper also does not wear-in like the RCBS or others. The Lee is made of almost all cheap plastic parts, innards as well. It will wear-out rather than wear-in to throw a better powder load.
