The charge master scales seem to be hit or miss. Remember that most reloading scales resolve .1 + or -. The gempro 250 resolves .02 + or - .04. I like mine but it doesn't trickle charge well. I use a 505 to great affect.
If you do get a charge master, the straw mod and learning how to reprogram it help a ton.
