The simple “Load’n Go” on this postage system means that you can eliminate forever the chore of manually sorting your mail by weight, size, or thickness. Our review found this to be one of the biggest time saving factors with this machine, and at speeds of up to 150 lpm (letters per minute), you’re going to get an awful lot done in a lot less time. Oh, did I mention that was stamped, sealed, sorted, and ready to go at 150/min?
