I did. See above: "I think there are multiple versions, depending on which attachments are included. I consider 16-22 awg a more useful range than 20-30 awg anyway."
The "blades" that cut the insulation of the wires are modular. You can buy replacements, and different sets of "blades" will cut a different set of wire gauges. Since I find 16-22 a more useful range, I wouldn't hold out for the 20-30 AWG version.
