I've been using it for a few months now and haven't had any problems. While this may leave some slight buckling marks from a single gap, the buckling marks will be very minimal if you make a double gap (cut the excess part of the runner and then trim the excess part). It's thick enough to cut through thick skids, but soft enough to avoid severe burrs. I've built about 3 RG kits, 3 MG kits and even a set with these wire cutters and have had absolutely no problems. Highly recommended for beginner model builders who want a decent pair of wire cutters but don't want to spend the money on the GodHand SPN-120.
