Just used my super tune kit for the first time doing a full tune (hot wax and edge clean-up + sharpen). The kit is great, and after watching a few videos online I got through everything with solid results.
A few minor complaints: sharpening tool only gives you 90 and 88 (0, 2) degree angles, and you can't adjust it manually. Stone that comes with the kit is a bit difficult to work with, and the wire brush is really small so not terribly useful to prep your base. So, you might need to buy some additional tools to round out this kit.
