The verdict
This kit throws in eight pieces across four resistance levels, which on paper covers beginner to advanced in a single purchase. Aggregated reviews are solidly positive on value, less so on the finish, and the bite is generic rather than ergonomic. It's a reasonable way to test which resistance suits you before committing to a nicer tool. Masseter training only — no effect on fat or bone.
