Quick verdict
LiftEvidence editorial assessment
A compact steel adjustable kettlebell with a matte powder coat and a push-and-twist selector, sold in 40 lb (reviewed) and heavier versions. Owners like how easily it adjusts mid-workout, the grip and the space it saves. It covers a narrower set of weights than buying individual bells, and fewer owners have reviewed it than the Bowflex.
