Quick verdict
LiftEvidence editorial assessment
A single-piece kettlebell cast from virgin iron rather than scrap, with a void-free surface, a wide handle, a machined flat base and a matte powder coat. Owners report a durable finish without chips and a good grip texture. Some find the handle could be wider, and it costs more than other cast-iron bells.
