## What reviewers say

**REP Fitness Kettlebell** — Only one whitelisted tester — BarBend — published a hands-on review of the cast-iron REP Fitness Kettlebell (24kg/53lb model, reviewed by Jake Boly, CSCS). BarBend scored it 9.1/10, praising the durable single-cast gravity-cast iron, grippy matte-black finish that held up in swing tests, and the roughly $55 price as one of the cheapest at this weight, while flagging the thicker 39mm handle as a potential turn-off for smaller hands.
