Review on 5-50 LB RitFit Neoprene Coated Kettlebell - Perfect For Full Body Workouts, Cross-Training & More! by James Jones

I personally got kettlebells with a pretty good and consistent neoprene coating. The kettlebell cast iron is decent quality although I did see a few knicks/scratches/imperfections on the metal but nothing that affects the overall usage of the kettlebell. I think the biggest drawback with these is that while they do, theoretically, protect your floor with the neoprene coating (when placed on the ground with reasonable force) the bottom of the kettlebells is uneven. Thus, if you’re trying to do something pushing up or off the kettlebells from the floor (like a KB renegade row) these are going to be uneven and you won’t be able to push off evenly (i.e. they’ll wobble). Hope this helps.
