The quality of these kettlebells is extremely good. I have both the cast iron and competition, both are excellent. I would say that cast iron has more of a slightly more grippy feel on the handle due to the powder coating, also the cast iron would store easier due to them all being different sizes as the weight changes. I went with 32 plus for heavy carries etc, below this I went with competition size. I would have been happy with a full set of either as the quality really is good on both
Solid build, easy to handle
Really good quality
Fab service. Great quality and decent on delivery. Had a number of issues with another company so really nice to find a company that was simple to purchase from.
Still not received. Communication is bad
Very easy transaction from start to finish, the customer service team were also very helpful and polite when required.
