It's awesome. I am definitely going to get another one from them when I jump up to 40KG. Very high quality and definitely some of the best iron ones I've handled. If you contact them, they will often give you a discount code. It's only like 5%, but still something.
When I was doing comparisons, Rogue was probably my top runner-up. I took a chance with Kettlebell Kings and glad I did. It was cheaper than the Rogue and quality is at least on par. The reason why I was initially hesitant is because there was another seller that had a similar name (might have been Kettlebell King, singular) and apparently he ripped off/couldn't fulfill orders. This place is a professional place that sent my KB with secure packaging and fast shipping. Even though I'm not a crossfitter, it was recommended to me by one (apparently it's popular in that community since they offer an array of comp bells at awesome prices).
