キノコの妖精 5 I have two larger "Kettlebell Suns" kettlebells which are okay. However, be aware that the handles on the lighter weight kettlebells from this manufacturer aren't sized correctly. A lighter kettlebell should NOT have a smaller handle. It should just be lighter. But the handle on this kettlebell (and to a certain extent this applies to the handle on the 12kg) is too small for an adult hand. The manufacturer doesn't seem to understand that a lighter kettlebell's handle shouldn't be sized for a child.Overall quality of this brand is quite good. The handles are machined well, not covered in defects like some others, but also not slippery. I would recommend getting the competition kettlebells from this same manufacturer (quality looks good).
