The Kettlestack (adjustable kettlebell) used some nice hardware and didn't try to save 5 cents. As for the handle ... it's sweet and it's strong. I have dropped mine on the handle and it didn't brake. In use, I have no preference between kettlestacks and kettlebells. MF, Minneapolis,Minnesota
I have had the kettlestacks (adjustable kettlebells) for a week and they work great. I am so happy I went with your product rather than a solid kettlebell. Being able to increase the weight in increments is very important when your doing challenging ballistic exercises. More on kettlebells !!
