I've been using my (Kettlestack adjustable kettlebells) handles about 2 months, and I couldn't be happier with them. Your product: is rock solid, easy to use, ingenious and cost effective...I had planned to buy a solid "KB" next paycheck, but I want another "KS" first. More on kettlebells !!
hi, Thanks for the kettlestack (adjustable kettlebell) handle,great product,nice to be able to use different weights,highly recommend to anyone. JD, England
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 !!
Just received my pair of kettlestack. My first thought was: "they are so light they can not handle the plates!". I was proved wrong after my first kettlebell session with them. Solid as rock. Thanks so much for the attention and for this great product. Just made my day.
