      I stumbled upon this kettle ball since my daughter had been asking for one. The fact that you can modify the weights to suit your needs is a great feature; take it gradually as you add on more weight. I agree that it can be difficult to figure out how to use the red slider, but I can see why that locking feature is necessary to prevent the weights from accidentally dropping out. It’s convenient to have a wide range of weights in one convenient package.
