Pretty nice product. I don't have a lot of experience with "regular" kettlebells, so it is tough to do a direct comparison, but this set up works pretty well so far. It does seem to have the feel of regular kettlebells. I haven't gotten to really heavy weights, so can't comment on how bulky it may get with bigger weight loads. The construction is solid, but I would agree with a previous review that it seems a bit expensive for what I would think it would cost to make. It does look like it will last a while. Buying or finding standard weights is not a problem, they are fairly cheap and can be found at yard sales, craigslist, ect. Overall, as it has allowed me to start and progress through 2 levels of weights, and the money I have spent on the handle and weights is still less than what I would have spent on buying a starter bell and then having to trade up.
