    Not bad. Nice adjustability, mid fit & finish

    Pros: adjustability is nice, great to have one KB to cover so many weights

    Cons: Minor concern, but the weight plate ring backs off easily and you can feel and hear the weights rattling inside. The paint chips easily and arrived peeling where it ends at the handle. My biggest issue is that the small KB’s have poor finish on the handle and it quickly wears the skin of your hands. The larger ones are better. I’ll need to buy something to buff these ridges out before I can use them for high volumes.

    Versatile unique adjustable KB

    Unique in that I don't know of any other smaller weight adjustable kettlebell quite like this. Well made, no trouble opening and swapping plates, no chips or defects. Feels good in the hands, doesn't rest on wrist bones as it has good grip clearance.

    The only negative I found is very minor: the black paint was thick and somewhat sharp on the side of the grip where the paint ends from where it was dipped, but I sanded that down and no problems.

    Solid, reliable equipment

    I've been using this M-F every week since it arrived, and have zero problems with it. It's useful for some exercises to have an adjustable bell at lower weights than the regular BoS adjustable.

    Absolutely amazing

    This is high-quality. An absolutely beautiful kettlebell. I was hesitant to get an adjustable kettlebell because I thought the plates inside would shift or shake. Nope. Or the bottom half would wobble. Nope. Once weights are secured, I can't tell it's not a regular bell. I'm very, very impressed. I will definitely be purchasing the add-on weights to extend its range next. Then I'll buy a whole second bell.

    Best adjustable kettlebell ever!

    Adjustable kettlebell redefined. The fit, finish, and tooling allow for a fully hollow cast bell feel in an adjustable. Provided you have it fastened and torqued properly, there should be no rattling or shifting here even after countless swings, snatches, long cycle, and other movements. The window is flawless. This is perhaps the best built bell in my paddock. My new favorite travel mate gym on road-trips.
