Adjustable Competition Kettlebell

I have had my KB since Oct. I got yellow because I just wanted something other than black in the gym. The bells arrived, and they looked great. The yellow popped, and the finish was smooth. Recently, I took them with me to an annual training event. They traveled a few hundred miles with me in the back of the truck. No issues! Unfortunately, when I returned and transferred them back into my truck, I noticed when I got home, the speaker mesh had worn off the paint just from them shifting in turns and stuff. Today, I went to change the weight for a specific new program, and when I separated the halves, paint started to chip around the seam. Truly, when the paint gets bad enough, I will refinish them because they're really awesome and a space saver. The only reason it's not a five is that the paint is coming off too easily for an item that gets banged around by design.

I like how sturdy the item is, including the tech for holding the individual weight pieces. Although it may take a few minutes over that other more easily adjustable brand (that uses plastic tabs), this feels much more solid. Hopefully the weights never crack under tension of the nut inside.

What a fantastic product and just great Customer Service. I left a phone message with Bells of Steel UK on the 30th April 2026. I got a phone-call back from a real person that day from Amanda?( I think) from Canada. She was super helpful and confirmed I could get these delivered from within the UK and, therefore not pay import taxes or bonkers delivery costs. My Adjustable KB 12-20.5kg and the add on weights upto 32kg arrived by 6th/7th May 2026!!!. I used the KB having changed the weight down to 12kg the day after arrival. Works like a dream. Assembly is easy and the KB just feels like a premium product. I’m really impressed. My home gym is now complete. Peloton Bike, Concept 2 Erg Rower, TRX and now, Adjustable KB.. job done. Thank you Bells of Steel UK.

I bought the 12-20.5kg bell and it was very solid. The adjustment system is easy to figure out (it does take time to unscrew everything, but only a minute or two depending on how much weight you are adding or taking out). I liked the 12kg-20.5kg bell so much, I bought a 12-32kg bell when it restocked. I don’t have a lot of space or a true home gym right now. I enjoyed heavy barbell lifts in the gym for years, but my life has gotten busier and home workouts are much more doable. I hope to eventually have a true home gym setup, but these kettlebells give me a lot of variety in weight without taking up too much space. I really like how they look and how they feel. They don’t feel cheap. I decided to go for the BOS vs some of the other brands because these were the only ones that came with the 0.5kg and 1kg micro plates. Will I really use them that often? Not sure yet, but I do like that you don’t have to make 5ish pound jumps each time you want to increase the weight. Only regret was not buying my bells together to get the discount for multiple items. I’m expecting these to last a lifetime!
