I have adjustable dumbbells so adjustable kettlebell was a no brainer. Always been a fan of REP fitness because they make good innovative products. Buying on Amazon is about the same give or take a dollar if you buy off their website. The kettlebell works as intended and seems solid, the weights inside clunk a little, but I haven’t thrown them across the room doing kettlebell swings yet so that’s good. I don’t drop mine, but the plastic core that holds the weights is robust. You always have that lingering thought in the back of your mind if it ever gave out. Overall, I like the product and it saves space.

I own the Titan Fitness Adjustable KB but kept my eye on this, forever. I also own Powerblocks, so was reluctant to buy this but ultimately pulled the trigger. The ability to quickly switch weights truly makes a huge difference and I find myself never using my Titan, anymore, but do switch these out for the Powerblocks for heavier work. These are well-made, versatile, and a fantastic value.

Kettlebell is great! Easy to change weight. Handle has good grip and it does not take up a lot of space.

So many good things to say about this Kettlebell, but I just couldn't give it 5 stars. Let's start with all the good. Love the shape, and feel (for the most part). The shape is very much like a standard kettlebell, so all of your standard exercises feel "right". I was looking for an adjustable that gave me the same experience and this one pretty much does it. Plus, it was a brand I knew rather than a no-name. The handle feels good, the right size for one or two hands with a comfortable non slip texture. Easy to adjust weights and enough increments that it is useful for my office without taking up much space. OK, now for the reason I took away one star. I've been using this for a couple weeks now and I found that the mechanism to hold the weights in place isn't perfect. While doing swings with it I noticed that the inner weights slipped out and jammed. To fix this I had to turn the dial down to the lowest setting and knock the kettlebell on the ground to free up the inner weights. Problem solved. I also mentioned above that I like the feel, for the most part. Inner weights rattle around a bit. I guess this is to be expected, but I'd like a little tighter lock on them, if possible. Really shouldn't even mention that tbh, but I notice it. All told, this really does what I wanted it to and I'm happy.

This is an excellent purchase for a person that wants great versatility from a single kettlebell. I needed to be able to adjust the weight so I could get great workouts and adjust difficulty as needed. The quality of the material feels excellent in my hands and have been getting great workouts. The value for the money is fantastic and the performance is superb. I do a circuit with pushups, jump rope and this kettlebell all in my garage. It’s a great addition to my home workout routine.
