Adjustable Kettlebell Handle Square Exercise Fitness Kettlebell Grip Training & Weightlifting Equipment for Men Women Strength, Conditioning & Cross-Training

I have a set of 80 lb adjustable Eisenlink dumbbells and bought this matching iFast kettlebell handle attachment because it was available before the eisenlink kettlebell handle and at a lower price. Everything is compatible. The welds seem to be solid and powdercoating is evenly coated. It claims to hold up to 35.5 lb with the shorter screws. I know eisenlink now has longer screws to use with the dumbbells to hold more weight.When the screws are tight the kettlebell is solid and everything is steel so it's very durable. I've used the original hoist/ironmaster adjustable dumbbells that this design seems to imitate plus the current iron master adjustable dumbbells and kettlebell handle. These eisenlinks feel at least as solid as these adjustable dumbbells and kettlebell handles.Downsides you need to be aware of:- The powder coat doesn't have much texture so you'll need to chalk up or wrap it in hockey tape for grip.- The edges aren't rounded at all so you'll want to wear a kettlebell guard if you want to use these for anything overhead.- Loading plates isn't the easiest. Since the handle's wider than the plates I usually sit on a bench or box and put the handle between my legs so the screw faces up. Then I just loosen the screw and add/remove plates and tighten. I tried leaning it on its side but I don't know if I like that.
