Jayflex Hyperbell Rotating Kettlebell Grip for Dumbbells - Adjustable Weight Dumbbell Grips for Work from Home Fitness - 100 lb Capacity Converter for Kettlebells and Home Workouts

I really like how you can tilt them 90 degrees to have the dumbbells in a parallel or perpendicular position to the handle. Makes for a lot more versatility. The handles are pretty large, which I like as it gives a lot of gripping room. I'm actually using them on MX-55 adjustable dumbbells, so now with a set of handles I have two sets of kettlebells from 10-55 lbs. For less than $80, how can you beat that? Have used only a few times, but so far impressed with the durability. The packaging was professional as well, doesn't affect the functionality but nice touch.

This is great when it works. But gets quite flimsy for weights exceeding 20kg. I’ve had this for 18 months, and the poor thing died after just doing KB swings with a 20kg weight. I can’t seem to find any information on a warranty. I think I’ll be looking for a more solid solution in future.

Looks incredibly flimsy. They say it can hold up to 100lbs each but I won't try to swing them with such weight attached to it.

This is such a great product idea for anyone who wants the versatility of different workouts without buying a bunch of separate equipment. This dumbbell converter is easy to put together and instantly turns dumbbells into a kettlebell. It feels solid during use and works exactly how a kettlebell should. Perfect for home workouts, especially if you are short on space but still want a wide range of exercises. Honestly, what more could you ask for?

The hyper Ball converter serves its purpose, but it wasn’t for me. I personally prefer the heavier feel of a kettlebell. The handle is smooth, and I think it should be somewhat textured to provide a grip.
