Jayflex Hyperbell Dumbbell Converter - Convert Dumbbells to Barbell Set and Kettlebell for Home Fitness - Adjustable & Up to 200 lb Capacity Weight Barbell for Weight Lifting

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?

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.

Purchased this to be able to convert my dumbbells into kettlebells so I did not have to buy individual KBs. It’s gets the jobs done Pros: easy to use and attach to DBs. Plastic seems to be solid and can handle the weight I intend to use it for. Can orient the DB either parallel or perpendicular to the handle. Cons: the DB can rotate around in the grip but it is not noticeable when doing most movements, just makes it feel less sturdy when initially starting. Handle is noticeably wider than a traditional KB. Has a bit of a different feel than traditional KBs due to the distribution of the weight. I would definitely recommend this for anyone who already has DBs and would like KBs in similar weights but if you are wanting to focus your workouts around KB movements, I would recommend making the investment into KBs.

These are sturdy and well built. I really like the adapter that comes with it which allows me to use various types of dumbbells and the safety locking mechanism that keeps the weights locked tight. I bought a pair and really have added variety to my home workout sesssions. I recommend this product to anyone.

GREAT product. Fit any dumbbell I have. Changes out quickly. Would recommend

I was looking for a way to "create" a heavy KB in my gym or any gym I went into. This handle can swivel in positioning whether you want to have a DB inside be perpendicular or against the handle orientation. Immediately upon receiving the handle I brought it to the gym next day and attached a 100lb to it for KB swings. Though the motion does feel slightly different and a little shaky compared to a solid KB, the handle absolutely did the job I was looking for and will continue to use going forward. I would assume the thicker the DB handle the tighter the hold and the more stable it will feel in hand.

The product works fine but it’s bulky and the handle is quite huge. If you are serious about kettle bell training, buying actual kettlebells would be better. If you are just using them to do some occasional kettlebell swings and don’t want to invest in a bell just for that purpose, then this is ok.

You know when a product strikes you as well thought out and designed. This is one of those......collar and sleeve made of plastic, but if you treat it properly, you should really have no issue....unless you drop your weights, or throw them around. Very easy to fit on my rubber coated dumbells, very secure ......completes my workout needs without having to buy a whole set of kettlebells. Well done!!

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.
