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

Great prduct. Sturdy enough for me.

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 have the adjustable Core Fitness Dumbbells that got from 5-50 lbs, and a flat adjustable bench I use for various exercises. This seemed like a great way to be able to do some straight bar bench presses, shrugs/deadlifts/squats, etc., even tho I'm limited to light weight (100 lbs max, as the bar weighs very little) So for deadlifts, shrugs, or bicep curls/triceps extensions, this does the job pretty well. The down side to getting the bar to your chest in order to do bench press, is that with out a rack, you basically have to snatch/clean the bar as you lay back on the bench to get it on top of your chest. It can be done by resting it across your thighs as you sit, if you're going all the way flat, you pop your legs up and can rotate into position. Doing incline chest press gives you much less room to move, and this can be difficult to do w/ 100 lbs. I weigh about 160 lbs myself, so bigger people might not struggle as much. Without a squat rack to get under the bar, there's really no safe way to get this bar across your back/shoulders for squats, unless you're going w/ light weight. Point being, know the limits for what you want to do. Also the plastic collars are disappointing, as they seem cheap/flimsy compared to the construction of the bar and dumbbell holders, (holders are also plastic, but thick and sturdy). The red screw-down collars are working well so far, so maybe they'll last as long as you don't abuse them. For $130, this is a good home gym addition if you want some variety in your equipment.

I like that I now have a barbell with adjustable weights by using this. I think it's made pretty well. My only gripe is that the collars/nuts are plastic and easy to cross-thread. If you are careful they look like they could last a while, but if you're impatient and cram the nuts on, I could see them breaking and ruining the functionality of this. Also, if not obvious, the barbell is not symmetric when using (since the dumbbells are not circular). It's not a big deal, just something to get used to.

This is perfect for home use. I have dumbbells that go from 5 - 100 lbs and this holds them all. I was worried the 100 lbs would be too much. But, the unit held the 100 lbs and there were no issues on my end. These will be great for deadlifts and farmer's carry exercises in the yard. The unit itself is very solid and I don't have too much to complain about. The only "issue" is screwing the thing closed. It can be a slight pain at times. But, overall, I really like this and would recommend it to anyone.

Seems to do a pretty decent job so far but have only used it for 10s and 20's. I don't know how I feel about putting something with much more weight in there as the clamping piece is all plastic. I wish they just used metal throughout even if they charged a bit more. Just seems with plastic, that type of stuff always ends up getting brittle over time, warps and breaks. The thin little red collar part seems especially lightweight and not sure how it will hold up over time lifting and putting the bar back down. They should have at least made that piece metal. And if the red piece breaks, then what? At the mercy of the company selling you a replacement part at elevated cost + s&h - if they even do at all. When swapping between weights, it's not really a quick and easy process either. I was reallllly hoping that it would work with my set of power blocks so then I could just quickly swap weights on the power blocks instead of unscrewing the clamp everytime, but the clamp part is just too bulky and can't fit in there; I would need to dismantle the power block handle which itself would be a pita to do every time. For what it is, it seems OK but could def be improved quite a bit. Hope it doesn't give me problems which it looks like it has the possibility to down the road.

This great for home workout. Easy to assemble.

As someone who exercises and lifts on a regular basis, this product was definitely not what I was expecting and has been returned for such reasons: - Clamps for dumbell attachments are a plastic type material and will not last for regular use. (200lb max capacity for bar would be extremely sketchy in my opinion). - Foam grip on the bar right out of the package spins with 30lb dumbbells attached. Grip will not last very long at all. - Even with the filler or spacer grommet on inside of the clamps my 1.25” grip dumbbells sits there and spins not securing dumbbell when clamped down. When performing lifts the dumbbells will slide through the clamp horizontal or vertically however the lift is being performed. - Length of straight bar is way to narrow for someone who has a long wingspan of over 6’. I think there was some great intentions here with the product and versatility with using existing dumbbells. In my perspective, a lot of tweaking and redesigning would be necessary for this to be a quality product that would last.
