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

Grabbed this on sale via Amazon's Prime Day deal. Seemed like a better solution than buying a longer bar and using olympic weights (at least here I can use the dumbbells I already have). It's a solution and will work - but it's not a full replacement if your intention is to do full barbell workouts. I however, only plan to do limited barbell workouts with dumbbells being used primarily. As such, it is a solution that saves space, money, and suffices. Others mentioned the dumbbells slide and move within the clasps, but I do not find that to be the case. I am using amazon basics dumbbells and they are not flat (they are lifted and rounded in the middle). The jaylfex has foam inside the clips and along with the rounding it stops any movement. The problem with the solution is that the dumbbells are awkward. This means the weight is sort of dispersed incorrectly and when you pick up the bar it flops so the dumbbell is north and south (rather than how most of us hold them east and west). As I say, depending on the exercises you do, this may not prove to be an issue - but it should be noted that the bar prefers to be in a certain position. If I bought at full price I'd probably return, but at the Prime Day price I paid, I'll just keep it and use for shoulder shrugs and hip raises.

Great prduct. Sturdy enough for me.

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.

I just got mine today. The hex dumbbells that I have, they do move around just a tad due to the length of my dumbbell handle like some other reviews mention but the exercises I’m using this for, they do not move at all (RDLs, bench presses etc). I also placed an extra piece of foam in there and it eliminated the moving completely. I think ima rig up something more firm to use if I feel like it’s an issue.

So far, so good. I bought this to pair with a set of Snode AD80s for heavy dumbbell hip thrusts, squats, and lunges. It securely holds the full 160 pounds and has made all of these exercises much easier to perform. For heavy hip thrusts in particular, it’s a big improvement over my old Velcro hip-thrust belt. I added a rubber barbell pad, and the whole setup works great.

I use this everyday and it has yet to fail, the max load I've ever used is 45lb dumbells. So far so good, my workout space is limited so this hits the mark.

Love this! Has brought a whole new level to dumbbell workouts. Great quality doesn’t take up a lot of space and seems to work with a variety of dumbbells. I have both the hex dumbbells and some rubber handle and no problem switching things out.

Bought this to use with the adjustable dumbbell I bought - but the dumbbell handles are way too big. Thus had to return it. Minus stars; for lack of response by seller and also the item was advertised with free return but asking me to pay for the return label(!) Not able to reach seller; and thank you to Amazon Customer Service for stepping in and got them to send me a return label.
