could use foam insert to grip dumbbell tight works as expected.

Great product!!

Have been using DualBells for about a year or so. It's one of the tools that I use as a trainer, and it is super useful for me. Some clients only have dumbbells. A barbell has a ton of other benefits that dumbbells are missing. DualBell really came in clutch.

Genuinely smart product that has made my toolkit alot more verstile.

Great Space Saver When Paired with Adjustable Dumbbells

Works well with my NordicTrack 55 Lb. Select-A-Weight Dumbbells. With a cheap standard bar, I can add barbell excercises using my dumbbells.

Great idea to make better use of your dumbbells

What a great innovative idea to be able to use my dumbbells to add weight to my bar. Perfect fit for the dumbel and really high quality finish.

Super responsive and friendly seller.

Better than the Jayflex Hyperbell

I tried the Jayflex Hyperbell first and it didn't work well with my Ironmaster dumbbells. The Dualbell fits the Ironmaster handles better. The Dualbell attachments also replicates the effect of a rotating collar of a olympic barbell. This makes it a lot less awkward to handle than the Hyperbell.
