Convert Dumbbells into Kettlebell by SEWD – Adjustable Weights & Up to 220LB Capacity Kettlebell Handle for Weight Lifting, 90-Degree Rotating Handle, Compatible with Dumbbells (max 1.5" handle diameter, min 4.5" handle length）

I love this. I have used it on 15 lb to 50 lb dumbbells. Works great.

They were a tight fit and hard to get the dumbbells in the slot but have been broken in with time and usage. They are comfortable to hold but they can be taller than standard kettle bells. I love that I can reuse my existing dumbbells as kettle bells for my home gym. I would love it if the handle was attached to the holder. The current design means you need to hold both the handle and the dumbbell to use the tabs to contain the dumbbell. Great value for the cost because I can reuse what I have.

I almost gave up but these work perfect for my Bowflex 1090s I tried others even the ones that are identical to this one that swivel 90°, but have a locking ( twist collar = no good) you want the clamp-ons. I won't give them a five until I've had them for quite a while they're made out of plastic so that has to be taken into consideration these won't help you do everything I kettlebell will but you definitely will help your game for Farmers carries and hip thrust save me quite a bit of money on not buying a bunch of heavier kettlebells. I just ordered 2nd one. Note they make two with clamp-ons the red and the black not sure if they're exactly the same but the reds say they're only good for 110 the blacks are good for 120 not exactly sure what they mean

While not exactly like a Kettlebell, they are as close as you will get. I am using with 50lb Dumbells for Farmers Walks and zero issues. The Quality of the prodcut is very good, good grip and easy to use. Simply place the dumbell in the slot and close the two connectors. They are a little stiff but better than too lose and the dumbell comes un-done. Regarding Value I think a twin set should be $20 something just my opinion

Works well but is a hassle to put on and take off. Ok, if you just leave it on the dumbbell permanently

Really works well. We'll made.

These work great and are priced better than the Jayflex version, which I also have. The handles on this are more comfortable and not as wide. I think these are easier switch weights too and just requires 2 snaps of the levers, as opposed to twisting off the Jayflex version. I'll take these any day.

I got this so I could convert dumbbells into kettlebells, because the women's fitness studio I attend to does not have heavy kettlebells. Last night I tried using it with a 25 lb commercial dumbell (the kind every gym has: metal handle, rubber ends) and I wasn't able to lock it. Then tried with 20 lb ones and it worked, but not with the 25 lbs and heavier. If you want it to avoid purchasing kettlebells, it's fine but if you want it for heavier work, look elsewhere. If the locking was a screw-type, it would be easier. It works well with the adjustable Bowflex dumbbells I have at home but apparently the commercial dumbbells have a slight increase in the diameter of the handle that didn't allowed me to use it with. Which is a bummer because I have heavier kettlebells at home than the ones the studio has.

Works like it should. Seems robust. Opens and closes easily. Critical advantage that you can twist it 90 degrees, as some other products otherwise have the dumbbell swinging width ways through your legs.

Fait bien et solide. Mais ne fonctionne pas si vous avez des dumbbells avec bonne circonfence de poignée genre nuobells

Very sturdy. I swing 52.5 Lb weights with no problem. The ability to put the handle in both directions is the best feature of this handle. Very versatile

I like the convenience of being to able to make my own weight with my dumbells instead of buying multiple Kettlebells but it's a pain putting the handle on. It's a decent choice if you already invested in dumbells.

I've only used it once so far BUT already had an issue. I attempted a single kettle bell movement from ground, squat to press and the latches let go hurling my dumbell through the air like a devastating projectile. Thank God no one was hurt, more importantly I was not hurt....and my weight did not break. That's not what I bought it for however that is supposed to be one of its intended uses. So, next time im going to try securing it with hair elastics 🤞. I still feel like this will be a useful product for me. The handle is very comfortable for various exercises which will be very useful on the road. If you purchase it, keep in mind not to fling it over head just FYI. Enjoy, cheers!
