The Original - As Seen on SHARK TANK! Converts Your Dumbbells Into Kettlebells - Made in the USA - Dumbbell Grip Handle

Grips me metal weights well. Better than buying kettle bells especially if you already have the weights.

Great concept, easy to use and gets the job done. Much better option to purchasing kettlebell line... just convert what you have.

So excited this fits great for my dumbbells, I have the hex cap dumbells. I was debating on getting kettlebells to at to my home gym and stumble upon this!! Such a great find to save money! Right now highest weight I have in dumbells is 25lbs and it fits great and comfortable and feels sturdy and safe as far as the dumbells fitting securely in the clasp.

easy to use, space saver (no need to buy kettlebells if you only have dumbbells). Price needs to be lower as the cost of a kettlebell (depending on weight) is almost identical to actually buying the kettlebell.

Work very well.

Great idea for those old dumbbells sitting in the garage.

Very well worth the money. My grands constantly use them, and they fit all of my weights.

While mechanically these work by design I find them somewhat dangerous to use as the plastic handle is very smooth and your grip can easily slip regardless as to whether your wearing gloves or not. I think there should be some rubber material or something there to make them more safe to use.

I’ve been using the Kettle Gryp almost daily for months, and it’s hands-down one of the smartest, most durable fitness investments I’ve ever made. As a huge kettlebell enthusiast, I love the versatility of KB movements—but storing a full set is impractical. This ingenious gadget solves everything! Why it’s fantastic: ✅ Durable & Strong: Made of seriously tough hard plastic, it handles heavy dumbbells without flexing or wear. I’ve had zero issues despite daily use. ✅ Seamless Conversion: Slides securely onto standard dumbbells, instantly transforming them into kettlebells for swings, cleans, TGUs, and more. ✅ Lightweight & Portable: Weighs almost nothing, making it effortless to toss in my gym bag. Perfect for home workouts or on-the-go training. ✅ Clasp Confidence: I initially worried about the locking mechanism, but it’s **rock-solid**. Dumbbells stay locked in place, even during explosive movements. ✅ Space & Money Saver: No need to buy expensive kettlebells—just use your existing dumbbells! Storage is a non-issue. The design is absolutely top-notch—every detail feels intentional. Whether you’re a kettlebell devotee or just want to expand your dumbbell workouts, the Kettle Gryp delivers exceptional value. For resistance training equipment, this is a rare 10/10. I recommend it without hesitation! Final Verdict: Durable, brilliant, and utterly reliable. Five stars—worth every penny!
