Style: 20LB(10LB Pair)
I’ve been using this adjustable dumbbell set for a few weeks now and I’m genuinely impressed! The versatility is a game-changer — you can easily switch between dumbbells, kettlebells, a barbell, and even a push-up stand. It’s like having a full gym in one compact setup. The upgraded nut design keeps the weights secure and doesn’t loosen up mid-workout like cheaper sets I’ve used in the past. The build quality is solid and feels durable, even when loaded to the higher weights. I went with the 45lb option, which gives me more than enough range to grow with. Whether you're just starting or more advanced, this set is perfect. It’s also easy to store, which is ideal if you don’t have a ton of space. Highly recommend this for anyone serious about home fitness — great value, functionality, and quality!

I am very impressed with this adjustable dumbbell set. It is a solution that has four parts. It replaces many big pieces of gym equipment. This makes it perfect for a small gym in my home. I can switch between dumbbells, a barbell, kettlebells, and a stand for push-ups. This is convenient for me. It gives me all I need for a workout for my whole body. The system for connecting is secure. It is easy to use for anyone. Changing how I set it up take only a few seconds. The weights are strong. They are comfortable to hold. They feel very stable when I do exercises. I love that I can make resistance bigger little by little. I do curls, presses for my chest, squats, swings with kettlebells, and push-ups. Each piece feels solid and well-made. This set makes my workouts at home more effective. It makes them more fun too. It saves a lot of space if I compare it to normal free weights. For the price and different uses, it is one of the best money I spent on fitness.

I bought the UNNMIIY 4-in-1 Multifunctional Dumbbell Set as a Christmas gift for my 18-year-old son, and he absolutely loves it! This set is incredibly versatile, allowing him to switch between dumbbells, barbells, kettlebells, and even push-up stands. He’s been able to do a variety of exercises, from bench presses to squats, all with just this one set. After watching the instructional video provided on Amazon, setting it up and using it was a breeze. The video was clear and made it super easy to get started, even for someone who’s new to fitness equipment. The quality of the materials is excellent. The weights are made with a durable mix of cement and iron sand encased in high-quality PE, which means no scratches on the floors. The thick, foam-padded connecting rod is a game-changer—it’s comfortable on the neck, non-slip, and sweat-absorbing, making workouts much more enjoyable. The upgraded locking nuts give me peace of mind knowing the weights are secure during use. The adjustable design and wide range of weights (2lbs-22.5lbs per dumbbell) mean it can grow with him as his fitness level improves. Plus, it’s compact and doesn’t take up much space—perfect for our home gym. Overall, this dumbbell set is a fantastic buy for anyone looking for versatility, quality, and ease of use. Highly recommend!

It's been a few months since my purchase and I'd say I'm satisfied with the product for what it is. It's useable for a variety of exercises and the set doesn't take up much space. For my purposes the last few months, it's be sufficient. Things to consider (for reference, I'm 6ft 5in so some downsides for me may not be a problem for others): -Only 4 weights can be added to each side of the bar which limits the amount you can stack. -Definitely good enough certain exercises but don't expect to be training major lifts to the extreme like you would in a conventional gym. In my case, the bar is too short but there are ways to get around it. -Weight adjustment can take some time. In terms of durability it's been fine but I don't recommend putting any major tugging forces on the assembled bar like you would with a conventional barbell. None of the points above have been a deal-breaker for me since I expected most of them when purchasing this product. Overall, I'd say this product is useful for beginners or if you'd just like a cheap way to perform a variety of weighed exercises at home.

Great set for home or office work out. Large amount of combinations and weights can be done for a perfect and complete exercise. Really recommend.

This adjustable dumbbell and kettlebell set works great. The weight plates are easy to switch, and there’s no plastic smell at all, which I really appreciate. The screws turn super smoothly, making it very easy to assemble, and the grip feels great in the hand. I set up an 11 lb dumbbell and a 13 lb kettlebell, and after a week of glute and leg workouts, I can already feel the difference—very solid and effective. The only thing to note is that the kettlebell is a bit bulky, which might be less ideal for smaller users. It would be helpful if the listing mentioned this. Otherwise, the quality and value are excellent.

Ended up coming in a day early everything was packaged up nice (was a little worried cus the box was a little mangled but obv a box with 70 sum pounds isnt going to hold shape 100%) everything like its made of good quality not some flimsy brittle plastic, havent weighed the actual weights themselves but dont think ill have a problem with them all in all i think itll be a great addition to the workout routine

From the photo, I thought that from the different components you would be able to make two kettle weights but you can make only one so if you are looking for the ability to work both arms out you need to purchase two of these kits but you will have a ton of other parts leftover.
