  • Very convenient adjustment dumbbells
Style: 45LB(22.5LB Pair)
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. ... show more

  • Perfect All-in-One Weight Set for Home Workouts!
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! ... show more

  • Versatile, High-Quality Dumbbell Set That’s Easy to Use and Perfect for Any Fitness Level!
Style: 45LB(22.5LB Pair)
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! ... show more

  • Satisfied
Style: 90LB(45LB Pairs)
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. ... show more

  • Stay in shape
Style: 20LB(10LB Pair)
In all honesty I can't personally rate the product itself. However, I purchased it for my stepdaughter that recently had a child and wanted to of course get her "pre baby" body back, she was excited when they arrived (a day earlier than scheduled which was good). She had no idea, she mentioned wanting to get back into shape, so I ordered them 10 mins later. I will say this though, I do like the versatility of the set, and if you're just looking to maintain your physique and not concerned about getting ripped then it looks like a nice little set to have, I'm actually considering purchasing one for myself. So 5* for stepdaughter happiness and versatility at an amazing price! ... show more

  • Home gym must have!
Style: 20LB(10LB Pair)
I am happy with a set of adjustable dumbbells, and they have truly revolutionized my home workouts. These dumbbells are incredibly versatile, allowing me to quickly switch between different weights with a simple adjustment. This feature is perfect for circuit training, as I can easily transition from heavy lifts to lighter exercises without wasting time. After had the baby, l don’t have time to work out at my gym anymore. So l decided to build my own gym at the garage. This is the first thing l got for my home gym. 💪 Overall, The build quality is impressive; the dumbbells feel sturdy and well-balanced, giving me confidence during my lifts. The grip is comfortable and secure, which is crucial for maintaining proper form and preventing injuries. I am a former rehab RN, and l always put safety first. The compact design saves a ton of space compared to having multiple sets of fixed-weight dumbbells cluttering my workout area.What I love most about these adjustable dumbbells is their adaptability to various exercises. Whether I'm doing bicep curls, shoulder presses, or lunges, these dumbbells can handle it all. They have become an essential part of my fitness routine, helping me to progressively increase my strength. It functions well like those l used at gym. The price is reasonable! I will buy it again! ... show more

  • Not Quite What I Thought I Was Getting
Style: 45LB(22.5LB Pair)
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.
