Before buying the product, I was very inexperienced to working out and using these helped me start my gym routine in a comfortable way. There's lots of different weight combinations and adjustments that make it easy to get started. On top of that, all the attachments and weights are very sturdy and I had no worry that they could break even for a budget product. Overall, very satisfied with my purchase.

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 recently purchased the Adjustable Dumbbells - 10/25/35/55/70/90lbs Free Weight Set with Connector, and I couldn't be happier with my decision. This 4 in 1 Dumbbells Set has exceeded my expectations and has become an integral part of my home gym setup. As a 4 in 1 set, it can be used as barbells, kettlebells, and push-up stands, in addition to traditional dumbbells. This has saved me a significant amount of space in my home gym and has allowed me to diversify my workouts without the need for additional equipment. I've been using these dumbbells for 2 months now, and they show no signs of wear or tear. The materials used are of high quality, and the construction is solid, making them a great investment for long-term use. I highly recommend this product to anyone in need of a high-quality, space-saving, and versatile fitness solution. It has truly enhanced my workout routine, and I am confident it will do the same for you.

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.

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!

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!

They are okay if you are using them for the full bar but the problem with the advertisement is they dont depict just how long the dumbbell bar is. If you are used to do anything with them close together like overhead shoulder press they will touch. Its a bit awkward really. Overall they are decent for anyone starting out. For those who have more experience, you're better off buying dumbbells separately outside of this set.
