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!

Exactly as described. A very easy to assemble, use and change weights as needed. Very sturdy materials and very useful for at home exercises and weightlifting on a moderate scale.

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.

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.

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

The media could not be loaded. 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.

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.

Style: 70LB(35LB Pair)
I'm writing this review to make other buyers aware that this company doesn't advertise properly. I purchased the "70lb" set and was a bit befuddled when the shipping info came thru for "67lb" total weight. I've since weighed all 16 plates (4 plates of each weight) that came with it. I'll write the described weight/ actual weights below as I'm sure the plates are the same across all buying options. 6.5lb/6.2lb 4.5lb/4.2lb 3.5lb/3lb 2.75lb/2.4lb I know these amounts aren't earth shattering, but it's slightly over 5.5 lbs lost from the set overall. And all accompanying pieces are made of plastic so they weigh next to nothing as well. I didn't expect super high quality and I'm not even upset about it. I just thought I'd share my observations for future buyers.
