Versatile, Comfortable, and Perfect for Home Workouts!
I’ve been using the UNNMIIY 4-in-1 Multifunctional Dumbbell Set for a weeks now, and I’m genuinely impressed. The versatility is incredible—you get dumbbells, barbells, kettlebells, and even push-up stands in one compact set. It’s perfect for switching between exercises like bench presses, squats, and curls without needing multiple pieces of equipment.The build quality feels solid. The dumbbell plates are made with a mix of cement and iron sand, and the PE coating prevents floor scratches. The grip is comfortable thanks to the deep grooves, and the non-slip dumbbell bar really helps maintain control during intense sets.One of my favorite features is the 20mm thick foam on the connecting rod—it’s soft, breathable, and fits the neck perfectly for barbell exercises. No discomfort, even during longer sessions. The upgraded locking nuts give me peace of mind; everything stays secure, and there’s no annoying wobble.Adjusting the weight is quick and easy, and the range (2 lbs to 22.5 lbs per dumbbell) is ideal for progressive training. Plus, the whole set takes up less than 2 square feet, which is a huge win for small spaces.

Very convenient adjustment dumbbells
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.

Adjustable weight
These adjustable weights have been super handy for my home workouts. Switching the weight is fast and doesn’t slow me down, and they feel solid while I’m lifting—no wobbling or weird noises. I also love that they don’t take up much space since they replace a whole set of regular dumbbells. Overall, they work great and are definitely worth the price.

Good for beginners
To start….not sure why people are complaining about not getting 90lbs. You get what you pay for. Buy the more expensive one you will get 90. Buy the cheap one you get 20 and you have options in-between. They do use the same picture for all weight options but the short description above the choices does change when choosing a differently priced option. Just pay attention and you’ll be fine.As for the system itself…it’s okay. It is a bit annoying having to unscrew everything to change them out but for me I do one set and move on to something different so its not a big deal for me.One review stated that the kettlebell was useless when not fully loaded with weight because the weights moved around. Not true if you use the fixed nut and washer, which is included. You can add as little weight you want, just use the fixed nut and washer….pretty simple.If you are a beginner and looking for something cheap to start off with then this will be okay. For the more “pro”, spend more money and get multiple sets so you dont have to unscrew everything or look elsewhere.

Good quality product, just what we needed
This has been a great product! The equipment feels very durable and stays together, we’ve had no problem using the equipment so far and it has been a very helpful addition to our weight-lifting space. The equipment is easy to use and storing the equipment is not really a problem, everything can be stacked or organized pretty easily. I would recommend this product for an exercise space.

Perfect All-in-One dumbbells for any home workouts
I’ve been using these adjustable dumbbells for a few weeks, and they’re fantastic for my home gym! I got the 45lbs set, and it’s perfect for everything from lifts to lighter cardio. Switching weights is fast—just add plates and twist the handle. The connector makes them a barbell for squats or presses, and they double as kettlebells for swings. I also use the push-up stands for extra variety. The knurled grips feel secure, even with sweaty hands, and the build is rock-solid with no wear after heavy use. This 4-in-1 set saves so much space and money compared to separate equipment. It’s a must-have for anyone wanting a versatile, high-quality workout setup. Easy 5 stars

Defective
The concept of the product is great and I was so excited to receive it but unfortunately mine came defective. The inner threading on the padded barbell extension is messed up so one side of the barbell can’t screw into it. I added a picture of the threading and how far the one side screws in vs how it should be.
