Worth the price!
Love the weights. It has a rubber that makes it easy for grip and adjustment. It’s super easy to assemble. Great for at home workout.

Solid and space-saving
These adjustable dumbbells are exactly what I needed after downsizing my workout space. The different weight options are easy to switch between, and the connector bar is a nice bonus for doing barbell-style lifts. Everything feels sturdy and well made. Definitely a great buy if you’re looking to get a full workout at home without cluttering the room with tons of equipment.

Durable and comfortable
Generally good purchase with variety of uses. Weights are easy to switch out. Grip is comfortable. Twist locks hold well, but it’s best to check them before you reuse them. Occasionally rolling them will make the twist locks come loose. Easy to assemble. Effective dor working out and easy to use.

4.5 rounded up
Edited: Contacted Feierdun CS about a second kettle ball pin, and received outstanding service.Rating revised: Solid five stars.Original review:I am delighted with this set.Yes, the plastic does feel a bit cheap, and I’d be concerned about the nuts not holding up, but I have standard issue dumbbell poles, squat bar, nuts, and clamps, and these weights fit perfect on the regular metal bar and dumbbell bars that I have.For what this is, it’s an amazing value — truly. But I’m not worried about the plastic bars and nuts holding up, so understand that.I needed more weights, and the versatility and quality of these plastic covered plates is awesome — I do love the plastic coated weights more than the old school no coating metal plates. I had a huge set at one time, had to downsize to the 2.5 + 5 pound plates when I moved.I’ve been putting together a new home gym, and when these came as a lightening deal, I caved to the marketing — but it really was a good deal, and I can now use my choice of bars, and have plenty of weights to work with.The only thing that would make this better would be if the chest press/kettle ball came with a second pin so that we could make two kettle balls, not just one.Many kettle ball routines use a kettle ball in each hand, and I don’t think you can buy the little stem separately.That would be awesome — perhaps the seller will allow a separate purchase.Anyway, this set is a great addition to my evolving home gym.I’d probably be less excited if I didn’t have my own standard gym bar and dumbbell sets, but that’s okay.I think this would be an excellent set for anyone just getting started.

I wouldn’t recommend
Don’t buy, it took a long time to get to me and on top of that it’s ok quality, but the weights come in weird weights, like 4.5,3.5,2.5. The 4.5 is the heaviest one I got. They are easy to assemble, and u can work out with them but will I buy or recommend, NO.
Karrie Harris –
Perfect beginner set
The product’s design prioritizes ease of use and robust construction.

Great for newbies and multi-part training
Can be assembled to freely adjust the weight, and can be spliced lever is really so practical, compared to my previous purchase convenient and practical. Ideal for those who want to train multiple muscles. The sponge design on the surface feels great.

I recently purchased an amazing set of dumbbells and kettlebells with a connector from Amazon, and I must say, it’s a game-changer for my fitness routine. The versatility of this set is unmatched, allowing me to switch between dumbbells and a kettlebell with ease, thanks to the innovative connector.The weights arrived in pristine condition, boasting a sleek design and a clean finish that speaks volumes about their quality. Setting them up was a breeze; the easy-to-install feature made it possible to start my workout within minutes of unboxing.What I love most about this set is the comfortable grip and the sturdy construction—it feels like they’re built to last a lifetime. Whether I’m doing curls, squats, or kettlebell swings, these weights provide a stable and balanced experience, enhancing my workout efficiency.The durability and aesthetic appeal make this free weight set a fantastic addition to my home gym. It’s not just a purchase; it’s an investment in my health and fitness journey. I highly recommend this set to anyone looking to elevate their workout with high-quality, adaptable free weights.⭐️⭐️⭐️⭐️⭐️

AHMED Abdulla –
The workmanship is poor and the dumbell bar is very long and it is difficult to do exercises with it and the weights are in pounds and not kilograms so I do not need themالصناعة رديئة وعصا الدانبل طويله جدا ومن الصعب اجراء التمارين من خلالها والاوزان بالباوند وليس بالكيلوجرام وقد تم اعادتها لامزون

I really like this Dumbbell set. It has nice feel to the texture.And although plastic, (or perhaps vinyl), they don’t feel cheap.The set looks good, too. I like the Orange and Black look, compared to the other Red and Black sets available.I also really like that you can spin the orange locking nuts on by giving them a good hard spin – and they’ll keep going – sometimes all the way on, (depending on how hard you initially spin them), without having to constantly keep turning and cracking them all the way on. (Same with removing them.)The orange locking nuts have 2 opposing ‘extended nubs’ on them, to aid in cranking them down tight.There is a foam-padded area on the center bar that would touch or rest on the back of your neck, when using the bar fully extended with both arms.The two shorter individual threaded bars turn in quite far – all the way into the center bar for added stability.There are also 2 Kettle Ball Handles, and a dedicated Kettle Ball End Piece, which helps me keep a controlled grip on them, when slowly and carefully using the weights to dip behind my back and shoulders, (among other alternate exercises).The spacious openings of the Kettle Ball Handles are plenty wide enough, as well, (if two hands are required or preferred), allowing for different positions to hold, grasp, and maneuver them.For a really good product, it’s very well priced, compared to the other options available.I’m happy with the set![One Word of Caution: I would caution against dropping them, though, as they are most likely filled with sand, (or something similar), and could therefore crack and split open, if dropped from high enough up.There is a bit of a slippery feel to them to be aware of.]Each Dumbbell arrived individually protected in its own soft sleeve.
