Style: A.20LB(10LB Pair)
I've been using this set for my home workouts, and it's been very convenient. It's easy to adjust the weight, feels sturdy, and doesn't take up much space. I like that it can be used for different exercises, which makes my workouts more versatile. Overall, I'm happy with the quality and value.

This product meets my needs and the quality is good. I like the PE coating of the iron. It feels smooth and comfortable. Price is very friendly which was under $100 when I got it. Grips are anti-slip which is good. Come-in package is well wrapped and stripped and the box is undamaged. The only thing I hope is if they can sell accessories separately or include more in the box. For example, it comes with 4 kettlebell handles. But only one kettlebell rod. It would be great to come in a pair. Also, I need more fix nuts. I don’t want to assemble/ disassemble every time I exercise. It’s even better if they sell rack for storage. I will definitely get one.

Style: B.30LB(15LB Pair)
Great starter set if you’re new to lifting and want something versatile for home workouts. The ability to switch between dumbbells, barbell, and kettlebell is a huge plus, and it’s been solid for the few weeks I’ve used it. That said, it’s not perfect. The kettlebell handle is thicker than standard and can feel awkward. Some exercises are a bit clunky because the weights get in the way, so you’ll find yourself adjusting your grip. The barbell is also pretty short, which makes hand placement feel cramped. For reference I am 5'3. Overall, if you’re a beginner and want convenience over perfection, this gets the job done. Just don’t expect gym-quality ergonomics.

Super bulky! Great for cheap weights but the size for each weight are considerably larger then that of gym weights so kind of get in the way with some exercises. Wouldn’t buy again or if I could go back in time, to be honest. But usable and okay to have.

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.
