I am in love with this. Grip, look, well built though and built, easy installation, feel like a genuine weight lifting equipment, and value of money is excellent. Easy to adjust after each workout. Who ever designed this and made this, really put his or her brains behind this product.

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.

3.5 stars If you are wanting to start working out but not spend money this is a good starter option. It was easy to swap the weights and bars to create the weights. Barbell made for a smaller framed person. We used it until we moved to a plave with a nice gym. It was incredibly convenient.

I will add photos later. 4x 2.5 disks. 8x 5# disks This allows a number of different combinations up to a 50# barbell or 2x 25-30# dumbells. I haven't tried the kettle ball yet but I think you could get 25# (5 disks It only takes a few seconds to piece together a full barbell. Transition should be pretty smooth to go between weights or dumbbell/barbell. To be honest though, I should of bought the 70# or even the 90#. I typically can't bench more than 50#, my arms are thin. this gives me a nice range to work up to another level. or at least stay toned. This might be good for a teenager who is new to working out. The investment is nominal and if I stop using it I won't mind the cost and can donate it to charity later. If I step up to the next levels I will be able to have barbells and dumbbells' together and a fuller set and have a smoother workout. There is no reason to scoff that these are plastic. They are most likely sand or a concrete under a polymer shell. They make it easier to handle and cheaper to make but without sacrificing quality. There is no real reason to have metal or lead for weights that make them more expensive. Thermo plastic is fine. I would not slam or drop these, but you don't need to soft handle them either.
