  • Good quality, classic dumbbell
Color: Black, Pair Size: 5 lb
The media could not be loaded. Bought this pair of 5lb dumbbells (also bought the 15lb pair). No fuss, just gains! The 5lb pair is comfortable to hold with its smooth handle. It doesn’t have the rough grip on the handle like the 15lb pair, probably because you don’t need the extra grip for lighter weights. They are good size for storing away, and are a good deal at less than $2/lb. All the weights these days have some type of prop 65 warning, which is super annoying. I figured cast iron might be less toxic than all the rubbery type weights, but I have no idea. ... show more

  • Good for the price
Color: Black, Single Size: 80 lb
I’ve bought quite a few of these (pretty much a 5-50 lbs set and a set of 80lbers so far). I will list the pros and cons : Pros: 1. Cheap. You will not find decent dumbbells for this price anywhere, besides maybe Craigslist. But then you have the pain of dealing with Craigslist and going and picking them up. Dumbbells from most other sources are 2 or even 3 times more expensive, which compounds significantly if you need a full set. Cons: 1. Chip easily. So easily that they sometimes come slightly damaged already. If you are throwing or dropping these, you’re going to destroy the coating within months. 2. Essentially no knurling. Hasn’t been a big deal for me this far 3. Not as pretty as the more expensive dumbbells Overall, it’s a decent product for what it is. For me I don’t need something pretty - picking up an ugly piece of metal has the same effect as picking up a pretty piece of metal, but for half the price. If you buy the “used” ones when they pop up, you can get them for almost $1/lb. Again, you won’t beat that anywhere right now. Every “used” one I’ve bought has come in the same shape as the “new” ones (an unused dumbbell with a chip or 2 out of the painting from manufacturing/shipping), so you’re getting the same product for slightly cheaper than they already are. ... show more

  • ONLY ONE
Color: Gray, Single Size: 10 lb
Guess I did not read close enough, I was expecting two. Have now ordered a second one. For the money they work. I am too cheap to spend more for the plastic covered ones.

  • Don't buy the heavy ones. Absolute nightmare and shipping is pathetically inadequate.
Color: Black, Single Size: 65 lb
I wish I could give 0 stars. 0 starts to cap for the quality of these dumbbells. 0 stars to amazon for the packaging. 0 stars to UPS for delivery. I bought a pair of the 65 lbs cast iron dumbbells. These were shipped and sold by Amazon. This was not even remotely worth the small savings over the rubber headed dumbbells I have bought many times through amazon. To begin, they ship these in a cardboard box and that is pretty much it. Only one dumbbell arrived on time. The box was absolutely shredded from trying to contain 65 lbs of iron. In fact, the dumbbell was falling out of the box when it arrived. The UPS man also just dumped this at the top of the driveway. This dumbbell has also defective. One of the welds was poorly done and visibly defective. I could feel the dumbbell head wobbling when pressed over head. That's scary for a 65 lbs dumbbell. The handle itself also was poorly finished. The second dumbbell arrived a week late. Its box was also destroyed and you could tell UPS had to add extra packing tape just to hold the box together. This was also dumped in the grass at the top of my driveway. It was even worse than the first dumbbell. The dumbbell head was extremely loose from the handle. I don't know if this is a defect or damaged in shipping. I guess it is probably both. I also received a replacement from Amazon for dumbbell #1. This time it didn't even arrive with a a box. There was literally just a shipping label zip tied to the dumbbell. The sad little cardboard box they ship these big dumbbells in must have been obliterated in transit. The dumbbell looks like it was dragged across concrete. Paint was chipped and peeling off. One corner looked ground down. The welds actually looked good on this one but there was too much physical damage from shipping. I am returning them all. Maybe these cast iron dumbbells would be a good option for lighter weights or if Amazon even remotely cared about packaging. I would never again consider trying to buy the heavier weights of these cast iron dumbbells. I didn't even get one functional/undamaged dumbbell from the three they sent. I recommend you the rubber coated dumbbells with the chrome handles. I have never had an issue with those. ... show more
