    • good sturdy weight

    • 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

    • It’s exactly what does what it is supposed to w
It’s the right weight. No sharp edges. You can do what you need to with it. The finishing is a little rough in some areas, but that’s only cosmetic. It’s cheap and it works.

    • Good price, low quality, packaged well
Color: Gray, Single Size: 20 lb
Cons - Quality control at Cap is definitely lacking. I bought 2 dumbbells, one came in decent condition but the other one was not as good. I had to file down sharp burrs at the welds that I could feel even through my gloves. The knurling was almost nonexistent. Both have already have chipped paint but no holes and they have a strong paint smell that I’m sure will dissipate. Pros - The dumbbells seem balanced and the heads secure. They look decent and match my existing set I bought about 15 years ago. They were packaged very well with styrofoam molds on the heads and in a sturdy box. The two boxes were then placed in a larger box. I paid a $1.00 a pound on sale, much less than the $1.50 I’ve paid at the cheapest chain sports stores. Conclusion - Per doctor’s orders, I’m lifting to keep muscle mass, not compete in power lifting or body building. They’re not Rogues, but they’re more than sufficient for my purpose. I rolled the dice and got a decent pair at a very good price so I recommend them for anyone with the same goals I have. ... show more

Great grip on the handle, if you dont like the coarse texture look for the rubber plates dumbbells, they are smoother. This thing is old school.

I got a 45 pound one and it is exactly 45 pounds which is nice because it does say 45 on it but when you try to pick it up it feels very heavy? They should consider to make their 45 pound dumbbells weigh like 25 pounds and then it will be easier to pick them up? I like the knurling on the handle it has a very nice grip and you don’t have to wear fingerless gloves like you were working out in the 1980’s or something and no one will make fun of me for it anymore ❤️ I put it with the other matching 45 pound one in my basement and it looks very nice I highly recommend that you order one of these but don’t try to pick it up too much because it is HEAVY Does the Amazon delivery driver get angry if I order heavy weights? He was very nice about it when he brought it but I feel bad I love you 😘💕 ... show more
