Old School
I’m glad I bought every cast iron hex dumbbell Cap made. (Except the 1 and 2 lb), in pairs from 5 to 120. After over thiry years, they are just as heavy and functional as ever. Additionally, pound for pound, they are the smallest and easiest to use for every exercise. They also take up the least amount of space to store. Seems like they’re being discontinued. Too bad. I hope they make a comeback. One of the few investments I’ve made that appreciated.

Decent dumbbells
Color: Gray, Pair
Size: 5 lb
Bought for my husband after a long hospital stay to build up his muscles again. He really likes them, quality is good. I was a bit concerned after reading some of the reviews about the handles being "rough", but he said they are fine. Easy to grip, just what he needed.

Great 25lb weight Must Have!!
Color: Black, Single
Size: 25 lb
The absolute best weight I have ever owned. This is top notch quality only the finest materials used on this. It weighs exactly 25lbs not an ounce more. This one is way better than the other one I have there is no comparison. I have gotten so many more gains with this weight. The other weights in my home gym just bow when this one is in use. I would highly recommend this weight to anyone wanting to get gains. Seriously very well balanced weight that gets the job done..!

Get in shape, or something like that
Color: Black, Pair
Size: 40 lb
I’m old. These are heavier than I remember. Time to get in shape! They are weights and they weigh 40lbs. My scale said, 40.01… I think the .01 is doing me in!

Great quality for the price
I bought both the 25 lb and 30 lb pairs and couldn’t find them cheaper on Marketplace or in local stores. The quality is exactly what I would expect from a good cast iron hex dumbbell, but at a better price. My only complaint is that I found the handles to be a little too sharp/textured for my hands. I ended up wrapping the handles with tape for a more comfortable grip. Aside from that, the quality-to-price ratio is excellent. If you’re looking for a basic set of cast iron hex dumbbells, these are a great value.

Basic no-frills dumbbell.
It’s a basic dumbbell. No cushioning no coatings to cut or fall off, it’s got a good durable no frills grey coating. It would make a good weapon if you’re carrying it while walking through a questionable area or a car tries to run over you.

More than meets my expectations.
I had purchased one of the neoprene 25 lb weights from somewhere else, but the VOC'S made me nauseous. This cast iron weight has none of those issues. Now it's a weight. If you bang it, it will get scratched. Solution: Don't bang it around. It's cast iron. The best paint won't keep it from a little rust in a damp area. I never keep my weights in a damp area. It's just common sense. It's a great dumbbell. More than meets my expectations. And the delivery was very fast!
