I have the 5-50lb set, and have been thoroughly satisfied with them. The entire set with the rack does take up quite a bit of space so I am considering moving to adjustable. But you can’t go wrong with this set if you’re starting out. They are solidly built (I have dropped them a few times) and have held up for 5 years now in my garage. A few have a little surface rust on the handle but that doesn’t bother me. The kneeling isn’t aggressive and feels nice in your hand.

These arent the best but they are good enough and you can find them new for less than $1lb. I have 10-45lbs and use them quite a bit. Knurl is not super grippy but the handles are functional.

These aren't the most perfect looking or highest quality dumbells. But, they get the job done. I've never had one bend or break. They've also never damaged my floor when dropped.

These are cheap white labeled dumbbells but they are just fine. I have a few sets of lighter dumbbells to pair with my Powerblocks mostly because my wife doesn't like using Powerblocks all that much. I'm not specifically recommending that you buy Cap brand as they are all basically the same. Shop around and find the best deal.

These are nice enough you want to take care of them but cheap enough you don't have to.

Not fancy or shiny, but rather valuable tools that I'm not afraid to use and abuse. I started out with a 5-30 pound set. Then over the years I bought additional dumbbells as I progressed in my training. I now have 5-50 and 65, 75, 85, 90 and 100 in my set. I use these dumbbells daily and literally beat the crap out of them. They are budget worthy and built well.

Built a set from 10-35 by 5’s. Then added a 50. Have a metal 70 just for fun’s. They work for what they are. I have some with durability issues. Otherwise, I would still be using these exclusively if I hadn’t came across powerblocks for cheap.

They’re about what you’d expect from an economy brand, nothing flashy but they get the job done. I have noticed the handle thickness isn’t always consistent even among the same weights, which is something to watch for when purchasing.

I have an rubber hex dumbbells from various vendors (Fringe, York, and Cap), and they are all virtually identical. If you want rubberized hex dumbbells, you are probably better off just going with the Cap ones, as they tend to be widely available and less expensive than the name-brand versions (significantly so, in some cases). Ultimately, they perform as expected and are probably the best value if you are looking to build a set of fixed dumbbells.

I have been piecing my dumbbells together over the years and managed to pick up these old CAP Rubber coated hex dumbbells from a friend for a great price. He got them from his uncle who had them for quite a long time, and he only had them for a few years when he realized he didn’t actually ever use them and used his adjustable dumbbells more. He kept the lighter set and sold me the 60’s and 70’s. They are great and a lot better quality than I expected. I don’t love the “palm swell” on the comfort grip, but honestly it’s not bad. I’d prefer a straight handle but it does add to the grip. The knurling feels good and allows for a good purchase in hand. The rubber is pretty well constructed and doesn’t have much wear or tear. The hex portion is a little bigger than you’d get with a cast hex dumbbell, but that’s just the nature of the beast with rubber coated dumbbells. They get the job done and I wouldn’t be opposed to buying more of the same as long as the quality hasn’t changed over the years. I will eventually try and get a pair of 80’s 90’s and 100’s but I’m not in any rush since I have loadable dumbbell handles.
