Dumbbells fine, packaging not the best
So the 50 pound dumbbells I got are great (thankfully), no loose heads or issues overall. The finish isn’t the best, they have some chips and damage to the finish.I didn’t love the packaging. They were in two cardboard boxes (for each dumbbell, they were delivered separately of course), both of which were destroyed, filthy, and wet since it’s been snowing here. One box was entirely open on one side, however given the weight of these I’m not surprised and I honestly feel bad for the delivery driver who had to deliver two 50 pound boxes to my door. So, thanks to him.But either way, the packaging really wasn’t good enough for 50 pound dumbbells. They had a plastic bag wrapped around them inside as well, which seemed to be extremely old and dirty. The plastic was torn and destroyed, so I’m guessing these have been sitting around for a long time.They were dirty as well, but nothing a little alcohol can’t clean. I cleaned the floor and vacuumed after unpacking them, which took a few minutes.I held off on ordering dumbbells this heavy online, but went for it this time (I got 40s in the past which turned out great, but 50s seemed like I was pushing it for a delivery driver). It turned out fine in my case, they are not damaged in any meaningful way (again the finish isn’t perfect but I don’t care at all, they’re just dumbbells). Maybe I got lucky but I’m very happy in the end, after the slog up the stairs and the cleaning. Can’t really ask for more when buying 100 pounds of stuff online.

I like the hex shape for sturdiness/non-rolling. I use it for push-ups on occasion.
For me, 20 lbs is the perfect size for weight x reps, ideal for ALL of the routines that my wife and I do. Butterfly, squats, lunges, crunches, farmer's walk, and any back/shoulder/bicep/ab work that we are looking to do.
Never been disappointed by CAP products and accessories, and that's why this was a go-to for me. The good price is just icing on the cake.

4.0 out of 5 stars Great dumbbell, but not as good as they used to be
Reviewed in the United States on February 8, 2024
Color: Black, SingleStyle Name: 25 LBVerified Purchase
I actually bought this to replace a dumbbell I purchased from Amazon during the pandemic. The one I replaced was not made by CAP, and was pretty poor quality (chipping paint, shoddy casting and assembly, etc.). I also have an older CAP dumbbell, just like the one I'm reviewing here, and the quality is excellent. This new CAP dumbbell looked nearly perfect when I received it but, surprisingly, there were a couple of dents. It's held up well, but I am starting to see some small chips, leading me to think that CAP's quality control, post pandemic, has slipped a little bit. I still think CAP is the standard for this type of dumbbell, and I'd probably buy another one, but it's not quite as nice as the one I bought 5 or 6 years ago.

Each one may cost a month's gym membership, but I guarantee this thing is going to outlive me.

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.

Perfect! and the price was right compared to other dumbbells here with the same weight of 25lbs.

Update... I noticed they upped the prices considerably in caparison too what they were when I fist bought these dumbbells. I bought these dumbbells from 5lbs all the way to 30lbs, The 40lbs was 60 dollars and now it's at 74 dollars saying you save almost 15 dollars, what kind of bait and switch is this? I was going too buy the 35 and 40lbs but not anymore, so disappointed!
