Color: 50LB(25LB Pair)
It's all there, and it's useful, but there's 10lbs missing. I bought the "50lbs" set, and calculated them to 40lbs. Even the ad on the Amazon website shows what each plate weighs, and they all add up to 40lbs. It's either you are unaware, unable to count, or knowingly selling the product this way. Or I'm missing where the extra 10 lbs is.

We sent these back because the threading was not very strong and the weights are in KG and not LBS. Too confusing to figure out how much weight we are lifting. Check the description first before buying to make sure they are in LBS and not KGs. The title is very deceiving.

I bought this as a gift for my husband who’s a truck driver and recently got serious about building muscle — and wow, it was a total hit! He’s also diabetic, so he’s very careful about what he uses, and this set really impressed him. Everything in it feels high-quality and thoughtfully chosen. He loved how practical it is, especially since he works out right in his truck during breaks. This isn’t just a gift — it’s a sign of support, motivation, and care for his health and fitness journey. Highly recommended for anyone on the road who’s trying to stay strong and healthy!

The media could not be loaded. Missing pieces, and dumbbells don't screw in securely. Good if it's all you have but would try another brand. The connecting bar itself will collapse when weight is added so be careful of that(because the "screw in feature is only three inches" on both sides and after that it's just straight bar and your dumbbells are rolling around inside) this wouldn't be that bad if the locks were more secure but it does get dangerous when working out with it. They even suggest in their pamphlet adding more weight inbetween the bar and the connecting bar but definitely would not do that at all-- it would collapse.
