Adjustable Dumbbell Set (10kg-40kg) - Adjustable Weights Set for Weight Training and Strength Training-Connecting Bar, Home Gym

Surprised by the quality. Highly recommended, easy to install the discs and hooks. Some gloves came as a gift, along with a small manual with exercises to do.

It is exactly as described, very complete and can even be adapted to do abdominal exercises. There was no need to talk to the seller.

The discs are quite large in size, but of course that's due to the material they are made of, but for the price they seem fantastic to me. The short bars weigh almost 300 grams.

My overall evaluation for the 30 kg option is satisfactory. Pros: -Fast delivery in Spain Versatile -Easy to assemble -Bring some gift gloves :D (nice touch) -The main bars are metal covered with plastic. Cons: -They are not steel discs and take up more space. The bar used to assemble the roller seems metallic but is very thin and not ferrous. -The nuts are made of plastic I don't know why they put oil baths on the discs if they are plastic filled with cement; oil is normally used for steel. I recommend it as long as they are aware that the discs are plastic and filled with cement, with the quality and durability characteristics that come with that.
