The weight plates are not made of metal but of (filled) plastics. The dumbbells are a really good investment for the cheap price! The screw for fixing the weight plates on the barbell is allerdngs also made of plastic and not like the bar, made of metal. I could imagine that may be damaged by frequent changes of weights, or by over-tightening the fastener. For the pro-life use the dumbbell is not suitable. Because of the price I can here but give no star deduction! The delivery was fast and Hermes. The packing station could not be delivered because of the size. This was told by the order from the trader by email.
I would highly recommend the free weights for everyone who does not increase the weights several times a day, or reduced and is looking for dumbbells with good price / anywhere else!. These are the windows made of plastic, I see even a benefit to (should drop the barbell of a small amount onto the laminate produced may not be a faster loss as metal).
