Comfortable handles and amazing quality for the price. The rubber helps a lot in preventing slipping when using it for exercises like squats or preventing it from slipping off the bar. I recommend it!

These particular discs are the most affordable in their category. So don't expect amazing quality.
The biggest negative for me is that while the picture shows a metal ring in the hole where the bar goes, in reality there is nothing there !!!

It is just rubber, which makes it quite difficult to put them on and take them off the bar, given that they are also 20 kilos and stick to it.
For 2-3 euros more, you can find similar ones with a metal ring inside!
