Along with the plastic-coated weights from the same company, the dumbbells are excellent. They do not loosen at all and open and close very easily for changing weights.

Just fine: I have been using them regularly for 2 years and they work as they should. It goes without saying, of course, that by the time you add/remove the weights, the rest time between sets is over ?

I have no complaints about the collars, but if you experience them too tight, it will damage the grip because there is nothing to stop the discs from going in too deep and pressing on the grip

It did what it's supposed to. I had previous ones with worn-out tires and luckily it has its own handle. It's fine for 10-kilogram dumbbells.

It is the second pair I bought for weightlifting. Completely satisfied with the amila rubber discs!

Good non-slip grip with screw locks that close securely. It can handle a significant variation in weights, as I have used it simultaneously with weight discs of 5kg + 2.5kg + 1.25kg + 0.5kg on each side so far.
