Very good!!!!!!!! It perfectly grips the screws without injuring them. Compared to the more expensive Knipex gas pliers that cost twice as much, it has several differences. First of all, at the same length, that is, 250, the more expensive one has a larger opening to grip larger screws. Secondly, the more expensive one is better in handling. You can quickly tighten or loosen a screw without removing the tool from it. It can be done with the Raptor, but with a little difficulty. The biggest advantage of the Raptor is that it is more flexible in tight spaces, due to being thinner and more compact. Personally, I have been using the more expensive series of Knipex gas pliers for years and I am very satisfied, but working with the Raptor, I can objectively say that the tool is excellent and does its job perfectly.

I can't say that I'm thrilled with the new knipex 8603 series that they have released... which I didn't buy due to the cost. But I later bought it and I'm absolutely delighted, it's superior to everything else
