I for almost one and a half months now drive the pads daily around 15 km and they must have at this time suspend any kind of weather - snow, rain, mud - and I had at all times a good and safe feeling when braking. It squeaks nothing, it grinds nothing I can brake with a finger, and come in a very short time to stand - therefore I certify a high braking effect. When wet, you have certainly a little more pull to achieve diselbe effect on the lever, but again, that's all still in the green zone.
Wear adheres well in borders: I have not adjusted the brakes and the lever travel has become only slightly longer.
My conclusion is therefore: For the money you get rock solid quality, in my opinion, in any way bad - quite the contrary - as the Shimano. Anyway, I'll always be able to call on these brakes.
