And you have no problems? Mine doesn't make an air tight seal no matter where it is. Annoying, it's a really good vape but I'm losing loads of juice every fill. I'll have to compare it to a genuine, might be different, though it's supposed to be a 1:1
They're alright in my experience. Light and pretty, and didn't leak on me. I thought the levers were a bit flimsy but it's not surprising given their weight. The standard pads are a bit crap – I was never convinced by them even when bed in. Otherwise average power, so probably plenty for small wheels.
As Mark says, the complete bike is a bargain and I wouldn't let these brakes put you off.
