So these levers I believe are made by 1 company in China (or using the same process), and sold under tons of different badges and retailers. I bought an identical set from the2wheels.com several years ago, and here's my review of them
. The quality is OK, the paint fades badly, they wear fairly bad, and they don't have great tolerances. BUT, they are dirt cheap compared to the name brand aftermarket levers, and I'd probably buy them again, though I think their prices has gone up at many retailers since I bought mine.
There may be different anodizers now, or multiple suppliers, but I'd guess my results are pretty typical of these levers no matter who you get them from.
