I'm here because I ve just had 3 clamp failures over one year (don't know the band but they were like 20usd each roughly, different brands bought at different times). I'm definitely buying ultralight now, hoping I can find them in Hong Kong...

How did they fail? Did the threads strip, bolt break, aluminum clamp break?I'm here because I ve just had 3 clamp failures over one year (don't know the band but they were like 20usd each roughly, different brands bought at different times).

That's a major assumption that they are all the same material after aluminium's aluminium right? Using the right alloy is important to balance between strength and corrosion resistance, the high strength alloys are generally less resistance to corrosion. Then there's the anodizing treatment, not all anodizing is created equal, the depth of the oxide coat generated varies with treatment time and that is what leads to long life. Proper hard anodizing will help resist being scratched off by the sand and other particles that get caught up on the clamps and slowly bub off the anodizing. Keeping the surface of the clamps smooth helps with easy motion of the clamps on the o-rings. Then there's the quality of the stainless steel fasteners used, which can be quite variable - I won't buy cheap chinese made stainless screws after bad experiences with them.Thanks for the replies. I can't see what would make a $30 clamp any better than a $5 clamp, they all have the same profile and made out of the same material.
