Bought 2 sets of these a while back and have been able to get some really great use out of them.
After probably around 40-60 trips to the crag, these have shown little wear, with no significant wearing of the metal, although the paint on the bottom biner has rubbed off.
They're relatively light and I can clip my rope nice and quickly. The 12mm sling width is enough to keep the draws from flipping around too.
Obviously not the lightest weight draw on the market, but for the price, these are tough to beat. If you're not a gram counter, these draws are an excellent addition to your rack
