Might be to late for you but in my opinion, i think these wheels are ok, especially for the cost. I purchased some 38mm clinchers, with "special composite technology", which was slightly heavier, than standard, but a bit more rigid, as the braking surface has a full internal radial curve between the other side of the rim. As such no lining on the rims required, as there is no exposed spoke nipples. After about 1000 km of riding, the spokes seemed to get quite loose.
At this point I considered sending them back, as I had a few doubts about the lifespan/ and structural integrity.... ( and my health).
After taking them for a service to my local bike shop, with my Look 595 bike, which was slightly embarassing, as they usually service my rock solid Cosmic Carbones. GIven that i puchased them on line, am sure my local shop was a bit shitty... Value for money is great, however you need to check for wheel trueness and quality of the braking service. Because my local mechanic hadnt serviced this type of " Chinese" wheel, he was a bit worried about over tighening and pulling the wheel apart... In saying that, the wheels are very true, and spokes all seem tight.. Only issue there is a high pitched occasional " ping " simmilar to an Alloy car head cooling sound. I put some lube where the spokes rub, and it seems to have fixed the problem.... Ive ridden them down a few descents at highish speeds (60 km plus), and so far they seem quite stable. My bike shops says the sound is nothing to worry about, which gave some peace of mind.
Only issue i have now is the $49 dollar replacement ShimaNO dura-ace pads are squealing... Ive tried to adjust them, but so far, they are not as good as the Chinese ones which came with the wheels out of the box. I would consider buying another set of wheels, no problems.
