I use the HEDs as my every day road wheels and so far they have been great. They're much lighter than stock, the bearings are smooth, and the wide rims combined with 28mm tires is very comfortable and sure-footed.
With such wide rims and big tires HED recommends a much lower pressure than you might be used to -- I use 70 PSI (I weigh 145 lbs) which is on the high side and I might go lower (see HED video on recommended pressure). I have hundreds rather than thousands of miles on them so I can't talk about durability yet, but these wheels have a good reputation for quality.
There is one drawback preventing me from giving the wheelset five stars -- it was extremely difficult to get the tires onto the rims. You have to use HED's thin rim tape (included) and follow HED's instructions (watch their video) but even then it was very hard to get the tire stretched over the rim. You might want to consider a tire mounting tool such as the Kool-Stop tire mounting jack (I bought one for next time). I've read that tires stretch with use so I hope it's easier to get on and off, if and when I have a flat on the road. To be fair, I had another set of wheels with Velocity A23 rims (also a wide rimmed-design) and it was even harder to get the tires onto those wheels. So it may be just the way it is with modern tubeless-compatible wide/high-volume rims.
All in all, I'm very happy with the upgrade and while wheels this good are expensive, you could spend a lot more and you probably wouldn't get as much value for the money.
