They fit me very well, no galvanic corrosion issues as others have mentioned. I check my tire pressures at least every few months and only tighten them up. If they are over tightened you can ruin the valve stem threads and their coating and I think this is where a lot of sticking issues come into play. After years of routine car washes and the California sun, they've faded noticeably to just a faint shade of orange, which surprised me. Of course they feel much better than the cheap plastic ones!
