I did one wheel, left it on for a few days and ended up taking them off.
At a distance they were ok. But up close my brain couldn't get past them being stickers and not on perfectly.
The radius is not quite right on the stickers IMHO and it's very hard to put them on consistently (perfectly centered between the spoke).
A co-worker had an interesting suggestion. To offer a Dark Gray (like the Tesla Midnight Silver). It would have the same effect but not be so glaring to announce itself (and associated imperfections in installation) when closer. Just an interesting thought.
I don't regret trying them.
