I definitely like the way they look, it took me a while to get them but that's ok. Made my beautiful old Corolla amazing. However, I did crack one in the back during installation, it's a bit painful but seems safer than stock. The crack is not that noticeable.
These caps are very high quality and very high quality. Easy to install and have a good fit. Besides, they look great. I bought a cheaper set for about half the price and sent it back because I got what I paid for. spend and get money.
Out of the box they are still plastic caps but they seem to be a little better made and stronger than others I've tried. Bought for an RV, they were fairly simple and easy enough to install. I have yet to lug the camper down the street after putting them on, but they feel a little firmer and snugger than the previous set.
