This cover is a mirror image of the OEM cover which retails for 300. Looks great, fits like a glove and is made from the same materials as the Tesla OEM version. UPDATE + Suggestions for improvement: 1. Technically it is not waterproof as it will get wet inside but will not pollute the car. Keeps the car clean even in heavy thunderstorms.2. If it was a bit bigger at the back it would fit even tighter without the tether if you have a Performance.3 spoiler. I usually load a small load onto the trunk so the wind doesn't blow it away. However, it deserves 5 stars because it's an affordable $300 OEM cap mirror and it doesn't miss anything the OEM has to offer.
