I bought them mainly for the nut covers and I am very happy with the purchase. The lug nut caps are longer than the OEM Model 3 and the same length as the OEM Model S. I used them on my S and they fit perfectly. I tested one on 3 of my friends and they also fit great but stick out a little bit. The center caps are the same size and fit the same as the OEM ones. They are made of black plastic, while the OEM Model 3 kit is gray ("Sonic Carbon") and metallic. Overall very good value for money, I would buy again.
