Not so good
Color: Grey
My ashtray was broken, so I ordered this one. OK fit, but it broke in three months.

Not OEM material, doesn’t slide as easily. Feels like it will last longer.
Color: Grey, Color: Grey
Thought it was going to be the same quality as OEM, might last longer but definitely has a different texture.
Fits well.

Very happy
Color: Grey, Color: Grey
This is a 3d printed part. It fits great, looks excellent, works fantastic. I bought the grey version.
Work the part in carefully, take your time. The seller’s video in the description is very helpful! Great alternative to dropping $100 on a replacement. Excellent value, fast response and shipping..
