Did my install. It was painless process for me; around 10 minutes. #3 screwdriver on a 3/8 Rachet. Slow steady torque and broke all the bolts loose.
Can't comment on driving characteristics. Maybe I will update this post later if I feel anything is relevant. Only driven the car 5 minutes to the shops.
It certainly passes the thunk test. I must have done this at least twenty times per side
The window rattle is gone when as the door doesnt rebound as previously mentioned.
While driving on rougher roads there is less window rattle when you have it cracked open or partially down.
