Review: Beware of free warranty replacement because it's not. - Crack when installing it. They quickly sent me a replacement, however, then they charged my account for the second one without authorization or asking me to return the broken one. I thought the pictures I sent were good enough, and that's why they sent me a replacement one for free. Except it was free after all. Second one worked good without cracking.
Review: OEM QUALITY? - This part exactly matched the broken OEM part I was replacing!

Inacceptable. Je dois payer des frais pour retourner la pièce qui n'est pas du tout conforme aux spécifications. Images a l'appui. Je suis pourtant membre prime
