Bottom was missing screws, and rubber was coming off the metal. Was not affecting operation of the laptop. More cosmetic than anything.
Got the new bottom and screws in the mail a few days after I ordered them, removed the old bottom, and installed the new bottom within minutes. Very easy to do.
No advice, except that a lot of repairs can be done by yourself. Saves you money. IFIXIT is an excellent website. Very convenient.
