“As Is” doesn’t automatically mean you can deceive the buyer. It simply means you have disclosed the defects as you know them, and they buyer chooses to accept the condition you presented. If you fail to fully disclose, you can still be found at fault.
Selling “as is” just means that you are selling it as it is and that you aren’t offering a guarantee on the quality of the product or returns because it’s not working right. It has nothing to do with the actual product. I am selling my used iPod “as is” on eBay. There is NOTHING wrong with it, I am just selling as is because I don’t want fufill returns or be yelled at if it breaks within 5 days of getting it. See what I mean?
You also need to disclose what’s wrong with it when you sell “as is”. You will be at fault if the buyer complains. You can’t say “oh well I sold it as is so I can’t take it back” because you never disclosed the tray problem…thus you’re at fault.
