Hey everyone. I have an update for you all. After returning 2 units.
1st unit having a defect on the black paint (check under light you might have the same)
2nd unit (Buzzing noise)
I recieved my refund and put a formal complaint in with Microsoft so hopefully they can address the problem for other users.
Upon browsing for some other things, I visited at least 5 retail stores, all of different brand names to see if the display models of the SL3 did the buzzing. ALL had buzzing noise. And all were much louder then what mine was which is worrying.
I suggest if you do not feel comfortable then return it. For a product of that price you would expect if the buzzing is normal then Microsoft would alert its consumers to the fact its normal. But if they are allowing the return for a refund, you know its defective.
