Review on ITTECC Internal Speaker MacBook Retina by Cynthia Broederdorf

Upon further checking after spending all night and day trying to see how the speakers work, they both purr like they're getting light blown out. It's not as bad as the originals where the left one was completely broken and the right one was fine. Too many problems to bring back. I should have just bought genuine Apple hardware. TO UPDATE! I emailed the seller and said I don't want to go through the return/refund process as I would be willing to eat $20 as a loss. But I asked if it would be a problem for them to just send me another pair to see if they would work. Well they did and after I installed them they worked great! I am satisfied and will order from them again. Rumble like speakers about to explode. ********** 8/3/2018 I think I'll look around for genuine Apple parts. :(
