I returned the laptop immediately. despite the guarantee that all will work like normal with slight cosmetic wear, you will have no idea what condition your product is really in until you receive it. TouchID sensor was completely non functional. Called amazon and got a partial refund pretty easily, but then I noticed that the trackpad was mis-clicking and that it was slightly misaligned, like it had been repaired. I set up a full return the same day that my product arrived.
