It looked great and worked great for the first 3 months.  Two weeks ago, right after the return policy expired I started seeing a flashing question mark inside a folder when I opened up the Macbook.  It would take several attempts to restart (boot) the device and the problem just got worse.  After erasing and reinstalling the operating system it worked good for about an hour before it shut down displaying the question mark inside a folder.  I wasn't able to reboot the device so I took it to the repair shop (the most reputable repair shop in Warsaw, Poland).The guy at the repair shop told me that 2017 Macbook pro computers are notorious for failing hard drives.  If you buy a 2017 Macbook pro just be aware of the fact that the hard drive is a ticking time bomb waiting to fail.  It will cost me about $300 to get a new hard drive installed.  If you buy this model it is safe to assume that the computer you paid $569 is eventually going to need at least another $300 in repairs after you purchase it.He told me that I was lucky.  If I had bought a later version or the Macbook with four USB ports instead of two I wouldn't have been able to easily replace the hard drive because it is soldered to the motherboard.  Oh well, anytime you buy a used Mac there are inherent risk and there is a reason why there are so many of this particular model being offered on Amazon at such a discount.
