Product arrived with minor defects. One laptop had lose SSD drive which was making noises when i unpacked. I had to open up the laptop underneath to secure the lose SSD drive back in with a screw that was missing. Its working fine now. The other laptop booted up with "cooling fan" error i had to power down, waited for few minutes and power up again to boot normally. I hope this error does not pop up again. For my troubles they refunded $25 so we're good.
