After unpacking this laptop, I looked and scrutinized the whole unit. I was very impressed, because this refurbished model looked brand new! No scratches, No dents, extremely clean!The setup of windows 10 Pro was a breeze, even the 10 G network over Thunderbolt was / is extremely fast. The i7 CPU, 16 Gb Ram, and Thunderbolt work together extremely well. It only took a few minutes to get "everything" set up. After imaging the drive to my NAS for safety reasons, I upgraded to Windows 11 Pro. Now I'm even more impressed! Absolutely error free upgrade to Windows 11 Pro. I'm using a Sonnettech Solo 10 G SFP+ Thunderbolt connection and it is crazy FAST. Reinstalling my software went through error free and really quick. I can definitely recommend this seller and would definitely buy from them again. I definitely feel that I purchased a very good refurbished laptop. Naturally, the 14" screen is too small for me, but the HDMI port connects to a 27" Samsung curved monitor which is perfect for me. Having a USB 3.1 hub with 3 ports helps when connection ports are limited. I did notice that 3 keys on the keyboard needed a little TLC because they wouldn't respond 100% correct, but after Q-tip cleaning they worked as designed 😉.I'm very surprised and happy with this purchase!One month update:I have put this laptop through the paces of rigorous office work and high speed network compatibility using a 10 Gb SFP+ Thunderbolt connection. This is awesome!It works flawlessly on my 10 Gb network and can do a complete laptop NVMe drive image in under 7 minutes. Even after the update to Windows  11 Pro the system is running great.If you need a reliable and fast laptop, then check out this seller, good quality and fast delivery, but hurry, they are selling out fast!
