This is true for part time or casual use but for all day work use including travel you get better build quality and far less problems with a pro grade machine. We spend the same on a macbook, thinkpad, surface or probook for our basic full time users.
While it may be a bit overkill for someone who spends their day in word, excel, chrome and zoom we save money in the long term due to reliability. There is far less downtime and IT time spent on each user over the life of the system (3-4 years). The same is true about higher quality computer accessories.
Contact the seller via ebay messages with pics and they will either send you a replacement, give a refund, or ignore you. A lot of high volume sellers don’t even bother to check and just mark everything as good used condition. If they ignore you just request a refund after a few days.
