Hi! I recently stumbled upon a Kindle 11th Generation 32GB that someone was selling on FB Marketplace. The price is definitely way cheaper than compared to buying a Kindle off Amazon, however, what are some things I should look out before buying? The description says it has been factory reset (is this a good thing or bad thing?) and that it comes with the box/charger. And, is there a way to authenticate? :)
