I ordered the 16gb model because of the difficulty in upgrading these units.Upon setting it up, I see this: 8gb ram in mine. I NEVER would have bought an 8gb model.The seller will not even respond. Returns are DIFFICULT for me. No car, no printer.I only asked for a partial refund to at least be able to get the parts and upgrade it myself (which realistically would be around $50-75 in parts and labor for me).Cosmetically good but also concerned it may heat up given a bent fin on the cooling.I don’t know I just wanted what I bought. :-(
