This is a 2017 Model (i5-3700U/HD 620) originally bought from a refurbisher on eBay UK for around £180 GBP with 256GB SSD and 16GB RAM, spent another £100 on the Upgrades (1x 1TB SATA SSD in the 2.5" Bay, 1x 512GB B + M Keyed NVME SSD in WWAN slot, 32GB (2x 16GB) RAM DDR4 SODIMMs and an Intel AX210 WiFi 6E Card, the latter three really cheaply from AliExpress, Primary Storage was from Amazon) also came with both batteries (Internal and external) which are 92% Capacity the thing looks hardly used

No issues so far, checked all the ports, like HDMI/USB/USB-C/MicroSD, trackpad works ok, keys are good best laptop keyboard I used, nipple mouse is annoying so I don't use it at all.

It's literally my first thinkpad, I've no idea about these things sorry :(

Yeah its surprisingly pretty good!!! only tested minecraft on it so far but runs really well on it (after tweaks around 100'ish FPS) I really like it, also have a Dell Latitude E7470 but didn't post cos they are virtually identical spec spec wise.
