Inspired by Bagnaj97's mini-review, I've decided to contribute as well
Integral Performance 120GB SSD (for £24.99 from MyMemory on 8th of May, 2018). Delivered in a jiffy bag, as a 'gift' from Switzerland. Surprisingly cheap so I wasn't expecting a earth-shattering performance. 7mm thick with a stick-on bracket, if required. 111.79GB after formatting. Fair warning, the driver performs suspiciously well.
Same as Bagnaj97, I've used AS SSD and CrystalDisk. I've compared the performance to my system SSD Crucial MX100 SSD.

EDIT: Google can do me a favour. Can't believe it is this hard to link pictures ...
