The envelope is - admittedly - not very cheap but with high quality and processed with great attention to detail. The Asus Transformer Pad TF300T fit in exactly. At each port was (just like on the camera and the speaker) thought, everything is accessible and all openings fit precisely. Even for the audio jack has a small recess incorporated (which is also necessary because it would otherwise certainly be problems with wider plugs).
The setting up of the tablets is also easily possible in three angles, and the tablet is completely stable.
Keyword "Ultra Slim": The whole thing - ie tablet with envelope - remains actually very compact and narrow, much narrower than for example with the AmazonBasics Case for 10 "tablets, which in any case can not be used with the TF300T, because the elastic top left constantly putting pressure on the on / off switch and the volume buttons.
So thumbs up: This case is noble and just perfect for the Asus Transformer Pad TF300T suitable, therefore from me a clear recommendation!
