The quality is fine, not outstanding. For me there was no or little neoprene stench. The narrow sides of the bag are not as well padded as front and back. Zipper cover could be more effective.
For the price (13-14 EUR) but a solid bag.
The Thinkpad X230 (12.5 "screen, 16: 9, with normal 6-cell battery). Fits in width into comfortable, stay a few centimeters at any height unsightly, but a more appropriate envelope I have not found.
