I have the neoprene sleeve already for over 3 months in use and it is really worth gold. The material on the outside feels great and the inside is like velvet. I have made the experience that after a 30 minute bike ride to work, the tablet display is free from grease and fingerprints, which I attribute to the inside lining. I use the sleeve for my "Archos 101 G9 Turbo 250GB" and can really recommend it. 5 * from me and unconditional recommendation.
ps Whether it actually is waterproof I did not try, I will not. But when I look at the processing then to me Trust me it really the Sleeve. Has been dropped my tablet in the shell already and landed on a corner. Cover and tablet have the fall from table height survived without damage.
