I received one of these cases free with my Belinea O.book3. If i had bought the case i think i would have been disappointed, in fact i don't think i would own the case did it not come free with my laptop.
The design of this case is i think was made to make it look 'trendy' but due to the way it has been designed i find it quite impractical.
The fold at the top of the case is held down by a thin strap of elasticated material, i find this really annoying as the flap then seems to bulge out at the top.
Another impracticality i found was that there is no carry strap and since it is made for 17" laptops that are quite heavy this can be quite annoying as you have to carry the case under your arm which begins to ache after a while.
The material used is quite thick for a laptop case so should protect the laptop well. Due to there being so many gaps at the opening of the case i doubt it will be very waterproof but i never risked taking it out in the rain to find out.
One thing i do really like about the design is the bright orange colour material used.
In the end i bought myself another laptop carry case with carry handle and velcro attached to the flap so to hold it down. I wouldn't recommend this case to anyone - save your money and buy a more practical case.
