Good ideas but the realization is not top!

Delivery time and in perfect time, so nothing to say about the delivery and the seller's service.
The problem mainly lies in what is not said in the description of the product!
Round mounting clip, plastic, that frames the brand ASUS, which allows rotation of the tablet from landscape to portrait mode, is much too fragile. After two or three manipulations, he jumps very easily, with the risk if we are not careful that the tablet is destabilized.
The grooves, sensible maintain pulpit position tablet are not deep enough and do not hold the tablet in position correctly; she slips and falls flat at the slightest touch which is particularly unpleasant and discouraging fast to use that possibility. Good ideas but implementation is not up to par. Very reserved for now, to see usage but I have serious doubts about the quality, certainly demand too much attention in handling.
