This folding stand is a useful addition to my 10-inch Thinkpad Tablet, I can thus optimally positioned in portrait or landscape mode. Due to the dead weight of the tablets the stand is quite safe. For the journey to the stand can be easily folded. The weight is low. As it is with the durability of plastic construction is, however, still have to prove.
For 7-inch tablet, the stator is not optimal. The A1 my wife is in portrait mode no proper maintenance, since the lower struts are too far apart.
