No sharp edges, aluminum finish (certainly susceptible to scratching, I always take it in a little bag with the work), mainly made of metal and therefore stable. Convincing mechanism that delivers what it promises.
Equally, it continues: ambidextrous handle and push button on one side of this, already, the angle of the middle plastic support any and all times to adjust observed. Great system :-) Now you can fold the rest either to the back and then forward a rubber padded "trough" for placing or - the whole thing upside down - so that SP / tablet on the wider metal surface (back of the "gutter") comes to a stop , The latter version I have with my Samsung Galaxy Note 3 take, because by the "channel" the lowest keys could not be used. Now even accurately adjust the desired angle, finished. Holds, looks good and is really convenient!
Here also the only possibility for optimization as desired to the manufacturer: but please bring a small silicone anti-Wegrutsch Strip back the channel on, between the two gray rubber-storage buffers. This prevents namely perfect slipping forward. I now have attached myself appropriate foam adhesive buffer; beautiful seeing but of course from a transparent strip. The width of the stand is made so that narrower smartphones but also tablets have good grip. So one always has a holder for your device.
Otherwise, for me there is nothing to criticize - looks totally chic, works flawlessly and is therefore finally a thoughtful, noble "Parking" for smartphones and tablets. Would I buy again :-)
