This was available for a very affordable price. It's slim, light and appears to be relatively well made with no sharp edges and reassuringly sturdy hinges.
Used with a tablet- such as my iPad, or my smaller 8inch LG tablet, the stand works perfectly. The angle is good for placing on a deck or aeroplane tray table and watching a movie or similar. It's stable enough to not let the tablet fall over if you are touching the screen.
Unfrotunately, it doesn't work so well for phones. This is because of the width of the slots (generally thicker than a phone) and the fact that the stand is relatively long compared to a phone.
+ Good quality for the low price
+ Works well with tablets, nice and stable
- Not really suited to use with phones
