With regard to the positive, so I remember three points:
- It is indeed very easy to transport (by rolling on itself and is dailleurs sold in cylindrical packaging). This is his main interest.
- Connected to a USB port, it is always well recognized, and without conflict with keyboards already installed.
- Jaime many sensations that give the keys, but.
For negative aspets:
- The soft keys can rightly upset at first (or even permanently). Unlike me, my wife found it annoying.
- It is essential to put the keyboard on a hard surface in order to use it.
- The soft plastic may seem a bit fragile.
