Faithful reproduction of the 11th doctor sonic screwdriver. Note that there are 4 sets of sound and light: 1 supports, 2 trustest, 3 quick trustest, 4 fast trustest. What is really taking to the doctor!
The battery change is not wealthier. But it seems tough enough.
Not very efficient, it does not allow me to hack the PC from my boss, did not unlock my lock (I thought without my key) or staining the glasses of my friends.
