Once received, time it took for police to recover it: 3 days.
Final thoughts: Happy.
Full story below:
On 24 February I got robbed. They took a laptop, a LED TV and an All in One. I immediately logged into my Prey account and set my computer to "missing". As soon as I got the first report, the screenshots showed me the name of the guy who stole my belongings. I went directly to the public prosecutor's office, and the next day they recovered everything, except for the TV. On 6 March, the police finally got my things back. This app is unbelievably amazing. I totally recommend everybody to install it!
