Anyone know much about Firesticks?

Minneapolis MN

Description

I helped out a homeless guy living in his van. I bought him gas and food and repaired his van. He gave me a Firestick. I'd never seen a Firestick before. He told me that it would give me all kinds of free viewing... etc. I never plugged it in. I'm thinking he gave it to me to be able to hack into my computer. Is this possible? Looks like it is meant to be plugged right into a TV...
