Shreq Airsoft does an unboxing video for the MAXX Hop-Up Systems and gives his first impressions if it is something that airsoft players can consider when looking for hop-up upgrades... "Hello guys, in this video I am going to unbox a Maxx Hop Up unit and give you my first impressions on the product. After I unbox it I will talk about it's features and then show a second Maxx Hop Up that has a built in tracer unit so that you can use glow in the dark BBs."
