The airzooka works. I stood about 20 metres from a curtain in an empty theatre and you could clearly see the "hit" as the blast of air impacted with the fabric. Brilliant.
Bought as a present for Christmas everyone wanted to have a go and few could believe how effective the airzooka is.
Unfortunately, the airzooka isn't the best made product in the world and it didn't fit together very well which made the laser pointer a bit pointless as it didn't hit where you wanted it to. Also, it takes quite a lot of strength to pull the "flinger" back which translates into a little whiplash on your wrist making aiming less accurate. Finally the bang that it makes when the catapult fires is quite loud and can scare pets.
Having said all this I would still recommend the airzooka as it is fun and at this price worth every penny.
