I don't believe it is IWaver. Most of the writing on the box is like Japanese. I have found some boxes that are close on the web, but not just like mine. None the less... it works great. Lots of power in the gun. I am able to shoot the gun and hit the house across the street on the second floor. You can see I have been putting it to good use. I don't have my FTP program any more or I would post a picture of it. If you would still like to see it... post an email address and I will send you the pic.
Oh... a few more things... Mine requires AA batteries, not a rechargable ones like some of the ones I have seen. Also... this tank seems to be put together very well. I have a few other off brand tanks and this is just all around better...
