these things sure is getting nicer and nicer, but 40 bucks seems a lot for such a device. Also the fact, that they put a new version of these sub-tanks out each second week.. In Denmark UD tanks is the hottest shit right now, everyone buys them. I think it's the same case in many other countries. Which should also make it possible for UD, to offer the products way cheaper than they do now, without losing money.

Make it about $20, or at least no more than $20, for a UD tank, and you will se how people start spending even more money on UD products. The only difference will be that now everyone can have a chance to own a nice tank.
