These aren’t the newest product out there, being revealed in late December 2011 by Urban Taggers, but it looks like they’ve finally hit the states. On the Toys r Us site, the single blockade is retailing for $14.99. And the double blockade is $24.99. Seems like reasonable prices, but I think you can make cheaper ones with PVC pipe and some tarp.
Reveiws seemed to be a bit mixed, and it seems like it’s outdoor use only. So if you do plan on buying this, keep that in mind.
