Query: Tyco Shell Shocker Is The Most Unique RC Toy of 2005!

As I mentioned in a previous article, the Shell Shocker is the coolest land-based RC toy I've played with since, well ever. I purchased this review unit myself, and once I got it home realized I misread the packaging - to me it seemed that you could purchase an extra battery pack if you wanted to, but it was not 100% crystal clear that I needed to buy one of these separately. Some people are going to be turned off when they realize that they need to purchase a $30 battery for a toy they already spent $60 for - trust me when I realized I had to go back to the store I was right there with ya. Once you get the battery charged and start playing though, all that frustration will disappear.
