What's that to?

- There is no speed control, the engines have only Volldamps on or off. But the tank is much too fast. The controller responds sometimes not at all or too slow, a simple drive around the corner, making it impossible
- Image transfer the camera is so slow that you may already be in the next room and still has a still image from the vestibule. So you can go only in view mode the tank. That we had imagined differently!
- Sound transmission worked only partially. Each cup phone is as reliable.

These points seem to be a general problem, namely still had an I-Spy Tank Toys are for my other daughter under the Christmas tree. The return goes !!

I'm not one of the many comments of here writes. But before investing, I can only warn!
