This time my negative points.
- The hole to fill is very small, it fits into any hand. So it is very difficult to extract things again when they are too heavy or too large for the gripper arm, for example.
- The gripper arm is much too weak. Even small candy he can often not be effective since the gripper can not make it "pure access" in the sweets. He will always be just that.
- The range of motion of the gripper arm is very small
Conclusion: As a gag, and as a party fun maybe okay, because then you might be able to overlook the flaws.
