The new Nano V2 is here after a long wait and overall this is a good product. You get 40 pieces in this set including 1 nano V2, 2 platform arenas now in orange and the walls and doors slide out so multiple ones can be joined together. The helix 180 tube is also here and it flips the bug around 180 degrees as it travels through it. They really climb well and two can pass each other in the same tube going in opposite directions at the same time with no problem however two *CAN'T* pass each other in the helix tube. They simply get stuck and no knocking encouragement frees them so you have to take that part of the model apart to free them. This will become a problem if you have several running about and you may choose not to use the helix tube. Sadly there is another problem as well. The nano V2 robots simply are not as efficient and flipping themselves over like the original ones were. Even taking them out of the maze and placing them on the floor, on there back with no obstructions they can take more then 30 seconds to flip onto there fronts and inside the maze it can be worse. Sometimes the new 'legs' (3 of them) which are on the top of their body get lodged in the movable flags and stop vibrating altogether. It is easily possible to design mazes where the bugs never come out of the tubes upside down which corrects this problem to an extent. I have 2 Nano V2's and they both do this. Overall a great toy and all the original V1 nano track and accessories fit this new system.
