My lad loves hexbugs and this extends the concept nicely and is linkable to other basic kit he has. But the tower platform is too lose and can easily be damaged (it hasn't thankfuly). So pleased with the idea but maybe this set is not the best option in this new range.
My grandchildren loved it for a few weeks but I think it's only a passing fancy. They may play with it again when the weather gets colder. It is quite therapeutic though. Arrived well within the delivery date.
