I remember trying to get the spin faster/slower, stopping the spring, etc.
Since it required no batteries it was always working, even when you found it at the bottom of toy bin after months/years.
This modern version is a complete scam, especially since the outside look seems absolutely identical to the original. I'd be very disappointed if I bought one for a toddler, only to realize when unboxing it's crap.
By the way, we still have the original toy from my childhood. It's been passed around to relatives, but last I heard, it still works after what must be almost 40 years.
