I received a couple of Ta-Tack tops a few days ago and I have been playing it this weekend.
It requires more skill than I thought. Here is a simple video in which I crack the 100-bounce club:
The main difficulty is in keeping the spin axis vertical. I'm having more success correcting it intuitively than trying to plan the corrections.
The next goal is to work on tricks.
It seems to me that the main play value is in social play where the top is passed between two or more people, more than in solo play.
It never spins very fast, so you have to be careful not to hit the body or it will easily kill the spin.
Something undeniable is that it's one of the most original tops of the last 100 years!
