anyone fast at transforming/change gimmicks in kr/sentai
 

for example: i was watching kyoryuger cardinal/snapping changes episode with the zord arms and daigo was changing out the batteries really fast to transform into kyoryured cardinal samba/western/maccho/kung fu forms.

im assuming some kids/adults in japan can do it that fast while watching the program with their Gabutyra DeCarnival toys.

my point is, is anyone fast on transforming mechas/changing forms on kr/sentai while watching the program or doing it on your own without it? if so what toy/sentai/kr season can you do it on?
