【8FLIGHT】Haruki Muramatsu Model G2 Slim MIX 's Japan Review

This is the first time I purchased an ∞ flight.
I used to have to use a lot of force to insert the flight into the shaft, but this is a breeze because you just turn it like a screw.
It doesn't loosen at all when I use it, but it doesn't bother me.
I will continue to use it.
