90mm head SST50, 3x 18650s.

I think the main reason a lot of people hold back on the TF X6 is because the SST90 is underdriven quite badly, I don’t remember how much but I remember it being not that high.

yes i remember seeing videos on youtube and it is underdriven. but let me tell you guys, it can still throw like a beast. outthrows my king for sure. less than the tk70 though.

SST-90 are nice !!! Here is my first beamshot with the ST-90
