Review on 🎛️ Efficient Stepless Controller Regulator Function for CenryKay (4PCS) by Curtis Thilges

Blue light nice and bright which I like when they work. Others had a dark red light. This one is at least 20% shorter than the others so fits better and works the same as the others I've tried. Is it possible to make them reverse to the USB side? I can't connect them to the USB ports side by side because they are too tall. Every brand has this problem. Slow-mo fan or speed of a hurricane. This causes my 2 inch mini fan to blow towards me in a whirlwind, making my box fan unassuming.
