So well. Because when I made VVTS, my skill is very limited. So maybe It make some incovinience for u to do setup. So I promise for you that the VVTS will be rebuilt one more time again and the quality will be improved so much (not be worse than VVNB and VVDN). You can have a look of review pictures about VVNB and VVDN. Expect for VVTS update is mid of next month. Thank you so much
