Hi Wong, I have received the 2 tubes (1 x silver and 1 x red) tried for few games and I am so happy with it. The silver doesn't last long as the red ones but certainly the durability, speed and accuracy is similar to protech, rcl, yonex and whatnot in the range of RM50+ which I have been using for many years.

You certainly save few bucks in my pocket. Thank you. I will order again shortly.
