Tried the Viper for a couple of days now, and i am disapointed :(
Had a Boomslang and liked it a lot for the 6 months i lasted.
I use a SteelPad 4s and the viper seems to work ok, but as soon u make a quick movement the viper looses track and the pointer doesn't follow :(
I also tried the Viper on a Steelpad 4d (which is hard plastic, with a smooth and rough side), here the same thing happend on the smooth side...the pad is to smooth or shiny, the vipers optics r just not good enough, the arrow cant keep up if u move your hand to fast!!! On the rough side of the Steelpad 4d it worked fine.
So if u use the SteelPad 4s or the smooth side of the steelpad 4D you dont want to get a Viper!
