Great piece to work with.Touch quality is really good.using it for a while now but no any major issues.other than the slight noise from the fan everything works well and good.Though the fan noise can be ignored, it is a bit annoying.considering the money that we pay for this piece it is worth the money.
As mentioned above touch quality is too good as of my knowledge. Not even a single problem in the matter of touch response.It is worth the money.
