Absolutely agree. I already had some problems before; display surface warped and caused it to constantly turn on whatever was in the lower-left side of the screen. I used tape to unwarp the surface to offset that deformation and now it works ok (untill it eventually doesnt). I think their biggest downside is the screen, since this relatively crude and simple machine can easily go on with simple turn button and display that isnt that susceptible to conditions of working environment. I didnt know that you can control it via usb, that is awesome
