The scope does what it is supposed to, you get a time-domain 
visualization of voltage.
Though, they are awkward to use due to the lack of rotary encoders.  
Scaling horizontally or vertically requires you to go into a menu, 
navigate to the right option, do the actual scaling and go back.
It's better than no scope at all, but not exactly the model you'd hunt.
