I can get past the lack of any useful documentation/instructions, pain getting the software and drivers to work in x64 Win7 or Win8 but the unstable software and hardware were too much.  The scope software would intermittently drop out the USB connection/communication to the scope hardware module regularly on ~3 min intervals after about 10 mins of operation.  I tested on two separate computers one with Win8 and one with Win7 with same behaviors.  It only seemed to work fine for measuring low voltage square waves.  The main reason I wanted this unit was for secondary ignition waveforms and it did not work at all for this usage scenario.  Upon connecting the supplied BNC HT ignition probe to any secondary ignition cable, the software would not display a waveform, it would and say it was searching for a signal and sometime it would even crash the computer OS.  My guess is a driver issue - I did however download whatever I could glean as being the latest drivers from Hantek's web site and also checked their support bulletin boards.  Very disappointing overall experience as I wasted a good bit of time trying to get it working.  The only upside is Amazon stood behind the product and processed a return for me.  I understand that one can't expect much for something priced this low but I'd expect it to at least work for the most basic functions its advertised as supporting.  The only thing I didn't try is setting up an XP SP3 OS build to test on.
