2N3055 no specific concerns but I do think about things like is the UI user friendly (having not own siglent before) I find the mso5000 a bit clunky sometimes I've also had it crash.I spent a long time chasing a signal when the scope wasn't triggering because of a bug https://youtu.be/Fg9eL_EKgmE
Aha, well those are more specific...

U/I is "inspired" with LeCroy Touchscreen concept. New Tektronix touch screen scope have similar logic.
You have menu on top, and status bar on bottom. On right you have popup vertical menu where you set parameters. When there is more data to show it pops up a larger window on the screen where you set stuff.
You simply run it as you would a tablet PC with a scope as dedicated application. Of course, there are knobs for most used stuff.
Layout is quite logical.
As for stability, in 6 months I had it I never had it crash on me. Similarly, SDS6000H12 never crashed, in a year or so.
Stability in that regard was excellent from the beginning of beta test period. There are not known bugs with triggering or like that I know of. Even if something was found it would get fixed quickly. That would have high priority.
One thing that surprises people is how acoustically quiet it is. It has fan but you wouldn't know if it weren't for a fan test on powerup.....
It is also very compact while still having large screen. Keysight 3000T has tiny screen in comparison.
Also, trace is so thin, looks like a nice trace on analog scope. Courtesy of low noise inputs and 12 bit converters.
I must say that next to powerful SDS6104H12, 3 Picoscopes and MSOX3104T, SDS2000X HD gets a lot of use....
Very nice instrument.
