Nothing to feel sorry about, I’ve paid nothing so I can demand nothing 
How can I select less then 0,2V/div? And you have to adjust the speed of moving things on the Y axis so the longer you press the faster it moves (acceleration) or someone will have a nervous breakdown 
Also you can’t add a half a dollar more on those red and black hooking grip connectors? Mine broke directly, not so badly but by connecting it to the hook on the probe was bent enough so it will not retract fully again. These makes the product look stupidly cheap, they are simply not in the same division as the rest of the kit.
