Bad Siglent 1102X?

[Bob Sava]

As I'm waiting for my scope to arrive I've been looking through youtube videos (even in other languages....) and found one about SDS1202x-e cousin, SDS1102X which I believe is based on the same software. 

@8:25 SDS1202X is the only scope not showing square wave accurately (as compared to other three)

Any ideas why?

Who knows which one is accurate ? 

The only way to compare apples with apples is with BNC cable connection so the exact same signal gets to the inputs and all the different probes aren't taken into the equation.
