This could be a fun gadget for that price but it does have to have a decent level of reliability and trustworthiness.
I am more interested in a Siglent for anything serious, but still consider buying something like this just for shits and giggles or for hacking into. But some level of trustworthiness is still mandatory. The Fnirsi garbage for example does not do that, because it blatantly lies about it's specifications, and on top of that tries to hide this by always dong some weird averaging on the signal. That thing is just horrible.
This is all the more important because gadgets like this are targeted to the beginners market, and those beginners don't have the skills to interpret the limits and recognize the faults. I'm guessing fnirsi relies on that, and that makes them sneaky bastards all the more.
This thing also does not start well in that regard.
What does a "Sampling rate: 50M/Channels" mean?
And a bit lower, it suggests an "Actual bandwidth" of 2MSa/S/Channels, which could be interpreted as 1Msps if both channels are on.
But "Analog bandwidth" also uses "10MSa/S/Channels".
And someone should tell them that seconds is a lower case s, Upper case "S" is for Siemens, which does not make sense in this context.
To me it's a lot of Chinglish that adds to the confusion.
But still, I'd like to see thorough review, including a teardown of this thing. Especially if it has a half decent analog frontend. But even if it is decent, it is unlikely that I would buy one. It is the lack of a rotary button that does it for me. I'm addicted to rotary buttons. I have bought the "DSO Shell", (which does have a rotary button) and I would have liked it if it had better triggering.
