You've read this, right?

If you get one, I hope you'll bring it by a Monday meetup. I'm really
curious to see it. There's so little info about this scope, like
whether it does intensity grading and how many waveforms/sec it
captures, if it does. Reply #8 on that thread claims to have more info,
but I can't see where he got it, and it doesn't make much sense to me
either. He believes it captures 2000 waveforms/sec, but the he says
there's no intensity grading, which doesn't make much sense to me. I do
not believe any TFT LCD is that fast, so how could 2000 waveform/sec
work without rendering to intensity grading? But this page has a number
of screenshots that look like they might be intensity graded?

But those screenshots look nothing like the images on the product
photos, which look less like photos and more like illustrations (gray in
the illustration/photo, bright blue in the screenshot). I couldn't find
anything that looks like a real photo of this scope actually in
operation, other than a splash screen, not the 'scope's actual waveform
display. So much mystery!
If $500 is a lot of money for you, I'd recommend waiting. Early
adopters can really suffer, especially with brands like Hantek.
