I can't comment with any experience on the Owon. I do have an Owon signal generator - bought because it was cheap and Amazon Prime, etc. It has an annoying issue with the main rotary controller being noisy, so I'll often get gaps in settings... e.g. 1..2..3..6..7..8, and sometimes jumps or (annoyingly reverse jumps) e.g. 3..4..5..2..3..4..5..6.

I've not read that about their scopes - and I imagine all their gear is likely just rebadged from the Chinese Factory.

Reviews (Elektor) are generally in praise, my concern would be for weak trigger patterns (e.g. on mine, I often use a gated-window trigger to trigger on noise spike signals that exceed a threshold for less than e.g. 100uS - ignoring longer "intended" pulses) and no apparent protocol decoding (yes, I've used a scope to monitor packet values in both serial/RS232 and IIC busses before now). But, at the price you can pick these up for (~£170) you get a lot for your money.

Ultimately I expect you'll get what is advertised - just make sure that it ticks your boxes. At £170 or so it won't owe you too much over time.

I'm almost waiting for someone to suggest buying a second-hand "high end" scope - and I've looked at this option myself - but to be honest, these new scope-on-a-chip solutions beat the older technology hands-down on bags-per-buck provided that you don't need the instrumentation-level precision of the big boys.
