And like the OP said, these Owons scopes are priced in same price range with the likes of Siglent that makes fully professional gear.

Well, there are Owons and Hanmateks in the same price range, but they hardly ever appear in online forums.

You can even get a 4-channel Hanmatek for <$200

There must be other reasons that give a device "momentum" (or not).

Well, those are all 8 bit scopes. The one in the first link lists at € 224 + € 81 shipping. Not interesting at all.

The second is € 164 including shipping for the 2 ch version. Might be an interesting alternative to the Owon HDS scope meters, but that's it.

My question basically was whether the 14 bit Owons offer any real advantage over the 12 bit Rigols and Siglents. I found this, which is an older review of one of the earlier and pricier 14 bit scopes from Owon. It is superficial in that Dave talks about menues and display options. There is one sequence with a breathing waveform, but it does not become clear if that is user error or a fundamental problem. We never get to know if the performance lives up to the promises (I would assume not after reading some more):

Can't find it now, but there was a noise comparison between the OWON 12 bit and the new DHO800 in one of the DHO threads. The Owon actually had better noise characteristics at lower frequencies, if I remember well. However, it costs around the same, has less bandwith, sample rate, less memory depth, worse screen, no support, is thicker, doesn't have VESA mount or HDMI out, has a tiny fraction of the features, etc. The SDS800X-HD is even better in everything except screen, form factor and I/O, and they are the same price, and even cheaper for 2 channel models.
There is just no contest.

Owon doesn't lie like Fnirsi...
The OP should not forget that the Owon 12-14 bit is not at the maximum sampling rate!
8 bits -1Gs, 12 bits 500Ms and 14 bits 100Ms...
Siglent and Rigol, on the other hand, know 12 bits at a speed of 1.25Gs or 2Gs.
As far as I know, the memory depth also changes if you use Owon in 12 or 14 bits. Now I couldn't find in his description, to what extent.

I already answered you. Are you going to repeat question until you hear what you want?.

These Owon 14 bit scopes are not good, and that is it. If they were priced at 200€ people would buy them.
And you are wrong. Here on EEVBLOG people already asked this question, and few people bought one and were disappointed how limited device was and how badly it performed.
One member managed to use it as a sampler (pulling data to PC) but had problems with slow and unreliable transfer.
Also, although it uses 14bit ADC, it's preamp is not very good, and he managed to get good data only on some input ranges.

If these scopes were diamond in the rough, you can bet that they would sell like hot cakes. It doesn't need much to spread a word.

And with real, proper 12 bit scopes from good brands starting now in 300€ ranges, these cheap brands will make even less sense.

Unless they pick up their game and start making better products, or drop prices even more..
Which is good news both ways, for people short on money.

But as for now, avoid if you can.

I think Eddie, from the Kiss analog YouTube channel has one, there are a couple videos in which he uses it. Maybe you can have a look there.

Thanks, found it. That's exactly what my question was about. I only wish there was a test of the newer models.

But by now, I am pretty convinced to stay away from Owon. Just one more Siglent / Rigol question: why do people keep saying the Rigols have nicer screens? I get that for the 10" models, where Rigol offers 1280x800 vs. 1024x600, but for the small ones, Siglent offers a wider screen and more horizontal pixels. Does it have poor viewing angles, is that the issue? Or is this about the two pixel height thing in the Siglents?
