Picoscope 7 software example:

I cannot speak as to what someone else meant, but I do know that variable res Picos (5444D for instance) in 16 bit mode don't approach dedicated 16 bit scope ENOB. Also even in 12 bit mode they have max sampling rate of 500 MS/s, that drops to 125 MS/s at 3+ channels used.
Compare that to 12 bit scopes we are talking about here that will sample at worst case of 500MS/s and up to 2GS/s for cheapest SDS800XHD.
Comparisons should be like for like.
Of course a person can have simple needs and only priority could be, for instance, maximum BW. In which case you go get that at cheapest price and disregard resolution, math, measurements, statistics, bode, and all kinds of other analysis options.
But if we are comparing, that "high BW and nothing else" scope is NOT the same as the one with full analysis options and capabilities.
So if more advanced scope is much more expensive you make a decision to not pay for stuff you don't need and will never use and get simple high BW scope.
Or if price difference is not much, you get better scope, even if you don't have immediate plans to use all of that. But it doesn't hurt to have more capability and who know maybe you will learn that it might be useful to you after all. If you can afford it, of course.

What legal matters?

1st to mind: selling devices intended only for Chinese market to the outside. Don't say it's not a problem for the buyer, as I never said that.

hi Mechatrommer,

thanks for presenting the prices in Euro...
In Malaysia, you may buy thru tabao & get these scope @ chinese prices.
In Europe (I guess in any western country), the custom will put the parcel aside, and prepare the bill to pay the duties... and if we don't pay this extra, the custom will keep this lovely scope. Hown much is this "extra" ? I don't know, but the final price will be far from your figures !
It's pretty much like viewing a nice waveform on scope... but voltage is wrong because you set an attenuation 100:1 with your 10:1 probe ! :)
Thanks anyway.
But I prefer to wait for the real prices from local resellers
Nice new year's eve to everyone ! :-+

But then you are assuming it is a problem for the seller without actually knowing making it speculation based on arbitrary assumptions.
I mean I agree with you that comparing prices from Taobao to what is available makes no sense due to the effort and risk in buying that item (risk being, getting a brick instead of an item, getting something else, not getting the item, warranty claims, list goes on).
But legally from the buyer there is no problem, I can write a blog post about this but in the western world you'll make more progress hammering your head against a wall than trying to restrict a market and defending that in a court case.
And legally from the seller's persective that is none of our business. Even if Siglent aren't happy with it, that isn't something they need to make our problem, that is their problem.

In europe there is just no defense for a company trying to forbid or punish a customer for buying anything, anywhere, as long as it's not a legally forbidden/restricted good.
That being said, not having legal coverage for warranty, returns or support, or legal standing to try and enforce it is a legal problem. It's not "problems with the law", though.
Probably just linguistics.
