content: Came across this while browsing Banggood for benchtop multimeters. Very good price. Local (AU) supplier pricing is about AU$820, whereas this converts to about AU$570. It says postage is $1 to Australia. I am happy with my Siglent for now but thought it might be good for others. It appears they have higher models also on sale.Website Description:DHO804 Digital Oscilloscope 70MHz 4 Channel 12 Bit 1.25GSa/Sec 25MPts Depth Convenient 1,000,000 wfms/s HD Touch ScreenPrice:US$ 387.99Link:https://www.banggood.com/DHO804-Digital-Oscilloscope-70MHz-4-Channel-12-Bit-1_25GSa-or-Sec-25MPts-Depth-Convenient-1,000,000-wfms-or-s-HD-Touch-Screen-p-2006738.html?cur_warehouse=CN

content: No. Nowhere on that page or images does it sayRigol. It is a DHO-804 oscilloscope, just not Rigol DHO-804.It is very important to read descriptions and datasheets for this kind of shenanigans, because otherwise you will be duped into buying replicas.

content: I wonder whether it would really be worthwhile to counterfeit an oscilloscope? Sales numbers can't bethathigh, and just producing the injection molds would be a major expense. It seems more likely to me that these are original Rigol-made scopes, but from some grey channels -- factory rejects or customer returns maybe, or units that are not meant to be sold internationally.But clearly something strange is going on. Not only did the seller avoid mentioning "Rigol" in the item description; they also edited the logo out of the main product photo. (But it is visible in the other photos.) I would not buy one of these since I would be concerned about product quality and warranty, and would certainly not expect to get warranty or support from Rigol directly.

content: (I didn't notice that you can actually see the embossed "Rigol" on the back, and the "Rigol" logo in an oblique angle in the image showing someone holding the scope. Apologies.)Quote from: ebastler on September 23, 2024, 05:12:54 amFully agreed.Quote from: ebastler on September 23, 2024, 05:12:54 amExactly.If one isn't careful, it is very easy to get caught by this kind of an ad. While we can only guess as to the reason, there must be a reason Banggood did at least attempt to remove any mention of "Rigol", so much so to edit the main product picture. It stinks of risk to me. For something like this, I'm not sure the mediocre price saving is worth the risk, but everyone chooses their own risk thresholds of course.(I just see people getting caught by this kind of "fudging", especially with open source software –– blaming the developers, and not the vendor/provider who provided the software to you with an implied promise of some sort of support –– so I want people to be sharper. Here, it is clear that very few would actually know to blame Banggood for any issues with the scope, and would instead blame Rigol. [Same with software licenses, especially with Qt. No, you don't need a commercial license to use most of Qt in a proprietary product; only if you use certain extensions/modules, or need to modify the Qt libraries themselves to work for you.] It can be exhausting to try and explain the details to people who are not used to reading stuff carefully, and just breeze through.)

content: You'll clearly get a good scope as there are already 16 positive reviews.They are just editing out the logo for whatever legal or paranoia reasons. But as mentioned, no chance of warranty. So not really worth it unless its a lot cheaper than local.
