Small but powerful!
Size: DHO804
Awesome little oscilloscope with so many features that I have no idea how they work. I am an no electronics expert by any means so I can't comment on accuracy but this machine is well built and the display is very clear and easy to use. Package comes with several probes to suit your objectives and this oscilloscope can even be hacked to provide the same features of the heigher models which is nice to know, however I would not advise to do it as it will void warranty. In any case, for those in the electrpnocs hobby, this is a high end item and has a small footprint.

Great scope/great value
Size: DHO804
This is my second oscilloscope. My first was a "starter" scope, which worked OK and did the job. But it only had two channels, and I needed more. Then came the Rigol DHO804 whose price was surprisingly low with a very solid reputation. The Rigol is clearly a next-level class of scope. This shows up in the relative absence of lock-ups (not that they aren't reported to have some), the accuracy of the lower millivolt measurements, and the general sturdiness/stability of the physical and software qualities of the scope. There's a lot going on in this scope, and it works as expected. One significant value point is that the scope's software uses Android as its operating system. Combined with the touch screen which works well, the user interface is clean and sophisticated. For example, it presents transparent dialog boxes in which you can change settings (in the foreground) while watching how that affects the display output (which is transparently visible in the background behind the dialog box). Nice! Though this scope is limited to 70Mhz input bandwidth, aside from that limitation, it appears to use pretty much the same software and UI as Rigol's faster, more expensive scopes. So as long as that upper bound of frequency is acceptable, you get almost all the features and functionality you'll see in higher-end scopes. It feels like a professional scope. Another great feature is that the scope has a built-in web interface that serves up a remote-control window in your web browser. This lets me take full control of the scope UI using my laptop. The remote display is quite responsive (not laggy at all). I plugged a USB wifi adapter into the Rigol (instructions for this are out on the web), and the whole wireless remote setup fell right into place. By using the remote UI, fine tuning the scope and saving/naming screenshots is a snap. This is a great scope, and a great value. Unless you are a professional with prior experience and a need for a particular functionality not provided by this scope, you will not be dissatisfied. It's a very tight, very well made, very capable package.

Great for the price

Solid scope for the price. Really nice quality and easy too use. Not sure if setting can be saved from use to use.

Good scope, reasonable price… you get what you pay for plus a bit more.
Size: DHO804
This is a solid workhorse scope for many practical applications for entry to intermediate level use. My personal use cases for this scope are audio (including synthesizers and other generated audio), and HF ham radio. For these purposes, 70mhz is perfectly adequate. Having 4 channels adds a great deal of utility. The controls have a slightly different arrangement than many other brands, but have the same essential functionality. These differences are mostly in the knob and button controls and their orientation. Menus are similar to how other brands are arranged with any differences only being minor. I have only worked with FFT in the math, and had success doing basic frequency analysis. Doing that and basic scope functions let me play with resolutions and scaling functions. Both horizontal and vertical adjustments work as expected and I was able to get useful visualizations and data. The package size and layout is great for my purposes, big enough to easily use, small enough to set up in a wide range of work areas. The screen is easy to read and presents cleanly. You can hook this to a larger monitor through the HDMI interface, but you do not have any visual resolution advantage. I will likely continue using just the built in screen, only. All in all, a practical scope at a reasonable price. It will be great for troubleshooting, signal tracing, as well as basic equipment calibrating.

Excellent scope. Great features and speed.
Size: DHO804
Design: Rigol definitely stepped their game up this time. I've been using mostly Siglent due to better interface. Not this time. Rigol cleaned up the front panel, moved a lot of features into intuitive touch-screen menus. Hardware: Overall I feel like this is a pretty big leap over their older scopes in this price segment. This scope is basically an android tablet. It is tiny, gets powered by a USB-C power supply. Hardware is very power-efficient. Screen is responsive and precise. Probes are standard cheap BNC type. Perfectly adequate for 70MHz. Accuracy: For the price it is very good. The added resolution is nice, but I wouldn't say it's a game changer. I just don't work with that level precision in my garage. Triggering is still razor sharp. I heard there is a way to upgrade memory depth, which I guess could be very helpful if you're trying to catch a longer signal. Acquires AM and FM waves very accurately in AC-coupling mode. Functionality: It has all of the math features that you'd need. The FFT is blazing fast. This truly feels like a generational leap compared to last gen. Word on the block is that Rigol is using a custom ASIC to achieve such speeds. Areas to improve: I think the physical interface could be improved even more. Rigol does their typical Rigol thing with using different fonts around the panel. The included probe color rings don't match CH4. Honestly, the touch screen is so good that I would just consider using a 10" display and removing physical controls for the next iteration.

Very Nice
Size: DHO804
My only minor complaint so far is the quiet but noticeable fan whine, which has a pitch to it. I had read about that before I bought it, so I cannot fairly take any star off for that. The last scope I bought was in 1994, which was a brand new 20 MHz Kenwood 2 channel, analog (of course), for almost exactly the same as I paid for this. I still have it and still use it. Still works perfectly, minus the slightly faded phosphor. Adjusted for inflation, this Rigol DHO804 has like, I don't know, 1000 times the features and capabilities, for half the price. So like, what am I going to complain about? For me it's like going from a Commodore 64 to an M1 MacBook. That makes this not a completely apple-to-apples fair review. Skipping all the crazy awesome bells and whistles (to me), in practice, the nicest thing about this new scope is that I can situate it anywhere on or around my desk, or mount it on the wall, or an articulating vesa arm. That alone is worth the price of the upgrade.

Cannot send screenshot to PC
Size: DHO804
Rigol doc falsely claims you can send a screenshot to a pc folder over ethernet cable. i wasted hours on that. it wants user to install "ultra sigma" on pc which is rigol proprietary bull-pucky, 11 years old obsolete and looks it. you have to install old .net libraries. even then it doesn't work. also, i don't have free usb port on pc. so i have to take a photo of the screen with my phone, which has lens losses and screen reflections. i manually force google Photos to upload it. then on pc i have to browse to the image in Photos and download it. what a hassle! Rigol should support some wireless protocol to pc for this, with no proprietary app.
