This scope is great for hobby use. I would be careful if using with AC line voltages, the inner works are exposed.

This is a Rasberry Pie based unit more towards AC. The unit has DC pins, however you will have to provide leads for DC function. My only complaint is the battery goes dead if left unused for a few weeks to a month.

Is it as good as my bench scope? Hell no! But it takes up less room than a multi, and I can take readings in the field that can isolate our problems without having to set up or worry about a $2500 pro scope. I don't care if I drop it. I don't care if I drive over it. It just works. having a tiny scope like this has paid for itself over and over and saved me tens of hours in the field. They're even cheap enough that I can leave one onsite for the next guy, or in diagnostic kits at our research sites.

Nice little oscilloscope for the electronic hobbyist.

I've had a career of calibrating and repairing electronics. I bought this for home use but I was confused initially about it's settings and user functions. I began to use it on my car to chase CAN line issues. The scope had me chasing my tale because I thought my car was producing a 12V square wave on my CAN line. It turns out the user setting was set up for the X10 probe. My readings were actually 1.2 Volts. It's a rookie mistake on my part but I wish the manual and settings were more understandable. The manual does not mention anything about the many of the functions. With that, the scope is very capable and accurate but the settings must be carefully verified before beginning. Other scopes automatically change it's setting once the x10 probe is connected. This scope is not automatic in that regard but still very capable.

First, yes, we DO live in the days of miracles and wonders. After all the years that I wished I could afford a digital storage oscilloscope, here's one for a few tens of dollars. One day soon, I'll be sticking post-its to my projects, each one an oscilloscope monitoring one test point.BUT. This one really needs at least a LITTLE refinement. Note the LiPo pillow sticking out the bottom by its wires. It's apparently GLUED in that position, so every time I move this thing, I'm bumping its power leads. On the other side, the output terminals for the signal generator just stick out into the void, waiting to be shorted.As far as usability, there's a limit to how FEW controls an oscilloscope can have and still be usable, and this one seems to exceed that limit. I have, with difficulty, managed to get a waveform displayed on it. I can adjust its sweep speed, I think, with two of the buttons. I haven't yet found a way to adjust volts per division, or switch to AC coupling (maybe that's not a thing here).Given the exposed battery corner and power wiring, I'm considering this thing too delicate for routine use. I'm sure there'll come a time when it's just what I need, but for now, it's drawer-ware.Also, BEWARE of the numerous positive reviews here that refer to a COMPLETELY DIFFERENT PRODUCT, one that apparently DOES have a case and enough buttons.

I have a number of more expensive scopes but bought this just to see it. I was pleasantly surprised by the performance. I tested the bandwidth and it does indeed run up to 18 MHz - then starts to alias at 20 MHz, as expected with 40 Msps sample rate. The downside is that the unit is not in an enclosure but I have posted a pivoting enclosure design on Thingiverse so you can 3D print it.

I can't verify the frequency accuracy because I don't have a good signal generator but it is very close.As far as Ease-of-use, I just press the AUTO button and it displays a good stable signal. The only thing I haven't figured out is how to put iit into the AC input mode. It comes up in DC input.
