I wasn't sure what to expect from this, but it has become and indispensable addition to my workbench. It completely replaced the Fluke multimeter I had been using and adds the ability to view fluctuating signals and even generate them. Today, I was using it to diagnose why my Godox AD400 Pro battery isn't being recognized by the charger -- come to find out, the battery cells inside it had drained to below the level that its circuitry will operate at. Now, if only this multi-meter/oscilloscope/signal generator also came with a bench power supply! Just kidding... sort of.
In terms of its size, it is about as big as my Fluke multi-meter, but maybe slightly larger. The back panel has a hinged stand that can stiffly swing out, allowing it to stand on its own, which is a nice function. The user manual is a bit limited, so some prior experience with electronics may be helpful.
The accuracy seems just as good as any other multi-meter. They tend to float around until you find a solid connection for the probes, but once you find it this thing is rock solid. I'm really glad I've got this.
