I asked this too. I got a recommendation from a electronic newsletter about them and also found the elektor article.

They are available with a special price from banggood.com
DSO-TC3 Tester Oscilloscope
Has anyone experience with this device? Looks very promising to me. https://www.banggood.com/FNIRSI-DSO-TC3-Digital-Oscilloscope-Transistor-Tester-Function-Signal-Generator-3-in-1-Multifunction-Electronic-Component-Tester-p-1982523.html

It looks good, specially if you only want to use it for guitar pedals, because it has a low bandwidth (500kHz). The signal generator is useless for guitar pedal development though, because the range is way off (1-100 kHz). For guitar you need something in the 75-500Hz (100Hz is ok).
But it has a component tester, and checks for continuity, so that's nice to have and can replace the need to have your multi tester around. Pity the signal generator...

I think it's 1Hz to 100KHz.
100hz is below the fundamental of the low E.
That's below a drop A.
I'm a bigger fan of having dedicated tools and as I get older, prefer screens larger than 2.5 inches. It would be cool for a traveling tech or someone starting out who doesn't forsee themselves getting an actual o-scope any time soon.
But there are free audio analyzer programs out there that will be more pleasurable to use. Or. If you can procure a copy of SMAART, it's an amazing piece of kit.
If you don't have tools that already do half of these things, and don't have plans on getting dedicated tools, I think it would be a good buy.
Again. If you do a good bit of travel work, good to have in the tools bag. Buddy who does a lot of PLC automation work carries one. You don't cry when you drop it like you do with the $2k fluke.
Note, scopes.are.nice for troubleshooting and alignments/calibrations. But for design and altering filters especially,.you really want a good spectrum analyzer and a noise generator. That's where software will especially shine because hardware spectrum analyzers, or hardware driven software analyzers get pricey.
For audio, you don't need any of that though. Just a decent audio interface with a good DI input(or a decent DI)

Low E is 82.41Hz (A440 scale).

If that’s the case, then it may be a really convenient tool, given the price. It looks like a really feature rich gadget, and it’s really cheap for what it is.
My oscilloscope doesn’t have PWM (other than the square 1MHz normal to a lot of oscilloscopes for calibration), because when I bought it I was thinking more about retro computers than guitar pedals. I was thinking on changing it for the model that has PWM. But I may consider one of these instead of having to sell the old oscilloscope and buy a new one.
