Mini USB Digital Oscilloscope 5012H 2.4'' IPS LCD 500MS/s Sampling Rate 100MHz Bandwidth Support Waveform Storage Professional Handheld Oscilloscope Kit with Protective Case

It's really simple... but does exactly what you need. No complaints at all.

So far it's been perfect for my application. I ordered it for car audio to set gains and crossovers. Recently realized it's very handy for evaluating burst voltage drop on bass kicks. I have a moderately modified electrical system in my car HO alternator, 1/0 big 4. This o-scope has be super helpful in gain matching all my amplifiers. I was gonna give 4 star because i did manage to lock it up and freeze it once or twice But honestly it drives me crazy when people give poor reviews based on the fact they didn't get WAY more than what they paid for. I'm not an electrical engineer, I'm just a audio enthusiast and electronics geek. It's also proved handy diagnosing my brushless esc on my rc truck, and as well as tuning my stepper drivers on my 32bit ender 3. 100% worth the money and have used it on multiple stereo installs. I really like that i can check for clipping on every aspect of an audio system so i can tell the car owner "DO NOT turn up pass XXX or you'll damage your speakers" instead of saying "hey if it starts sounding bad turn it down. If you need a basic but reliable o-scope for occasional hobby needs this is a solid bet. The 1x/10x Test leads were also surprisingly decent.

It did not come with a manual but I googled "YEAPOOK ADS5012h" and found a very good video on how to operate this oscilloscope. It worked really well but they don't have a button labeled ENTER so that did take a little playing around. The Mode button acts as an enter mutton when changing things on the drop down screens. The probe seems to be very good, NOT an expensive, but for the price it is good. The screen has great contrast and I think I am going to really enjoy this little thing. Yes I would say it is worth the money.

The media could not be loaded.  perfect for testing moped stator

Its ok for 80ish bucks, it will get basic troubleshooting done but don't expect miracles, the usb being recessed is odd but not a deal breaker, luckily I just need it for basic testing and it will do that so we will see if it last long enough to be worth it.

Easy to use right out of the box

Ordered first one for an Arduino project. Worked well until needing recharging. USB port recessed too far into case for connection. Tried 4 different cables, none worked. Excellent Amazon customer service sent second unit, sadly it has same issue.

Nice scope for the money.

I needed something portable to check some 5V encoders at a remote location. It does the job that I bought it for.

The Mivofun Mini USB Digital Oscilloscope 5012H packs quite a bit of power in a small and affordable package.This scope comes in a nice and compact case. It is USB rechargeable and doesn’t need to be plugged in when you use it. It comes with a decent 1x/10x scope probe, and not just clip on leads.I was very surprised at how easy and intuitive it is to use. They managed to pack in full functionality with a few arrow keys. You can change both the voltage and time base values and offsets. Triggering is also well implemented. If you have used a scope before you can probably just figure it out without a manual.It was also great to see both time and voltage based selectable measurements. You can select measurements like frequency, rise time, RMS/PP voltage etc. that get displayed in real time on the screen.I threw it on the calibration port of a benchtop scope and the measurements compared closely.This is an epic portable scope. It is almost seeming too good to call it a pocket scope. This is a strong 5 stars!

Of course you're not gonna get a full on accurate scope with this,but more so a little tool to sanity check that a circuit is working the way you think. Not sure if your PWM or analog signal is doing its thing but dont care the accuracy? Then this works for you.

The triggering is a bit useless. Otherwise it works as advertised.
