I don't know, they look like the ones in the picture, they are very uncomfortable and I ordered them in brown, not black.
The product is fake and very bad, the processor is i3 and the RAM is DDR3.

FNIRSI 2C53P Touch Screen Oscilloscope | 3-in-1 Multimeter & Signal Generator
Key Features
Dual-channel capture reaches fifty megahertz. True RMS metering reads AC and DC currents accurately. Built-in DDS generator outputs twelve waveform types up to ten megahertz. Forty-eight-by-seventy-two pixel display wakes up behind tempered glass. Four thousand milliamp battery powers four hours of field work. Five languages appear instantly on the interface.
Product Description
You need faster board analysis without moving heavy boxes. The FNIRSI 2C53P oscilloscope replaces your stationary bench gear. A responsive touchscreen tracks live signals across multiple nodes. Captured traces save straight to internal memory. You can archive old patterns beside fresh fixes. High-current protection shields delicate gates during sudden spikes. You trust every measurement because four-and-a-half digits show true RMS values without guesswork. The multimeter tester handles diode checks and continuity flows smoothly. You find the electronics diagnostics path without flipping switches. The signal generator pushes clean square waves straight into amplifier inputs. You keep the portable test instrument light enough for cramped panels. Grab the digital oscilloscope before your next service call.
Product Overview
This handheld frame houses three essential tools inside one chassis. Engineers run factory line checks at packed benches. Teachers demonstrate core theories to focused students. Hobbyists prototype custom rigs without buying separate gauges. The slim footprint slips into standard tool rolls perfectly. You carry laboratory clarity anywhere you park.
Key Benefits
Stop chasing broken traces across crowded boards. Verify power rails before applying heat. Generate stable tones to stress audio circuits. Isolate weak connections during live runs. Carry zero spare cells while measuring distant units. Sleep calmly knowing your calibration stays sharp.
Features
FPGA architecture drives the analog front end cleanly. MCU logic manages the buffer cycles efficiently. ADC circuits digitize incoming pulses in real time. XY mode maps transfer curves without extra wires. Scroll view stretches time-base data across the entire screen. Auto trigger locks onto random noise automatically. FFT math splits complex bursts into clean frequency blocks.
Specifications
Analog bandwidth tops fifty megahertz. Real-time sampling reaches twenty-five hundred megasamples per second. Memory depth stores up to sixty-four kilobytes. Vertical resolution covers eight bits clearly. Time base scales from ten nanoseconds per division to ten seconds. Input impedance holds steady at one megaohm. Peak voltage tolerance survives plus-minus four hundred volts safely. Probe attenuation accepts one times and ten times ratios. DC current measures through nine point nine ninety-nine amps across four ranges. AC voltage handles up to seven hundred fifty volts reliably. Resistance reads from one hundred ninety-nine ohms to nineteen point nine nine nine megaohms. Capacitance tracks through ninety-nine point nine nine millifarads. Temperature sensors endure minus fifty-five degrees Celsius to thirteen hundred degrees. Screen diagonal measures four point three inches. Weight rests near three hundred sixty grams. Outer shell spans one fifty-four by ninety-eight by thirty-five millimeters. Power arrives via five volt two amp type-c ports.
What’s Included
One FNIRSI 2C53P main unit. Two P6100 passive measurement probes. One standard multimeter hook probe. One alligator clip attachment for clamp-style tests. One USB data transfer cable. One printed setup guide for quick orientation.
How to Use
Attach the black ground lead to the common reference point first. Clip the red tip directly to your target node. Tap the on-screen menus to toggle between voltage, resistance, or waveform views. Rotate the control knob until the pattern fills the grid evenly. Press the capture button to freeze moving traces. Swap leads whenever shifting between high-voltage mains and low-voltage logic lines. Store finished tests inside the built-in drive before shutting down.
Customer Benefits
Your repair routine speeds up noticeably. Fewer false jumps mean less scrapped hardware. The rechargeable cell works hard hours away from wall outlets. Glass touches respond instantly during warm afternoons. Archived snapshots upload straight to shared project folders.
Ideal Uses
Diagnose motor controller faults in garage gear. Map amplifier gain stages inside studio mixers. Validate sensor outputs on drone airframes. Trace hidden leaks in vintage radio sets. Run automated burn-in checks along assembly lines.
Who It’s For
Field technicians handling urgent service calls. R&D builders drafting custom prototypes. Classroom instructors proving fundamental physics. DIY makers fixing household appliances. Quality managers verifying production checkpoints.

I used it to test components on my bose amp. very consistent results, good medium fine probes, pvc coated but reasonably flexible. was able to determine board issue. easy to use. some limitations so use within its spec ranges. need to test oscilloscope and signal generator.
R
It seems to be a good piece of equipment to start with, it has the precise functions needed to measure basic and moderately complex circuits. The probes are good, a good price/quality ratio. I will put it to use and expand my opinion. It has a good size for carrying around in the field, and comes with its own bag to transport it along with all its accessories. It's fine 👍.

Excellent service and products

packaging+, (factory condition in perfect condition), device+, (there are some nuances, like 3 in 1 - excellent, compact device, generator - excellent, tester - excellent, oscilloscope not great but signals can be viewed on 4. There is a caveat upon receipt: you need to reflash to version 1.8, otherwise the generator resets settings in oscilloscope mode.

a beauty

Nice packaging, a small oscilloscope tablet, wave generator, and voltmeter. However, in terms of measurements, they are completely inoperable, especially the oscilloscope, which makes it impossible to adjust the probes after communication and videos proving the false values indicated by the oscilloscope with the seller and customer service. It is necessary to change elements in the device's PCB, which I refused to do myself. I need an operational oscilloscope, not a DIY one. I find that the manufacturer has made a high-priced gadget without quality control before putting this product on sale. I do not recommend this product to future buyers; either buy the higher-end model or, as a reminder, I bought this product twice and had the same problem both times. A disappointing experience. waste of time. I am disappointed. 😔 😔 😔 👎 👎

It arrived super fast
G
Very good product, meets all expectations, recommended.
J
Very good, arrived well packaged
C
For the price and as my first piece of equipment, I think it meets all expectations. I like it 100 points.
V
Hello! I am not satisfied with the oscilloscope because the waveform is not displayed, and the problem is specifically with the oscilloscope itself, as I tested the probes on another oscilloscope.
H
The device arrived with a defect. The generator only generates a square wave signal. You can go to the generator settings, change the signal shape, frequency, voltage, and fill level, but when you re-enter the oscilloscope, the generator switches back to a square wave, 3V, 50% fill, frequency 1kHz. No matter what I do, the values do not change!
K
Great item if the battery lasted
F
Received it, checked it, everything works, bought it for non-professional use, for a home workshop. The specifications of the device and the included accessories are satisfactory. I liked that the oscilloscope comes with a case. The seller shipped everything very quickly.
B
everything looks good, seems to be of very good quality
A
Arrived quickly, device of good quality and practical.
G
Very beautiful, many functions, good screen, but... as an oscilloscope, it's not suitable. It displays low-frequency signals incorrectly. The photo shows an example of what a low-frequency periodic signal looks like. That is, there are glitches in the measurements (digitalization), making such an oscilloscope of little use. Synchronization also has issues. I should have looked at reviews before buying...
