I’m very satisfied with the FNIRSI 2C53T Upgrade device. For this price, it offers a surprisingly wide range of features: oscilloscope, multimeter, and signal generator in a single compact unit. It’s intuitive to use, the display is clear, and it’s perfectly suited for quick tests or hobby-level electronics work.
Of course, it doesn’t replace a professional laboratory instrument, but for field use or on a home workbench, it’s an ideal choice. I can confidently recommend it to all electronics enthusiasts!
The reason I didn't give 5 stars is that the price here is somewhat higher compared to Chinese online shops, but at least the shipping was fast.
