Review on LIUMY Professional Automatic Oscilloscope Multimeter: The Ultimate Precision Measurement Tool by Vince Preston

Check after 2 months of use. The product works fine. I wanted to give it 4.5 stars. I couldn't justify the perfect 5 stars. But for the price I give 5 stars. It's hard to replace for its value and what it does. The oscilloscope is handy, but as mentioned more of a toy. (But it worked well enough for me.) It's limited in scale and position, and sample rate. I wish the oscilloscope could be used for more than just voltage. (IE: ohms) ok you could use a resistor and a battery but that hurts. For the price it's amazing. So true. Required to check resistance of multiple parts. Used for 95m3 O2 sensor. Range of values from 0.2 to 0.8 V during full warm-up to diagnose a rich or lean condition. - Worked well enough to find my problems. My main need is an oscilloscope. However, forced to install a full test resistor (with an oscilloscope) on the TPS sensor. But even the basic resistance values worked - looking for odd readings on the oscilloscope was worth an extra hour of setup time since the oscilloscope only works with voltage. PS: keep the manual - you will need it. Once you understand this, it's easy to use. The automatic feature is nice, but slows down the reading you're looking for, so set it to manual range. SAVE the manual, like me you might forget how to set it up properly for the reading you are looking for. 5 stars for its price. But it lost a star because it's not the full featured auto tool I needed and I think it could be a better tool with a few tweaks. But the price.
