FNIRSI 2C23T 3 in 1 Handheld Oscilloscope Multimeter DDS Generator, 2 Channels, 10MHz Bandwidth, 50MSa/s Sampling Rate, 10000 Counts, Voltage, Current, Capacitor, Resistor, Diode Test: desertcart.com: Tools & Home Improvement

Review: Exceptional Performance and Outstanding Customer Service - I recently purchased the FNIRSI 2C23T 3 in 1 Handheld Oscilloscope Multimeter DDS Generator and I must say, it has exceeded all my expectations. This versatile tool, with its 2 channels and 10MHz bandwidth, coupled with a 50MSa/s sampling rate, has made my electrical measurements and diagnostics tasks remarkably efficient and accurate. The 10000 count multimeter functionality is a bonus, seamlessly integrating voltage, current, capacitor, resistor, and diode testing capabilities into one compact device. But what truly sets this product apart is the outstanding customer service I experienced. Upon realizing that an oscilloscope probe was missing from my package, I contacted their support team. Not only did they respond promptly and courteously, but they also exceeded my expectations by immediately sending the missing probe. To my surprise and delight, they included a free tiny oscilloscope as a goodwill gesture. This level of customer care is rare and truly appreciated. The device itself is user-friendly, robust, and reliable, making it an essential tool for professionals and hobbyists alike. Its intuitive interface and crisp display add to the overall user experience. The accuracy and range of measurements it offers are comparable to more expensive models in the market, making it a cost-effective solution for a wide range of electrical testing needs. In conclusion, the FNIRSI 2C23T is not just a high-quality product, but it's backed by a company that genuinely cares about its customers. Their prompt and generous response to my issue has earned them a loyal customer. I highly recommend this product to anyone in need of a reliable and versatile electrical testing tool. Five stars well-deserved!
Review: Initial problem solved, excellent little scope. - I am revising this review as it “was me” sort of. It occurred to me after posting a somewhat negative review that possibly something was wrong and “floating“ with the probe. On careful inspection I noticed when trying some DC voltages that odd things were happening as I moved around probing different points. Using a clip cord instead of the supplied little jumper for the “negative“ my problem disappeared. Then, of course, I measured some AC with the clip cord and voilà problem solved 120 VAC was measuring reliably 338 V peak to peak. Which is more than close enough for me for the price of this little scope. On close inspection, the little clip cord for the probe was broken at the alligator clip end. Replacing it with a new clip, solve the problem. Further, the seller reached out to me to rectify the problem after I posted the review. My original review : I don’t think it is me, but…. Didn’t really get around to trying this thing out for a couple of months. Bought it mostly as my 40 year-old Tektronix gave up the smoke, and I use/need a scope every 5 years at most. Presently I had bought it as I wondered about the waveform (ends up pretty poor) from my whole house Generac guardian generator. So this little scope is convenient as heck, but unfortunately shows only 196 to 200 V peak to peak reading my 120 V RMS generator, or a on a quality solar generator it’s only reading 185-190, or on line power 190-195. So although I am super impressed by the display, reasonably impressed by the functionality, for actual AC measurement, it seems pretty useless. Several calibration trials didn’t seem to make any difference. Perhaps I will see if there is a firmware update. On the multimeter, no problems whatsoever. 120 V RMS is 120 V RMS.

### ⭐⭐⭐⭐⭐ Excellent value
*by A***R on April 21, 2026*

Works well in small cramped areas as second oscilloscope. Portable. Multimeter is excellent. Component tester works great. Signal generator produces multiple dc signals. Oscilloscope works well, only quirk is it defaults to ac coupling when auto button is pressed, could likely be fixed by a future software hopefully. Slightly confusing UI. But great value for money.
