⭐⭐⭐⭐⭐ Alex Turner - Electrical Engineer
"I've been using the Cleqee ISDS205A Base Model for six months in field diagnostics, and it’s been a game-changer. The 20MHz bandwidth is more than enough for most industrial control systems I work on, and the spectrum analyzer integration has saved me from carrying multiple tools. The touchscreen is responsive, and the battery lasts through a full day of inspections. Highly recommend for engineers who value portability and functionality."Purchase Date: February 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Priya Patel - Electrical Engineering Student
"As a student, I was hesitant about investing in a professional oscilloscope, but the Cleqee ISDS205A has been perfect for my lab projects. The intuitive interface made learning curve almost flat—I was measuring waveforms and running FFT analysis within an hour of unboxing. The included software syncs seamlessly with my laptop, and the rugged case survived a fall from my desk without a scratch. Great value under $300."Purchase Date: September 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Jordan Lee - Electronics Hobbyist
"I use this for home prototyping and restoring vintage audio gear. The 3-in-1 functionality is fantastic—oscilloscope for signal debugging, spectrum analyzer for noise checking, and data recorder to log power supply fluctuations. The only reason I didn’t give 5 stars is that the default probes are a bit stiff, but that’s easily fixed with an upgrade. For the price, the customization potential is impressive."Purchase Date: April 2025 | Usage Period: 3 months
⭐⭐⭐⭐⭐ Maria Gonzalez - R&D Technician, IoT Startup
"We upgraded to the Advanced Model (50MHz) for our hardware team, and it’s been critical in debugging sensor signal integrity. The 2GS/s sampling rate captures glitches I used to miss with cheaper handhelds. The cloud sync feature allows us to share waveform data across teams instantly. It’s not as powerful as benchtop scopes, but for rapid prototyping and on-the-fly testing, nothing beats its portability and software flexibility."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ David Kim - Field Service Engineer
"I travel to client sites weekly, and this scope goes in my bag every time. At 800g, it’s light enough to forget it’s there until I need it. The USB-C and battery combo means I can power it from a power bank—huge for locations without outlets. The shock-resistant casing has held up through rough handling, and the display is readable even in bright sunlight. Exactly what field engineers need: tough, smart, and portable."Purchase Date: November 2024 | Usage Period: 7 months

Dr. Linda Park - Test & Measurement Consultant
"The Cleqee ISDS205A stands out in the portable test equipment space by balancing performance, durability, and usability. Its 20MHz bandwidth with 1Mpts depth is well-suited for educational and mid-tier industrial applications. I particularly appreciate the software customization options, which allow users to tailor FFT and filtering tools—rare at this price point. Ideal for training labs and field service teams needing reliable, multi-function tools."
Prof. Thomas Reed - University Lab Coordinator
"We’ve deployed 12 units of the Base Model in our electronics lab, and student feedback has been overwhelmingly positive. The intuitive UI and preloaded software reduce setup time, letting students focus on learning concepts, not button menus. The rugged design also means less damage from inexperienced handling. For educators seeking affordable, durable oscilloscopes, this is a top-tier choice."
