Authentic User Feedback

🔬 Laboratory User Reviews

⭐⭐⭐⭐⭐ Dr. Alan Foster - Electronics Research Lab
"The ETA5380 Pro Model has transformed our signal analysis workflow. With its 20MHz bandwidth, we're now capturing fast transient currents in switching power supplies that our old 10MHz probe completely missed. The ±1.5% accuracy gives us confidence in every measurement. Integration with our oscilloscope was seamless, and the lightweight plastic body makes handling during extended testing sessions effortless. After 5 months of daily use, it shows no signs of wear."

⚙️ Industrial Maintenance Technician Reviews

⭐⭐⭐⭐⭐ James Wilkins - Power Systems Maintenance Engineer
"I’ve used current probes for over a decade, and the ETA5380 is one of the most reliable I’ve worked with. We needed something that could handle 80A continuous current in our substation monitoring setup—this delivers without overheating. The plastic housing is a game-changer: it’s lightweight, doesn’t corrode in humid environments, and provides excellent electrical insulation. Safety certifications (CE/RoHS) were a must for our site, and this checks all boxes. Installed in under 10 minutes thanks to the compact test loop design."

🛠️ Home Workshop Enthusiast Reviews

⭐⭐⭐⭐☆ Priya Mehta - DIY Electronics Hobbyist
"As someone working on small-scale power electronics at home, I was skeptical a professional-grade probe like this would be overkill. But after building a few SMPS circuits, I realized I needed better diagnostics. The ETA5380’s high-frequency response lets me see ringing and switching losses clearly on my scope. It’s surprisingly easy to use—just clamp around the conductor. The only reason I didn’t give 5 stars is the price, but considering its precision and build quality, it’s justified. Already planning to get the custom labeling option for my lab setup."

🚘 EV Prototyping Team Review

⭐⭐⭐⭐⭐ Team Lead, EV Systems Lab - University R&D Group
"We’re developing motor control units for electric vehicles, and precise current monitoring is critical. The Pro Model’s 20MHz bandwidth allows us to analyze high-speed switching in MOSFETs with exceptional clarity—33% faster signal capture than our previous probe, just as the specs claimed. We customized the mounting brackets to fit our test rig, and the modular design made integration smooth. After 6 months of heavy use in a noisy lab environment, it still performs like new. This isn’t just a tool—it’s a precision instrument."

🔌 Field Service Engineer Review

⭐⭐⭐⭐☆ David Chen - Field Diagnostics Technician
"I travel to industrial sites weekly, troubleshooting motor drives and inverters. The compact, rugged design of the ETA5380 fits perfectly in my toolkit. It’s survived drops, temperature swings, and dusty conditions—all while delivering consistent readings up to 80A. Cleaning is a breeze with just a damp cloth, and the non-conductive plastic body gives me peace of mind when probing live circuits. My only suggestion? Include a protective case in the Pro bundle. Otherwise, outstanding performance for real-world fieldwork."
