🏗️ Construction Site Engineer Reviews

⭐⭐⭐⭐⭐ James Carter - Senior Site Engineer, Infrastructure Projects
"We bought the Pro Model for on-site quality control during bridge reinforcement work. The 650kN capacity handles even the heaviest-grade rebar effortlessly. What impressed me most was the AI-driven adaptive testing—it adjusts parameters in real time based on material response, which is invaluable when dealing with variable batch quality. Setup was smooth thanks to the included training session."

🏭 Manufacturing Quality Control Reviews

⭐⭐⭐⭐☆ Lin Zhao - QC Manager, Steel Fabrication Plant
"Reliable and robust. The adjustable clamping system works perfectly across our range of 12mm–45mm steel bars. We process high volumes daily, and the machine keeps up without overheating or accuracy drift. Only reason I’m not giving 5 stars is that the 380V requirement meant we had to install a dedicated line—would love a dual-voltage option in future models."
