Authentic Feedback from Global Clients
Real-world experiences from buyers around the globe
We deployed the WOMI drilling rig on a geotechnical survey project in Riyadh. The rotary head torque is impressive — we drilled through hard limestone at 18 meters with no overheating issues. The hydraulic feed system maintains consistent pressure automatically, which significantly reduced operator fatigue on long shifts. The rig arrived fully assembled and tested, with all certification documents included. WOMI's technical team provided remote support during our first week of operation — response time was under 2 hours every time. Exceptional machine, exceptional service.
Second Purchase
purchased the WOMI slipform paver for a highway curb and gutter project in São Paulo. The machine's automatic grade and slope control system is incredibly accurate — we achieved consistent results across 2km of continuous pour without a single major correction. The hydraulic system is powerful and responsive, and the vibration system ensures excellent concrete consolidation. Shipping was handled professionally with full customs documentation. Our crew was up and running within a day of delivery. Best investment we've made this year."
Enterprise Clients
Bought this mini excavator for farm work and tight-space trenching. Compact size is perfect, and the attachments swap out easily. Shipped faster than expected — only 12 days to Sydney. Highly recommend WOMI to anyone looking for reliable Chinese machinery."
We've been using the WOMI forklift in our warehouse for 6 months now and it's been a game-changer. Lifts up to 3 tons with ease, the electric model runs quietly and the battery lasts a full 8-hour shift. Setup was straightforward and the team walked us through everything remotely. Shipping to Texas took just 18 days — faster than we expected. Solid machine, great value."
