30-minute express on-site device rescue across Zhengzhou's core districts, with transparent work in front of you
In today's fast-paced working life, digital devices such as smartphones and laptops are indispensable productivity tools. When a screen shatters, a swollen battery stops the device powering on, the system stutters or blue-screens, or the office network and broadband go down, carrying the device through wind and rain to a physical store in Buynow (Bainaohui) costs time and effort - and can cost you valuable business opportunities along the way.
Traditional on-site repair is plagued by invented charges, wildly inflated prices and parts swapped behind your back.Fengniu Tech (Henan) So we launched a high-quality express on-site repair service for local customers. Inside Zhengzhou's urban area (including Jinshui, Guancheng, Zhongyuan, Erqi and Huiji districts and Zhengdong New District) we respond within 30 minutes and arrive with a professional instrument case. Our engineers diagnose and disassemble the device right at your desk, in front of you, with transparent pricing - and if they cannot fix it, every call-out, labour and inspection fee is waived. It is a safe, worry-free local service.

Fengniu Tech's three ironclad guarantees
1. No labour charge if we cannot fix it: If, after inspecting the device on site, the mainboard is judged to have been burnt out by high voltage and beyond economic repair, or you decide not to go ahead because our parts quote is not worthwhile, we guarantee [no call-out fee, no labour fee and no diagnostic fee], so you have nothing to lose.
2. Full compensation for damage: If an error by our engineers during on-site teardown or replacement causes secondary, irreversible damage to your device, we will buy the device back in full at its pre-repair condition, or compensate you with a device of equivalent condition.
3. 180-day extended warranty with free return visits: Every part we replace on site carries a warranty of up to 180 days. If a fault appears during that period for reasons unrelated to user damage, just call us again and we will send an engineer back to your door free of charge to put it right - with no travel on your part at all.
Local On-Site Repair FAQ
Fengniu Tech has always stood for honesty and good faith. Our on-site service strictly follows the standard of no labour charge if we cannot fix it. If, after inspecting the device, an engineer judges the fault to be irreparable physical damage (such as a core CPU burnt right through), or you decide not to proceed at our quoted parts price, we [waive all call-out, labour and inspection fees]. A repair fee is charged only when the device has been successfully fixed and powers on and runs normally.
[You can set your mind completely at rest!] First, our engineers always work openly in front of you (at your desk or in your home), and you can watch every screw being removed and refitted. Second, Fengniu Tech has extremely strict staff privacy and security responsibilities: before the visit we confirm the device's power state with you and scan and record the serial numbers of the main components, and we undertake to bear full legal liability for any data leak.
Every high-quality, original-specification part we replace during an on-site repair carries the same 180-day extended warranty as in-store repairs. If it fails during the warranty period for reasons unrelated to user damage, simply call us again and we will send an engineer back to you free of charge to put it right - no need to travel back and forth to the store!
Fengniu Tech's on-site repair service covers the whole of Zhengzhou's urban area (including Jinshui, Erqi, Zhongyuan, Guancheng and Huiji districts and the core of Zhengdong New District).
