Frequently Asked Questions
Who makes YCS microscopes — is the 6558S a genuine YCS product?
YCS (Repair Master) is the tool brand built around Mr. Yang, one of the best-known repair educators in the phone repair community. Vexagoo is an authorized distributor of QianLi and YCS repair tools, so every 6558S is factory-genuine with full warranty support.
How is the YCS 6558S different from the QianLi 6558 Gorilla?
Both are trinocular stereo zoom microscopes from the same 6558 optical ecosystem. The Gorilla covers a wider 3.5X–90X range and is the high-magnification flagship; the 6558S covers 6.5X–58X at a friendlier price and includes the CTV 0.5x camera adapter and a limiter ring in the box. See the full side-by-side in our Gorilla vs 6558S comparison.
What does the trinocular port do?
The third port carries the included CTV 0.5x adapter, which feeds the same image your eyes see to an HDMI monitor or camera. You solder through the eyepieces while a customer or trainee watches the screen — and you can capture photos for documentation.
How is the total magnification calculated?
Multiply the eyepiece power by the objective zoom: 10x eyepieces × 0.65x–5.8x zoom gives 6.5x to 58x continuous magnification. Swap to higher-power eyepieces to extend the range further.
Can I wear glasses at the eyepieces?
Yes. The WF10X23 eyepieces are high-eyepoint wide-angle, designed for eyeglass wearers, and each eyepiece has its own diopter fine adjustment so both eyes converge on a sharp image.
Can it mount on the Pushi repair desk or a YCS arm?
Yes. The 6558S uses the same post-mount standard as the rest of the 6558 ecosystem, so it fits the Pushi repair desk setup and the YCS Dragon multi-axis arm, with the LED ring light and CTV adapter working side by side.
Do you offer wholesale pricing for the YCS 6558S?
Yes. Vexagoo is an authorized distributor of QianLi and YCS repair tools, offering factory-direct wholesale pricing with no strict minimum order quantity. Contact us on WhatsApp or email for bulk quotes and distributor pricing.
