Buyer Questions

About The Knowledge Center

Are these articles written for buyers or end users?
For wholesale buyers. They cover how to judge a device, how our services work, and what our commercial terms mean in practice.
Can I reuse this content on my own listings?
Ask John Woo first. We can usually supply product copy and images for your listings as part of an OEM order.
Do the guides link to the products they discuss?
Yes. Every guide links to the relevant category and to specific models.
Where do the specifications in these guides come from?
From the manufacturer specification for each model. Where a figure is not published we leave it out rather than estimating.
How do I ask a question that is not covered?
Message John Woo on WhatsApp or email [email protected]. Answers usually arrive the same working day within Monday to Saturday 9:00 to 18:00 GMT+8.
