Smart Plugs Quality Control: Frequently Asked Questions (FAQ)
Why do I need product inspections for smart plugs?
If you are worried about or have experienced problems such as poor quality, incorrect shipments, or wrong packaging for goods imported from Asia, product inspection services is your solution. V-Trust product inspection service can help you have accurate understanding about the quality of the goods without going to the factory by yourself.
Do I need to send you an approved sample of the smart plugs?
It would be great if you can send the approved sample to V-Trust before the inspection for reference. Compared with product photos or specification documents, a real product sample allows V-Trust engineers to do a more thorough comparison check.
How many days in advance should I book the inspection?
Though sometimes it's possible to book next-day inspections for many manufacturing clusters where V-Trust has a large team of full-time inspectors, we recommend booking with us at least three days in advance. Early booking is important for appropriate scheduling and good preparation before the inspection.
Who will I be in contact with throughout the whole process?
There will be one dedicated account manager who will be assigned as your main contact point at V-Trust. You will receive prompt responses whenever you have any questions regarding the inspection arrangement.
How long does it take to know the inspection result?
The official report, reviewed and signed by an authorized V-Trust technical manager, will be available within 24 hours after each inspection. Same day report is available if you would like to know about the inspection findings on the same day. V-Trust has the highest same day report rate in the inspection industry. In this way, you can start to communicate at the earliest with the factory for correction if necessary.
What if I have questions after I check my V-Trust report?
Please don’t hesitate to contact us whenever you have any questions. Our team is always available even after the inspection is completed.
