FAQ

 

Q: How do you guarantee the quality?

A: Normally, we offer a one-year guarantee from the date on the B/L. If there is a quality problem, we promise to return the goods or refund the payment.

Q: Is OEM available?

A: Yes, all goods can be customized according to your requirements, including packaging, logo printing, etc.

Q: Can we buy 1 pc for sample testing?

A: Yes, we are glad to send 1 piece for quality testing if we have stock of the model you require.

Q: How do you deliver goods for trial or small orders?

A: For small orders, we prefer to use international express services such as DHL, TNT, or EMS, which are faster and more convenient for customers. We also cooperate with an express agent who offers us significant discounts on shipping fees, much lower than official rates. For products with detachable batteries, shipping fees can be reduced if the goods are sent without the battery.
