Q: What should I do if I never receive my product?

A: Amazon takes responsibility for all issues regarding FBA shipment as all FBA (Fulfillment by Amazon) orders are picked, repackaged, and shipped by Amazon. We encourage you to talk to Amazon customer support first to get timely help.

Q: What should I do if I receive a wrong product but not the one I purchase?

A: If it is a LENTION product, feel free to keep it if you like, if so we would process half a refund on your purchase. If the item doesn't meet your need, we will send you the correct product asap. Sometimes Amazon may pick a wrong item from other brand sellers, in this situation, please contact Amazon customer support for the reimbursement directly.

Q: What should I do if my item doesn't work upon arrival or fail after some time?

A: Please check the compatibility first, if your devices are not compatible, we encourage you to refund through Amazon directly. If the product came defective or broke later, we will either issue a free replacement or a full refund to help you out after confirming the issues.

Q: How do I get a replacement during the warranty period?

A: Please fill and submit the "Customer Support Form" above first. If you are in urgent need of a replacement, the fastest way is to place a new order on Amazon and offer us the new order number, we will fully refund your new order once it is complete. Or we will send you the replacement after confirming the issues.
