Yoswit Smart Solutions - Is there a replacement way for products not purchased from the web store?

Yes.  There are two(2) options to do so:

1. If the product is still under warranty and you still have the original receipt, you may be able to return your product to the place where it was purchased.  The store may be able to swap the faulty product for you if they have a compatible product in stock.  This is given after you have spoken to our Technical Support Team to confirm the product is faulty.
2. If you can provide a copy of your mailing receipt that confirms you have sent your faulty product to us for replacement, our customer care team can have your replacement product released from our warehouse and expedite the process for you.  Please mail your receipt to support@yoswit.com with a scanned copy of the receipt, referencing your name and case number.
