Return Policy

Please refer to the product description for each specified return policy of the underlying product. We offer 5 days money-back for Pro Flexer Otg, Otg2, Otg3, Otg4 and E. Please be noted shipping fee is not refundable.

Otherwise above stated, properly functioning products are not returnable. Due to high demand and depreciation, we do not accept return for a faultless product. 

Our products are well manufactured, proven in our lab and pre-tested before shipping. We 100% guarantee a faultless product but we do not guarantee performance, that is, for example, if the Flexer is clicking properly but there are no blocks being released as our product beats the competition, but does not invent blocks to catch.

Exchanges can be made due to a faulty product by nature. We will replace defective product or its parts immediately at our shipping cost within one month from the purchase date. However, if an exchange is requested for a properly functioning product, GNNGB reserves the right to refuse the exchange or to charge a minimum 15% handling fee and shipping cost. Buyer will be responsible for paying for their own shipping costs for the returning item. GNNGB does not accept claims of "not being able to catch blocks" defined as a faulty product, as there are many possible external factors such as numbers of blocks being released, network speed, phone model, etc. That is, we are responsible for the machine performs clicking effectively on the screen but not for picking up blocks. Please contact customer service for an arrangement of exchange. 


Return (for refund) can be only made if the product is faulty and can't be exchanged for out-of-stock or discontinued. Under certain circumstance if we agree you to return properly functioning products, the refund is subject to at least a 10% restocking fee. To be eligible for a return, your item must be faulty and in the same condition that you received it.

If all conditions are not met, for example, the tape is used or plastic of clicking head is unsealed, GNNGB reserves the right to refuse the return or to charge a minimum 20% restocking fee. All returned items must be in new condition, in their original unaltered box and must include all packing material,  manuals, and accessories. GNNGB can only refund the original purchase price.
