NEEWER 16 channels RT-16 Wireless Studio Flash Trigger




All Neewer products carry a 1-year warranty (used products supplied by a third party are not covered), valid from the purchase transaction date. The warranty covers product defects and provides replacement of the defective product or serviceable component.

If a return is required, the buyer is responsible for any associated return shipping costs (i.e from the buyer to Neewer’s return address) and Neewer pays for postage to ship the replacement item back to the buyer. In some cases, at Neewer’s discretion, the buyer may receive a refund if a replacement is not immediately available. Refunds issued are for the cost of the item only; no handling or shipping fees will be refunded. Please note that before a replacement item is dispatched, or refund issued, Neewer must receive the returned item in the agreed condition. As our sales are online, without a physical store to inspect the defective product, we reserve the right to request picture or video evidence illustrating the defect to honor the warranty.

Please Note: Your product is automatically covered under warranty effective from the date of purchase. Please provide your order number and a photo / video in the event of a claim.  For Amazon orders, the name of the seller, or a screenshot should also be provided.

  • Used products from a third party, such as from Amazon EU S.a.r.L., Services LLC, etc.
  • Normal wear and tear.
  • Loss or theft.
  • Physical damage due to misuse or accident.

  • Only Neewer products are covered, no other item is covered, including items used in tandem with a Neewer product, irrespective of cost.

  • Buyer attempts unauthorized repairs, modifications, or disassembles the item.

  • Item is damaged by plugging it into an incompatible voltage. All plug-in items have voltages clearly displayed on the Amazon detail page. For international travel, a step-up / step down convertor is required to accommodate these variations.

To claim a warranty, please reach out to us at All claims for products missing / not received must be registered within 90 days of the purchase date. After this time, we no longer have traceability with our logistical providers and cannot accept a claim. Contents of the package should be checked upon delivery and any missing parts claimed for within 2 days of receipt.

Extension requests to the warranty due to COVID are regretably not commercially viable. We have continued provision of products for purchase and use throughout the pandemic and our team continues to work hard to sustain this.
