We offer lifetime battery warranty for our DELTA Kickstarter Backers. Due to cost considerations, customers need to cover the freight fees if the batteries need to be changed.

While DELTA is guaranteed for life for Kickststarter Backers, we do not offer refunds, returns, or exchanges on items received as Kickstarter rewards (except for product quality problems).

The support we get from our Kickstarter Backers is what enables us to run and grow our business, gather customer feedback, design new products and improve existing ones. In the Kickstarter community, the items that you receive after making a pledge are referred to as "rewards" because they are not purchased in the traditional sense. Think of rewards as gifts that are sent to our supporters as a token of appreciation for their support of our business.

Kisckstarter supporters' unreasonable returns, return shipping costs, and any restocking costs that may apply and Kickstarter service fees (8% of the order ) will be deducted from the refund. 

For customers who purchased on, please refer to the Return & Refund Policy

We appreciate your understanding of our policy and the support from you. If your reward truly offers no value to you, here are a few things that you could do in the spirit of crowdfunding:

1. Give your reward to a friend. Our products might not work for you, but there are many folks out there who might find them very valuable. We’d love for you to share our gear with a friend of yours.

2. Sell your reward to somebody. Many Kickstarter rewards were purchased below the retail value – if you want to recuperate that value and possibly even more, throw your reward up on eBay.

3. Give your reward another chance. Some of our products can take some getting used to. All of our gear is designed for use in a variety of scenarios. Maybe it doesn’t work for you right now, but perhaps you’ll find the right time and place in the future.

Thank you again for your support and understanding, and please don’t hesitate to contact us at if you have any questions.
