Proof of purchase a must for warranty repairs?

[Thomas Porfert]

Including a proof of purchase when claiming warranty is highly recommended. Without we have no way of knowing when you actually purchased the product. Sometimes we have ways of telling how old the controller is, and if we can verify it was not made more than a year ago, we will usually consider it within one year; but there is no guarantee without the receipt.

There are of course other factors when it comes to warranty, not just the proof of purchase. Here is a direct quote from the repair page on our website:

WARRANTY IS VOIDED BY

• Using controller outside of its intended performance specification (running outside of MAX voltage/current, gearing, or wrong application/vehicle).
• Physical damage including crash, or water submersion.
• Modification of controller such as soldering on controller, gluing items on the controller, potting the controller, etc. There are no user-serviceable parts on these controllers, we do not recommend attempts to repair or solder on the board.

Note: warranty is for original purchaser of the product only. Warranty is non-transferable.

So unfortunately if you purchased it from a friend, we generally do not accept it as a warranty. We can make exceptions in certain cases, but unfortunately there is no guarantee.
