Service Announcement

Date: 22/11/2024

Those who have ordered RT31 from our AliExpress store recently and are facing issue with calibration not saving on the device and the hand brake blocks the usage when pushed forward.

Please write to us at [email protected] with your order number from AliExpress, your shipping address and use the email subject : "RT31 Hand brake v1.7.2  Replacement". We will verify the batch details from the order number and re-issue a new control box to those who have received the device from the defective batch. 

We take our product quality very seriously and we apologise for this issue, as it is due to the incomplete firmware .

Thank you for your cooperation.
