No end of trouble with RoboteQ hardware, and lack of support

We've purchased several different brush controller, brushless controller, and BMS products. We've had a very high failure rate, plus little-to-no support. At this point, confidence in RoboteQ is at an all-time low.

Having not received any support to our enquiry about the %CLRST command not being accepted, we decided to try a firmware update to achieve this. However, the XDC2460S (single-channel) page appears to only offer dual channel firmware.

If anyone at RoboteQ can be bothered providing even basic customer support, please provide a link to the correct firmware file.

Thank you,
Roger,
