FWIW The last 2 revisions of firmware could smoke yours.
I purchased a pair for my XR10 in April. Friend help me solder everything up. They must have been running FW .28, He updated to .29 and .30 and poof. They are smoked.
Tekin will replace for free, but takes about a week and half. They have a new FW .31 to fix the issue, but not puclic yet (or the last the last time I checked earlier this month). They will email you the updated hotwire + .31 update upon request.
So beware.
