Velcro is rubbish and falls off after a short period of time.
But everything else is good.
so what did you do to keep it on ?
Sorry.
I used the old plastic sleeves with velcro off of an older Wagtail I had as the velcro on the new one didn't last very long.
I did mean to try gluing it back on with superglue or epoxy resin but I haven't got round to it.
I reckon it should do the job though.
