I always trade-in in person now at the Apple Store. Too much risk involved in sending it out.I sent in an iPad Pro. When they received it, they said the chassis was bent. I never noticed a bend, but it was one of the models mired in Bendgate. I sent that information over to them, and it was reevaluated at the original estimate. If there was a bend, it was not significant enough for me to have noticed. Even then, they should have been aware of the Bendgate models.
