I had issues with a Wahoo Headwind fan. I could use it manually, but Bluetooth was not functional.
They offered a return label and upon receipt would ship as replacement as soon as one became available.
I asked if I might guarantee a cross ship with a credit card, then when the new one finally arrived, I could reuse their packing to return mine.
This would also permit me to continue to use mine manually while waiting.
They approved and two weeks later I had a new one in hand.
credit card refund followed a couple day after they received my return.
customer service was top notch.
I understand some people might not wish to use a credit card for the cross ship. For such an expensive item is not unreasonable to expect you to return the item prior to replacement.
