Additional adaptor may be required and returns are costly
Product required an additional $25 adapter that would make the visor look too low. Returning the visor is not easy and not customer-friendly. The customer must pay the return shipping and a restocking fee of $35 if there are any scratches on the product and must use the original packaging. You are definitely not Amazon, and if only two units need adapters, then you shouldn’t have problem providing the adapter for free upon request, or giving a full refund for those few unfortunate people who own non-conforming microwaves.
