Ive heard that hp/Fitbit/Logitech are easy af.
Maybe one of these is possible?

In terms of Fitbit, given their Items are extremely light, you can use the Item missing method.

Fitbit SEing works differently. You "borrow" accounts with fitbits on that haven't been synced in   > 7 days

That's one method.

In terms of "returns", boxing will suffice. Pertaining to receipt of goods, the missing Item works well. Variation Is paramount with every SE, hence you need to Identify and exhaust all avenues- namely methods.
