On my last trip to the continent I discovered Temu. Ordered a wireless doorbell with a camera, but it is not working because they forgot to install two blades/plates in the battery compartment. It is a quick fix but I wonder where I should go in Argentina to get two sq. cm of metal to install in these slots. I believe they should be standard size since batteries are the same size anywhere.
Temu refunded me the item, but I haven't had the heart to throw away the whole thing on such a simple and quick fix (if I find it).
