Items received in good condition. The size of the PCB is totally off. Based on the advert is 7x13mm but the actual size is 17x13mm. Haven't tested since is just too big for my requirement.
Good product for this price, with quality components. Maybe 2A output and 2V input is a little but over/under specified. I checked wit 2.9V input, and 1.2A load. you can see the output of the converter.
