Works as intended.
Works well with a card reader. Used this to write new eSIM profiles to an eSIM adapter card.

Slick and robust multi-form factor reader
This adapter pairs perfectly with the Gialer reader. I tested every form-factor offered by this adapter and all worked! It even works with pcsc tools on Linux, plus it has raw APDU support. Perfect for SIM card hacking.

Works, but a little too short for the built-in reader in my Thinkpad
For most external card readers I imagine this works great, however it's a little bit (about 2.5 mm) too short to work in the card reader built into my Thinkpad because the full-size card reader slot interferes with my laptop's case.

Without some form of direction to show you what you're doing it's basically junk.
There's no directions or anything that shows how to operate this thing is basically worthless.

Works great, but full size adapter slot seems redundant, adding bulk and weight.
This adapter is well made, but I don't know how long the contact points will last. For the price though, I can't complain. It works as expected.
