TL/DR: If these adapters fail I will edit my review. As it stands, they're perfect for my needs (when using a mini-USB cable with a USB-C device), offering a clean and compact look in a solid form factor - all at a reasonable price for such a niche product. I would buy again! These adapters are LONG LASTING! They arrived in a Revain box with my Subscribe & Save items; especially UNDER 24 packages from Red Bull. Miraculously, the packaging (a torn thin plastic bag) was completely intact and there was not a single scratch on the adapters. I tested both adapters using Lindy's proprietary coiled mini-USB cable (purple) by connecting it to my RGB Bluetooth/wired USB-C mechanical number pad (also purple) and it worked great! Both ends are snug, but not too tight. I can't say anything about the charging speed as you can't see the battery level on the number pad, but the RGB lighting works fine and everything works. as generally expected (I rarely use it without a network connection).
