Review on LANMU Micro SD to SD Card Extension Cable Adapter: Flexible Extender for Ender 3 Pro/Ender 3/Ender 5/Monoprice Mini 3D Printer/Anet A8 3D Printer/Raspberry Pi/GPS/TV (23.6in/60cm) by Dewitt Bhattacharya

My printer worked fine, but I didn't want to reach for it to insert a micro SD card. I thought it would be nice to be able to insert the card into the front of the printer. I also thought it would be nice to use a full size SD card. This extension cord seemed fine for the purpose. Plugged it in, it worked and allowed me to do a print. Now it won't read full size SD card. Disconnect the extension cable and try using the printer's micro SD card slot. My printer no longer reads micro SD cards. I know it's not cards because my computer still reads them. This extension cord destroyed my control board and cost over $100 to fix.
