LANMU Micro SD to SD Card Extension Cable Adapter Flexible Extender Compatible with Ender 3 Pro/Ender 3/Ender 3 V2/Ender 5 Plus/5 Pro/CR-10S Pro/Anet A8 /Raspberry Pi (18.9in/48cm)

Perfect for when you have an SD card mounted deep inside a case. Perfect for retro projects. I didn't have any connection issues with this product either.

I use it to run Raspberry Pi while making copies of sd card and then testing them in the extender.

Update:. I am raising this to 4 stars for customer service. Although it was believed I may have been sent a faulty reader, I had already purchased a replacement from a different company. Vendor reached out and offered to make things right and settled on a refund as I had already purchased anither and didn't have a need for a second reader. The fact that they did this warrants me to provide a better feedback, since I am not sure if it was due to a faulty device or a shoddy product. However they did stand by their product and at least rectified it, but it's still a purchase at your own risk. I got this for my 3D Printer, specifically the Ender 3 Pro and this reader doesn't work half the time. It would switch from Media Inserted to Media Init Failed, which will cause my prints to stop halfway, causing the print to be useless since I can't continue to print where it failed. This caused me a lot of wasted filament, so do yourself a favor and get something else.

I really like the way it allows me to use an SD card instead of a microSD card because the microSD card sometimes gets stuck inside the slot. The only thing I do not like is that the end that holds the female SD card accepter can easily fall and pull the small end out of the microSD slot. I think adding velcro tape to hold it onto the printer or table would be a good idea.

My cable does not work properly. First off, the micro SD part the plugs into the printer does not stay in the printer, the slightest movement and the cable comes out. Secondly, I had to plug the micro SD part into the printer several times before it even registered the SD card then once bumped it lost connection. Lastly, once I did get it connected and everything was "working" (with me holding it in place) if I unplugged the SD card the info from the SD card still showed up on the printer (i.e. no SD card in the adapter but the info from the SD card was still on the Printer, plugging a different card in did not fix the problem). If this was simply one issue I would simply say I gat a bad cable, but with 3 separate issues I have to wonder what's going on with the quality control.

UPDATE: Amazon shipped a replacement which arrived very quickly. While the replacement is better, it still doesn't latch in my original location, the micro SD slot on an Ender 3 Neo 3D printer. Which is odd since this is the one recommended by everyone who has Creality Ender printers. This one does latch most times in other places, which the first didn't, so I will assume the Ender 3 Neo is one of the problems. It still slips out on occasion, so I'm not changing the review to more than 3 stars and I may hot glue it in place where I do use it. Bought this to use in a micro SD slot that is hard to reach and extend the access as well as allow a regular SD card. It wouldn't latch firmly into the micro SD slot. Tested it in five other slots and it won't latch into any, simply ejects after insertion. Returning it.

I didn't realize that I was buying a micro sd to a full size sd card adapter . I thought it was micro to micro. My bad - no biggie - I just used an adapter card for the micro. I am using this so I can access the firmware in my 3d printer without having to take it apart to get to the micro sd card slot. This moves the card out from under the printer to wherever I want to place it. It works great!

This worked perfect for my Pi 5, to run the SD card reader to the outside of the case I have it installed in. Very happy overall.
