[3 Pack] Card Reader for Android,Micro SD Card to USB Adapter, TF Card Reader with Mini Size for Camera Memory Card Reader, Wansurs Card Reader for PC Laptop (Black)

They work fine - I like being able to re-purpose my spare micro SD cards as USB flash drives with these at an economical price.

Shipped fast. Quality product. Slip the microSD card into the adapter and plug into USB port,tada: thumb drive! Put the cap on and it attaches to your keychain or lanyard or whatever.

These are easy to use and work well. Downside is the split ring holder which is press fit into the plastic and comes out without too much effort and won’t stay in afterwards. Would not trust them on my keychain.

Just what I needed for my car's radio! It's so mall that it's hard to mistakenly bump/break it while reaching for something. I only needed one, but I have 2 more to use for other projects! Happy camper!

I ordered these for a Raspberry Pi project. Two of the three worked well enough, but the third was a failure right out of the box. Tried it on a Linux box and a Windows PC, and neither would even detect it. I didn't expect much for the price, but I did expect all three to actually function. That's a shame, because I like the design overall. Having the card reader internal to the USB port makes for a streamlined look, and the lanyard ring is a nice touch. It's a bit tricky to get the Micro SD card out of the slot, but that's to be expected. I won't be buying these again -- 33% failure rate is simply unacceptable, even at this price point -- but I do like the concept.

clever design. Using with 32Gb microSD and they work fine.

Works great with Micro SD Cards

Extremely disappointed. The third time I used it when I removed it from my unit part of it broke off and stuck inside my unit.The black piece in the photo was stuck inside my unit I had to use tweezers to remove it. Thankfully the unit was not damaged. The green board inside is loose and the files on the micro sd card that was in it when it broke are now saying corrupted and I can no longer access the files.

great product, fast delivery

Very solid, easy to use with a light indication. Just perfect.

Bought 3 pack, tried all 3 with a number of different micro sd cards (all brands, all sizes from 32gb to 512gb). The computer sees the device as a reader, but can't see the installed card. Shows "no media". Don't waste your time with this.

De 3 que compré solo dos funcionan
