    Has anyone tried this with an Apple iPhone?
    A shopper on Aug 8, 2017
    BEST ANSWER: I have a micoUSB to lightening adapter and can say it does not work on an iPhone. Too bad - that would have been super useful.
    128 GB Compatable for micro SD?
    A shopper on Jan 26, 2018
    BEST ANSWER: The device seems a bit slow in a computer but does what it’s supposed to in the android phone. Handy and worth having.

    Good speed
    worked on my Cyanogenmod Galaxy s3. I had some issues with Ext4, but fat32 worked no problem. Transfer rate using my PC was very good, 10MB+/s write speed on a C6 SD card.

    PROS: Small, sturdy, compatible

    CONS: Wish it had two caps

    This thing is SO COOL
    I love this little guy. just plug an SD card into the USB part and it becomes an amazing SD card reader.. not enough? Plug it into your android and VOALA!! It is now readable and you can transfer files back and forth (I use ES file explorer). Not enough? THey even engineered a way to never loose your OTG cap. If you have a mini-lanyard you can thread it through the cap and then through the hole provided in the main part where there is a little loop on the main part. You then can disconnect the cap without it totally disconnecting.
    I feel like I could be a spy with this thing.

    Read, Loud and Clear
    I wasn't sure if this would be useful when I bought it but it works well with the 3 microSD cards I tried it with and I like that it works with both the standard USB and microUSB interfaces.

    Now I can show my dive mates the dive video on my phone soon after surfacing rather than having to collect email addresses and hoping I don't lose them.

    PROS: small, compact, standard USB and microUSB in one device

    CONS: needs to protective caps

    Great product
    Great concept. Have several of these and like the small form factor and ability to transfer files to and from my cell phones and tablets.

    PROS: small size and convenience dual USB plugs

    CONS: cover will wear with time so don't handle like your car keys

    A Godsend
    This little gadget is a very useful device for moving files quickly from any device that it connects to. I use it on my Galaxy Nite 4 & also my Galaxy Tab S. You can also pop this into a computer to move files. I now have a 128 GB micro SD in it. This is a great find!

    Great quality, great price.
    The MicroSD card inserts into the same side as the regular USB port, in a special slot. This means you have to remove it from the slot to get the card in and out, but it’s a neat design. The construction of this reader is really nice and solid. Not flimsy or cheap-feeling. If you get a USB-C to MicroUSB adapter, you can plug it directly into a newer laptop that doesn’t have conventional USB ports.

    Brilliant little device. I have an extra 8GB microSD card so this is a quick keychain reader/backup that I'll use for excess music that I don't want to have on my phone and as a SD card at work with a card reader. Still not sure exactly what to do with it, but it's small, simple, & works great with a Galaxy SIII

    PROS: Cheap, simple, works with Galaxy SIII

    Nice and convenient multi function adapter
    Convenient easy to use adapter for the transfer of files to and from tablets. Does the work of a card adapter and USB adapter all in one device.

    PROS: Very small adapter that works fine. Adds a convenient solution to tablets that only have a micro USB connector for the transfer of micros SD card files

    CONS: None

    Great little device!

    PROS: size + added micro USB

    -great way to store/read from a microSD card

    CONS: protective cap will eventually loosen

    It works well.
    The product is great and functions as expected. The only complaint is that when using the standard USB end, the entire adapter has to be removed in order to remove the Micro SD.
