QUMOX DUAL PORT READER ADAPTER For MICRO SD/SDXC TF TO COMPACT FLASH CF TYPE 1 MEMORY CARD

Again another great purchase. This item read and write speeds were decent for the hardware it was purchased for. So all In all great item

Not working at all

Like the title says, only one side is working, difficult to fit but a 32gb card did fit, just. However it does work, in both my Canon EOS 50D and 5D mkII with no issues so far, also tried in a 40D and 450D again working.

Excellent quality and value very versatile

Arrived intact and quickly, Works as expected.

Did not work for Canon 400D

Does not work at all. It couldn’t work no matter I put in one or two cards.

Doesn't work

I just received a microSD to CF adapter and ran some test on it. The card works as advertised and I was very impressed. There are a number of bad reviews but the question is are they for the microSD or the regular SD adapter. You also have to understand something about file systems and computers besides just cameras. The card worked excellent with one microSD card in the first slot, it also worked with two microSD cards but they had to be the exact same type of card you cannot mix memory sizes. If you use two cards it stripes across those cards so you cannot take one out and use it in a computer by itself you have to use them inside the adapter. That is not the same if you only use one card you can then use that inside of a computer without the adapter. I haven’t tested speed yet but as far as total size of cards my canon 7D uses fat32 to format so the total combination of the cards cannot exceed 132 GB and again they should be the same size and type of cards. Mine was made in Taiwan don’t know if that makes a difference if they come from different places but I’m happy so good luck.UPDATE: Returned card. Apparently after you format two cards in micro adapter at once, the cards become unrecognizable in any other device. Had to return cards to adapter one at a time and format in camera and then in PC for them to work again.

I bought this version as well as the SD version. Both work great and will save you more than a few bucks. No brainer.

Even reformatted the card to get it to work and it doesn’t work waist of money

Did exactly what it said it would do. Quick delivery and a good price.

Out of the bis it doesn't work, tried it in three different cameras and sealed different sizes micronSD cards even one at a time all the combinations and the device is showing me CF CARD ERROR 😤😓🤬....NOT WORTHIT EVEN 5cents. Now because I don't have a printer to print the return papers to get a refund I'm gonna trash it and call it my loss their gain 👍 BRAVO
