QUMOXDual Port CF Adapter Reader for microsdXC TF to Compact Flash CF Type 1 Memory Card

For what it's worth. i inserted a sdhc sandisk 64gb into the adapter and stuck it in my canon 5d mark II. It formatted the card with no problem and i took about 40 pictures. then i uploaded the pictures with no problem to my pc with about the same speed, my sd cards do on my other cameras, about 25 seconds for 40 pictures of 21m bites. i am very satisfied with the results and if it keeps going this way it is a winner.

This did not work in my camera, and now it sits unused in the camera bag. Would not recommend.

While bought this model by mistake, as I wanted the single SD adapter, I figured if test it out. 🤗It worked as it should have. Insert 2 microSD & insert the adapter into the camera, simple right...YUP it worked just fine 😁I tried 2 2gb and even a 2gb & 4gb at the same time, YUP, it read them just fine showing over 1000 pictures could be taken😎. Snapped a few shots pulled out the microSD, pushed in the PC and what do you know ... pictures. I can ONLY assume the adapter will fill 1 side card then the next. 🤷 as I didn't test that far?While yes you can get a ##gb compact flash card for about the same price. Having a standard, newer compatability is way netter!Remember FORMAT the cards AFTER you insert them... using your camera!!.

Probably nothing wrong with the product, but I couldnt get the iPod I was modding to read the new memory, so...

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 use this for a cannon 40D camera. CF cards can be expensive and storage space can run out quick, so being able to use a cheaper higher storage disc is great. The first one I got quite a few years ago is still functioning, but is starting to show it's usage, which I have most definitely got my money's worth.

Was able to use in a card reader, but it would not work in a Nikon D810 DSLR camera, which was the primary purpose for the purchase. Other cards have also been hit/miss with this camera, so I don’t think it’s a bad design necessarily- but also didn’t work as intended.

great
