Review on SanDisk CompactFlash SDCFXSB 032G G46 Everything Microfiber by Corey Owens

So I've been using the CF card in my camera for a few weeks now and everything well, today i wanted to transfer some photos to my macbook pro 2015 and then the problems started. The CF card works perfectly, but the included card reader is junk. I'm not sure if it's a controller speed issue since the card reader uses USB 1.1, but when I plug the card reader into my laptop and try to copy folders, the card reader ejects without warning every time I'm trying to copy a folder or drag and drop some files from the card, it just won't eject properly and nothing I've done would stop it no matter what pot I put it in . The only solution for me was to copy less than 5 images at a time (which took forever) and even then it kept fetching and corrupting my image files every few attempts. This universal card reader is rubbish and not worth what you pay for it. CF card works great, never had any problems with Samsung, I'd love to return just the card reader but can't as it's a boxed item, but I'm hoping the seller will replace it with a higher quality reader with more high throughput.
