So, the reader is fine for purchase, I retract my bad review, and unequivocally state that the vendor showed immediate concern and was willing to do whatever it took to make right any faulty product. The situation corrected with the passage of time and some apparent Windows updates. I apologize for any extra efforts caused by my original post but initially, the product did not perform as expected on MAC or Windows.
But, after posting the negative review and immediately receiving an email expressing concern from the vendor, I inserted the card reader again just to give them a screen-shot of the original error I had received along with driver info, etc., the thing worked fine.
Granted, a few weeks had passed so I guess Windows needed some updates to drivers or whatever. Turns out ironically that after I posted the bad review below, the card reader started functioning as I'd originally expected. UPDATE: My first bad product review was posted below as this was the first problem I'd ever had with a product I purchased on Amazon. Reviewed in the United States on May 8, 2018
Vendor was Very Involved and Willing to Correct Any Problems But I couldn’t be more happier with this card reader and it also makes it easier to show my clients on my cell phone or my tablet the images that I produced. This is a lot different than a regular JPEG if you do not know this. And now mind you I am downloading raw images files. I am downloading it to my cell phone takes less than two seconds per image and it is the quickest way I have found to download the larger images. So I bought this card reader that comes with a USB three to USB see adapter and I downloaded that android app USB media explorer that downloads the images to Adobe Lightroom cc. Seeing that the image files are so large from the Nikon D 800 that were 90 MB an image my laptop would take 2 minutes for each image to download. I bought this CF card reader to download the image files from my Nikon D 800 to my Samsung galaxy note 8.
