I have used Lexar memory cards for 20 years. They always were very reliable. Lately the prices have been coming down and they are now sold at a very cheap price. I now buy new cards every time they get full instead of reusing them. I just archive the cards after I download them to my computer or portable hard drives. They make great back-ups just in case of an emergency and the computer or garden drive crashes. Perfect quality. Works very well. Good bargain.

NOTE : Advertised write speed in the bullets under the Product header on this listing as of June 20, 2017 says write speeds up to 20 MB/s is incorrect for the 64GB card model number LSD64GCB1NL6332, 2 pack.I received mine wondering about this; so the first thing I did was test them using CrystalDiskMark. I tested at 50MB, 100MB, and 500MB file transfer sizes. READ times were consistently 90MB/s and WRITE times an astounding 44MB/s every time.I use these cards for 4K, 30fps video in my Panasonic G7 and for shooting huge RAW+JPEG files (still photos) in my awesome Pentax K1 and K3ii. These cards are PLENTY fast enough.I am APPALLED... totally DISGUSTED that SD card manufacturers, including Samsung, Sandisk, and Lexar, who claim to be so professional or extreme in their titles of their products REFUSE to morally and ethically obligate themselves to the customer to inform us the CRITICAL data we need to know: SD Card Write Times. These ethically challenged companies hide the write times on their own websites' product specifications sheets and certainly nearly never tell us on retail websites.IN SHORT, though, these cards perform BETTER write times than advertised on this listing. SHOCKING !!!BE SURE you choose the same cards I listed in this review. Smaller or Larger Capacity cards WILL have varying write and read times.Hope this helps all of you. Perhaps we (customers) need to get together and file suit with the U.S. government to force Companies to properly advertise / label performance data as important as it is since we live in a technological society.THANK YOU, AND PEACE to you.Jon

I bought two of the 64gb cards. I am a photographer and I have used these two cards for the last three years. Seeing all of the negative reviews is crazy to me. I don't know if the seller is sending out two different products or what, but I have had no issues with my cards. They work perfectly. I have never had any errors pop up either on my camera or the computer. My camera has never had any trouble with the write speed. Even when taking several pictures at a time or when in burst mode, the write speed is very fast and keeps up with no lag. They hold an impressive amount of pictures, even when shooting in RAW. Also, just like when buying in store or anywhere else they came with the paper to access their recover software, not that I have ever needed to use it. There is absolutely nothing fake about the cards I have and I use them in my Nikon D5200. I only format in camera and I am constantly backing up so as not to rely on the card for my pictures, which should be standard practice for most people as cards can fail all the time.

Seem to work good in my trail cameras

I take a lot of photos and needed a larger card. This one works amazing with my canon camera. Tons of space i have never ran out.

Arrived on time, great value, and works perfectly with my Nikon D780/750.
