Pros:

• "This one worked right away in the GBA flash carts I wanted to use them for."
• "Works great for my switch lite!"
• "Got this to expand the storage for my 500GB steam deck, and it's been great so far!"
• "The read and write speeds of up to 140MB/s are truly impressive."
• "It transfers files and doesn't lag, everything is done is one swift motion and is done before you know it."
• "They’re resistant to water, shock, and even X-rays."
• "The card's compatibility with a wide range of devices, including smartphones, tablets, cameras, and more, makes it incredibly versatile."

Cons:

• "This one did not fit physically into any of several SD readers."
• "But after using it for a week my phone dropped dead and lost EVERYTHING that was in there."
• "You just can't believe SanDisk hype as for write speed. That lasts for about the first 5 seconds and then slows to a crawl!"
• "The advertised speed of 150 Mbytes/second has a list of exclusions and qualifications listed in font size 3 that take up the entire back side of the package."
• "Tried 2 different sandisk ultras because I thought maybe I got a bad 1 but no turns out these do not work for dash cams."

• "This now makes two 32 GB cards that have failed in the last 60 days."
• "Was unusable quickly for one of them. Can’t format or write to it anymore."
• "Got this in July and used on Fire HD 10. Worked for several weeks but now it’s corrupted and my tablet could no longer read it."
• "One of the pair I received went into thermal meltdown shortly after being fitted - burnt finger tips removing it."

• "Soon after the Amazon's one-month return period, the memory card stopped working."

Value and Pricing

Pros:

• "For the price it can't be beaten, and in the moment, they never let me down."

• "SanDisk doesn't tell you what could be the roadblocks in getting a reasonable speed."
• "You don't have to worry about getting a fake card."
• "This was a piece of plastic painted like a 1TB Sandisk card. It is a counterfeit prop, NOT A MEMORY CARD DO NOT BUY THIS UNDER ANY CIRCUMSTANCES."
• "So these are very expensive write-once cards that we can't return because our data got stuck on them."
• "This 1.5TB version just doesn't cut it."
