Quality card

Great card for my cell phone. I own Kingston CF, SD and XD cards and none have ever let me down. I will continue to purchase Kingston cards and thank you Adorama for always providing the best prices [...].

It works with Arduino. It's slow on PC


from MN  -  Casual User

For the price I paid for 10 of them, I am fairly happy. Each came with an adapter, which is nice. I think one or two of the adapters became unreliable. This may be the cause of someone's grief. I have 10 so I swap adapters when I find the card is unreadable and narrowed down to two bad adapters. I've used these on my arduino and raspberry pi projects and for file storage. On arduino, if you use a very large capacity card, you waste a lot of time if you tally remaining free space so 4GB is perfect. I will be upgrading to larger sizes sometime soon but the class 10 16GB review is pretty awful. Maybe a different brand or it's the adapter issue again.

Memory card for GPS


from Los Angeles  -  Hobbyist/Enthusiast

Was using to load a Garmin GPS topo map, did fine gut took 8 hours to load the map data on the memory card. Should have taken 3 1/2 hours. Da

Fine product, fine service


from Omaha, NE  -  Semi Pro

Pretty simple here... bought two 4Gb SD Cards at a reasonable price, Adorama shipped them quickly and for free, they work as expected. Never had a problem with Adorama... good experience.


Very good


from Sunny Isles Beach, FL.  -  Professional

It's a simple product that works well. I use it often and I never have a problem.




from New York, NY  -  Professional

I use these cards to put music and pictures on them, so for these purposes, it works great for a low price. Because of the price, you don't get a mini case with each card, and I'm ok with that. It is a class 4 card, which means that you get about 4MB/s transfers, which is decent, but not super fast like a class 10. So for storage, it is sufficient.


Great for the price
