Kingston 8GB Class 4 MicroSDHC Card Flash Memory with SD Adapter SDC4/8GB

This card works reliably and I am satisfied with it.

great price

It works for the tablet that I bought it for. But it does not work on my laptop when used with the insert that it comes with or it would have received five stars

Used on Roku Premier, format fast and successful

Arrived quickly in perfect shape and went straight to my Roku boxes to replace failed 2GB MicroSD cards. Hopefully they won't fail too.

I had to buy this because my Biqu B1 3D printer said it was the only thing accepted for updating the firmware. My Mac refused to see this as writable, though. I tried to reformat it, I searched on-line for help, and tried resetting my preferences. No matter what I did, it was read-only, so I couldn’t redo the format or save the firmware onto it. Finally, in desperation, I tried a lot of wiggling and jiggling in the slot, and it magically appeared as writable! So I quickly copied the program onto it before it disappeared again. It worked just fine on my 3D printer, though, and I was able to update the firmware. It would seem that the contacts are slightly off on a Mac, but I’m not an expert.
