I am surprised at how much neater and cleaner the TarDisk's AdapterChip is.

The red substance used on Nifty's circuit board (red circle) is an epoxy used instead of a clean solder. The connection points (in the red rectangle) look poorly soldered and dismal looking compared to the TarDisk's and appears unstable against the TarDisk's cleaner chip construction.

This red Epoxy can only add to the reported unreliability and instability of the Nifty MiniDrive.

TarDisk claims a superior build that is better than other MiniDrives, Boasting ease of removal (no tools needed) a more reliable MicroSD to SD adapter chip. At nearly half Nifty's price.
