As an owner of the HTC Touchpro and Samsung Propel, I was frustrated with the limited memory on each device.  This memory card solved the problem, allowing me to easily transfer data between both as well.  Works perfectly, setup was a simple as plugging the card in either device.  The Micro SD adapter is great as well, allowing me to easily transfer photos onto my laptop.  I cannot think of a cheaper way to get extra flash memory than this.
