The product was just what I was looking for - an inexpensive (this cost $5.00 including shipping), integrated, simple (plug into the USB port without the need for a cable) memory card reader that handles the latest technologies (SD, SDHC, SDXC in standard and micro sizes). I tested the product to read from and write to SD and SDHC cards of various capacities (2gb, 4gb, and 32gb) and it worked well. The product is constructed of rather cheap translucent plastic with caps on both ends (one end is for the USB connector and the other end is for the memory card slots). The plastic cracks / chips easily, and the caps do not fit snugly (are loose and pull off without effort). (The product arrived promptly, but both one end and cap had chipped and rough plastic edges, an indicator of not very good quality control in the plastic manufacturing process).
When I ordered this product, I also ordered, at the same time, an "Integral SD / SDHC / SDXC USB Memory Card Reader Single Slot" for $6.64 (including shipping). The Integral also was inexpensive, integrated, simple, handled the latest technology card readers, worked well on the read / write tests, and arrived promptly. However, the Integral has only a regular size SD slot (it did not have a micro slot, so need to convert the micro size card to a regular size card via an adapter, which generally comes with the purchase of a micro SD card). However, the Integral was very well made of solid plastic and a cap which fits very snugly.
Both cards are relatively inexpensive and work well; the tradeoff is for convenience (Komputerbay accepts micro size cards without an adapter) for higher quality plastic case (Integral).
