User Reviews about BlueProton USB 2.0 Mini 4-in-1 Single Slot Memory Card Reader Writer for SD SDHC MiniSD MMC rsMMC

I've had this thing for a couple of years now and it's never given me a problem. Good product; I'd say good price but I got mine for free so that was even better. -- Works great

I have owned other SD card readers, but this one has worked the best and easiest for me. -- Great little gadget

This is a very cheaply constructed card reader. However, I have had no problems using it.
It has worked well. Be careful about how/where you store it. It feels as though the slightest hit would smash it into oblivion. -- Cheaply made, but does the job.

I received this free with the purchase of a 4 GB SanDisk SDHC. Although I have used it only a short period of time, it functions as specified. It is, however, quite large when compared to the typical thumb-drive. But, given its ability to reuse SDHC memory, it's a fair compromise. Note that it does have a red LED indicating power use. -- Large
