There are indeed differences in quality between the devices.
Overall, I now had 7 St.
Of this I have only 2. One of these is now the Sony MRW63 ...
The other device is already several years old and therefore could not read SDHC cards.
Anyway, I was then looking for a reader for SDHC cards, especially cards with a size over 16GB.
Since I own a camcorder that especially requires particularly fast SDHC cards, this was of course a criterion.
Although compatibility with SDHC cards stand in almost every description, not all devices that I bought also able in truth. I had equipment from 5 different manufacturers. Initially, No Name, and then also brand manufacturers.
4 devices have my SDHC 32GB and 16GB SDHC, both class 6, did not recognize. When a mine is by 3 times the mini-USB connector plug in the clinker broken.
In the end I went for the Sony MRW6 landed ... and still very happy with it.
Definitely recommended this device.
It is strongly built, and the data transmission works flawlessly.
