No problem with this particular card purchased. A disappointment all the same that explains this relatively low rating of 3/5 stars: Sold and marked as an SDHC Class4, enrollment rates of 2.53 Mbit / s write and read obtained 4.58 on my HTC Desire with Disk Benchmark exactly match performance of a map of Class 2 only. It is unfortunate that Kingston is not reliable as to the exact performance of its media, although in my daily use it does not really penalize me. A simple matter of transparency and quality / price ratio, the information given to buyers benefit from being accurate.
