I just received this card by Friday morning the commander Wednesday afternoon. Very pleased with the speed of delivery from Amazon. Always so reactive, which is why I command by Amazon. As for the product, I am very satisfied. I use a Lumix TZ5 and no (or almost no) waiting time after taking a photo to view it. No problem in video mode. (This was not the case with another class 4 card too slow). Very happy with the product. I recommend this SDHC card!
