I have always supported Kingston memory products.
However, I am disappointed to note that there is currently (as of 29th October 2010) no indication as to the speed of this particular device.
There is no mention of data transfer either as MB/s or as an 'x' rating, such as 20x, 133x or 300x.
This makes me wary that the speed is less than 133x and therefore capable of less than ~20MB/s.
It's also confirmed by the other reviewer's remark that it is slow.
For this price, you can get rated CF cards, delivered free if you select Amazon Prime or one of the few companies offering a 'true' Free Delivery option.
Kingston are robust but omitting the speed of the device should ring alarm bells for you.
