Let's start with the packaging ... good on Samsung for producing minimal packaging, in a blister pack that didn't require a Stanley Knife or the strength of Hercules to get into.
Once in, there is a tiny green silicon case and an SD adaptor. I'm not sure that I will ever use the silicon case, but I guess that it would be useful for people who have multiple cards and want to store them securely.
I have a number of devices that use full size SD and I know a lot of new phones use this card. My main use will be in a Nokia N800 tablet which has 2 SD slots and is SDHC compliant and the card works fine ... (actual memory according to the Nokia is 7.6Gb ... a very useful addition of fast storage). I have to date installed music and video tracks and access speed and play-back is fine ... I'm not a techie, so all I can go on is image quality on playback ... v good indeed.
There is a product information leaflet included which states (for the technically minded) that the transfer speed is 17MB/s read and 12 - 13MB/s for write ... and seems to be pretty robust against water, crush and magnets ... the tagline is Memory for Life, so these factors are important ... I do remember when I bought my latest phone the chap in the shop said that many M2 cards snap if you are not careful when inserting ... This wasn't something I was going to test, but with a little respect, I think this Samsung card should stand the test of time.
I did have a problem trying to use the SD slots on my laptop and PC. On the laptop, when I tried to access the SD drive I was told to insert a compatible drive ... on the PC, Windows Explorer crashed.
Despite the fact that the card did not work on these PC and laptop drives, I have an SD/USB adaptor and that worked OK.
So, as long as you have a compatible device or a USB adaptor this is a well priced, robust little card.
