newbie - amazon re 32gb sandisk extreme card - advice please

Sandisk 32GB 45MB/S SD Extreme Video Memory Card - Frustration Free Packaging

Dear All

I have an 8gb class 10 Sandisk Extreme card HD video and as I am travelling to USA for a few weeks Florida I wanted to get some extra storage particularly for some videos - I have seen the above 32gb from Amazon and I wondered if any of you professionals would take a look and offer your advice please

I have been spooked as there is 1 reviewer on there who said his disk was a fake but bought through amazon on market place but this purchase would be directly with amazon

I have chatted to amazon and they have stated their standard stuff that its brand new and genuine

Still would be grateful if you can offer your thoughts

thanks indeed
