Sorry it didn't work out for you, but it's always a gamble with a pricematch like this one. If you don't mind paying around $33 shipped, you can get a similar one here -

Another thing I should mention (unrelated to the price of the card) is that cluster size can make a difference in how the card responds. The smaller the cluster size, the less wasted space you have. However, it also slows the responsiveness of the card down overall. A larger cluster size (i.e. 32k) will make your card more responsive, but will also waste more space. For example, a 1k file will take up the full 32k in the latter scenario. If you had 4k clusters, you would only be using 4k for that same file.
If you have a lot of files less than 32k then you might be better off formatting the card with 4k clusters. Otherwise, I would suggest the larger cluster size of 32k to get a better response out of your card.
I have done this in the past with slow SD cards to get a better response. For example, on my hacked GPS unit with all the maps on the SD I used the larger 32k clusters from the default 4k. After doing that and copying my files back over, I had next to no lag. With the 4k clusters, I would regularly get lag as the GPS software was reading the map files.
I have also done this on my media server, but I used 64k clusters there. This was suggested over at the SageTV forums (which is what I run on my media center). This got rid of stuttering I was experiencing on HD movies and tv shows.
To format to a new cluster size, simply right click on the drive in Windows and choose format. Choose quick format, FAT32, pick your cluster size and I would suggest you check the "quick format" unless you have a lot of time to burn. WARNING: A format will wipe all data from the card, so backup anything you need. If you don't have a way of mounting the card on a PC, you might google to see what other options you have for formatting.
If your want to see your current cluster size in WIndows, go to a command prompt and type "Chkdsk X:" (without quotes) where X is your MicroSD drive letter. You will get some outpul that will include something like mine
32,768 bytes in each allocation unit. This means mine is currently at 32k (32,768 bytes).
There's lots of literature you can read online about this and its pretty common. Below is a quote I pulled from one site that explains why larger clusters can increase performance.

What is an issue is how fast your system can read and write files from the hard drive. The larger the cluster size - the larger "chunks" that are fetched from the drive. This speeds up performance. For example, many drives were formatted with 4k clusters. This means to read 32k of data, the system must perform eight fetches - 4k per fetch. If you had instead formatted the same drive using 32k clusters, the system would only have to perform one fetch.
