Well, we alredy know wat that is ... its a microSDHC card.. but what most us don't see it the class... The 'HC' extension doesn't necessarily mean anything but 'high capacity'..

The class is, however, important.. It defines the speed.. its an easy estimation that class 2 will give minimum 2MBps write, class 4 will give 4MBps write n so on.. read speeds are usually way more than that... now.. If you just buy a class 10 card and use it with an average phone ( say Samsung Galaxy Y) ,you wont g...

I bought this a month ago for my SonyEricsson J108i and is working great. So I gave a new order for the same for my Samsung Galaxy Ace.
Speed of this card is class 4 and my mobile handle it better.
You only need to buy class 6 / class 10 microSD cards if your phone is priced above 20K, and supports data transfer at high speed.
Or if you are planning to use the microSD card with your computer like a mass storage device you can go for class 6 or 10.

About the Micro SD Card's:
Micro SD Card are 3 Types...
1.SD (Secure Digital)
2.SDHC (Secure Digital High Capacity)
3.SDXC (Secure Digital eXtended Capacity)

I was impressed with the price of this memory card and Trancend Memory cards are really great because I already have 4GB and 2GB from Transcend so I ordered one for myself. After using it and seeing its speed, I ordered another. Its really cool. I recommend others strongly.

Got it at a very competitive price, offer at flipkart , good for expanding your smart phone storage. It is a class 4 card but OK for medium users. Overall a standard product, if you are tight on budget, otherwise one can go for the Class 10 /16 GB variant by paying a little more.

i liked this product i am using this product for over 3 yrs good one . having better writing and reading speed

Good for smaller phones/ smart phones with not so heavy usage. good transfer speed. value for money. i am using it in my nokia 202

The card's file transfer speed could have been better. But, it works perfectly fine with all phones running on android, windows, bada OS and even symbian S40 Series one ! Good one !

You might get better performance of this card on devices with higher configurations.I ordered this product and it was delivered on time. Kindly note that the micro SD card comes only with the adapter and not the card reader as mentioned in the listing. I have raised a refund procedure. Those who are buying it expecting a card reader please be aware.

its a good product to have its works nicely on supported devices and i would like to recommend my friends for this memory card
