First of all Flipkart Rocks. Definitely the lowest prices around.

Now about the cards............
The SDHC (Secure Digital High capacity ) cards are the most common form of data storage devices now a days. The version running is 2.0

They are basically classified on two properties
1. The first is obviously the capacity ( 2GB , 4 Gb etc )
2. The second and the more important is the minimum stable data transfer speed (DTS).
As per this category there are classes in which these cards falls
...

FK is getting amazingly better! This product was delivered in exactly 48 hours to Shimla (my earlier orders took a bit longer). Anywez, this product is a class 4 memory card i.e. having a transfer rate of 4 MB per second. The printed MRP is Rs. 699 though in market it costs around Rs. 400, but FK made it best buy for me.

best memory card 👍💯

It worked on my BB9520......... It hanged for the first time, but after rebooting it started to work superbly.....

It belongs Class 2...... Speed is good.
BB has problems supporting ordinary memmory cards....... But this thing worked on my thing very perfectly.

After the startup hitch i hadn't had any other issues...

It also says 5 year limited warranty, but i am not sure of it...

We can use 3.75 of the total memory...
The overall performance is excellent... I recommend it.

its nice to have good and quality products for a reasonable price.......
i'd recommend that anyone out there who wishes to buy this should definitely go for it...... its really a bargain!!

Its a decent product at a reasonable price.
Has good read and write speed. Its Sandisk so don't worry, just buy it.

IT'S GOOD TO HAVE A PRODUCT FROM FLIP KART. BETTER OPTIONS TO GET BEST PRODUCT ....I HOPE EVERY PRODUCT HAS GOOD QUALITY AND BETTER CHANCE TO GET GOOD PRODUCTS

Good product at reasonable price. I strongly recommend this memory card for low end devices. Better speed and performance

First of all..SANDISK is indeed one of the leading brands of memory cards..And when it goes to 4gb though not being the higher ranges of storages,this 4gb is comparably fast and responsive compared to its class "4" as it highlights!
Its indeed a good product but i believe if the product would be available for 30-40 rupees left it would be more convenient and satisfactory!
