The MicroSD card is pretty good and the access speeds are good even though not as mentioned. Overall, it is a very good buy with respect to the price.
Normally for a class 10, write speeds vary from 10 to 15 MBPS.
Here, it is average 20 MBPS and even more for single large file so better then other class 10 cards.

SPEED DO NOT MATCH WITH SPECIFICATIONS WRITTEN IN PRODUCT DETAILS. Additional sticker displaying 95 MB/s speed has been pasted on original packing. Probably you may see pasted sticker in the product image shown on website also. Flipkart is saying 95 MB/s speed, that is not true, I have used this, its maximum reading speed is 35 MB/s and writing speed is 8 MB/s. Hp company on its original packing has written reading speed of 40 MB/s, so don,t become fool about false claim of speed.

Over all ...

the micro sd is awesome but the reader came with this is not working over all the product is good and by the way the delivery is awesome i got the product in one and half day awesome

It has good read and write speed, better than other class 10 cards.
Copying from PC is really fast. Good to have it

Pros:
1) Fantastic Delivery as usual from Flipkart
2) The product is having good performance

Cons:
1) Packaging could have been better
2) The Performance speed was no where near the promised speed, though it is faster than Class 4 cards.

I will still recommend this for the price factor, particularly from HP

The product is very good and reasonably priced and delivered well within a reasonable time.The packing was also well done and the product was as advertised online.

I m using it more then 6 month. working properly and data transfer is fast n sustainable. A good buy from flipkart.

It's HP, it's Class 10, it's speedy , Works Awesome, and no problem in Reading or Writing Data ! It's snappy , and you get a free adapter ð???ð???ð???

excellent product good and in time service well packed good behaviour of delivery boys. let me not express more than this. it is impossible to give a review containing 100 characters for such a small product

A real surprise from HP .. they are stepping on the their competitors.. Really awesome product.. Used it with Micromax Canvas Nitro A310, Lenovo A7000 and Huwaei Honor 6, plays video without any buffering .. Apps also works really nice ..

Read ----> 35 MBps
Write ----> 15 - 20 MBps
( checked speed in Fedora and Windows 7, by transferring files, videos, mp3...)

I hope it helps you guys.. thanks :D
