I bought 3 Strontium Memory Cards of 8GB (Class 4) each in the month of December. Within two months two cards stopped working & was not detected by the mobile & the computer. The performance was also so slow that at times I had to wait till the data was saved , as it used to hang my mobile.

In the month of February I had given the cards for replacement to there service center. 1 month has passed by & still I have not received the replacement. Every time I visit , they are not of any use. They just say that they have no yet received from the company & even they are out of stock.

Please do not buy such third class band cards. Go for Transcend or Sandisk.
