Item received is not a Silicon Power product and it's not even a class 10 working microSD card! The card received writes at 4m/s and only 2gb can be used. Bad experience buying from this seller, did not even bother to send a counterfeit product and simply just replaced the item with a China made brandless fake card. Thumbs up to your bravery!
Output:
Negative Review
