The 16gb micro sd card can fit in many devices such as many mobiles, consoles, mp 3 players and mcuh more. It is a great product and only recommend it to anybody eho either likes a lot of music, a lot of games or likes to store alot of things on there androids and stuff like apps! This memory card would go to waste if it were to be used by someone who only likes music and only gets 200 songs on there mobile the 4gb memory card is enough, no need to waste your money. For those who like music, game and apps - this product is for you. I like all sorts on my phone from the weather, email, games, music and much more and this memory card was great for me infact perfect for wahtever i wanted i didnt need no more or no less! Great product! Oh and with kingston you can never go wrong unless buying from outside the uk!
