Good product,value for money. Naaptol sell this product at very low price than market.and the quality of the pen drive and msd card is very good.

This USB adapter for the micro SD card is very handy to have available. I tend to work on a lot of older lap tops and desk tops, that do not all have card readers, so this make data transfer much easier for me.

Highly recommended this product, very fast transfer 100% satisfaction guaranteed. I love it. And it's got life time warranty as well,

have always used these SD cards in phones and cameras and they work great. fast speeds and less lag time.

I got this to increase the performance on my raspberry pi 3 and compared with the one supplied by CANAKIT it works better

The purchase of the cards was smooth and easy. Take 24 days for the shipment to arrive, though. Granted MobileFun was not responsible for the slow shipment but was caused either by Royal Mail or Canada Post.
