Delivery OK but poorly designed for SIM reader part that interested me. Having lost in the micro-sim obliged to dismantle (easy) to understand. The card is only maintained on the sides so micro-sim may detach. Without dismantling not easy to understand how well the insert. View photos. Otherwise once understood how the software is sufficient and comfortable. Personally I now use the removed drive, I am a technician and I am careful when handling but we must recognize that it is not practical for the standard user.
