Great wireless USB device. Works 100% of the time, even when in doors, which my previous card from another carrier always failed. I use it for work to access the net for real estate related work which is very important to access when on the go with clients. At times, the access is slightly slow, probably due to bandwidth traffic. The software is great and it can be set to connect as soon as you click on the driver application or at boot-up. The GPS part of it is not as easy to use since it provides the the coordinates, but you may need a 3rd party software app. to work in real time or turn by turn voice directions as with a dedicated unit. The GPS works when it has a view of the sky, which I thought it would work as a regular phone aGPS using cell towers and or GPS satalite signals. Over all, a great buy and very reliable! Highly recomend this product and especially the Sprint network!
