This is a fantastic product because it will work with download accelerators like speedbit's freeware version. Also, my room is on the opposite side of the house to the wireless router and is in a less than ideal place for connection speed.
Some wireless devices will not work with download accelerators. I'm able to get up to 1mb speed depending on network user volume at the local exchange combined with speedbit, which is tremendous considering another PCI product only achieved 100KB speed. A big difference.
However, after a 6 months of use and in the summer the dongle keeps dropping the connection. This is due to the chip suffering heat damage because of its high performance versus cost. When I run my PC for more than 4 hours and pull the wireless dongle out of the USB socket the metal of usb connection is around 55-60c, which means the chip is probably at 65-70c. It ceases working properly and keeps dropping the connection e.g. needs replacing.
It is a great product (fast), but will not last more than a 6 months if your PC is very distant from your router and you use download accelerator.
