Really needed a new one as last one bumped many times in travel was no longer reliable.
Did much research and this TP-Link usb stick was raved about as a great wifi stick.
Found it on here and was happy that the price here was as anywhere if not cheaper than many online sellers.
Bought it, got it in excellent as usual Mighty Ape delivery times, and happy to be online without fears of getting bumped every few minutes.
It is plug and play, nothing was needed to get it up and running :)
