Good but interferes with WiFi
It works great and for less than £20 - what a bargain. It really works and from quite a distance, it was just plug and play for me.
But I'm with BT and I use the BT Home hub as my router and it also uses 2.4GHz so when you use this it blocks out my WiFi signal. I'll try and find out if i can change WiFi bands. If I can't I'll probably send it back if can be bothered (which i probably won't - it'll be a £17 lesson to do more research about the frequency of my wifi router).
