LOGITECH mice and all other products come with a 5 YEAR GUARANTEE...
I have had them for years...very happily....and I sell them as well and we never get any back...
All the best Brett
Good to know, I think I'm gonna go with a G500.
I heard a lot of good things about it + my cousin has a similar mouse but fatter and has been using it for the past 10 years now so i know Logitech makes good/long lasting products.
