I just bought a basic Logitech M705 Wireless mouse for my laptop and HOLY MOLY WOW IS IT NICER THAN MY RAZER LACHESIS!!!!!!!!!!!!!!!!!!!!!!!!

VS.

Yes im sad because I payed 30$ for this mouse, when I payed 70 for the lachesis 3 years ago...
Now, what I am wondering, is a "gamer" pad actually worth it to keep the teflon pads under the mouse nice and smooth?
I do realize that I abuse my lachesis much more than my laptop mouse so the longevity of the lachesis is going to be far less than the M705 I just bought...
I knew from a long time ago that my lachesis was running on its last legs, even though it pains me to say it, because the mouse is perfect, nothing wrong with it, just those stupid crappy little teflon pads on the bottom that are completely worn out... Which makes the mouse feel sluggish and slow while moving it on my desk.
Is it worth me investing on a mouse pad that is worth 40 - 60$ or just buy a new mouse every 3 - 4 years?
