Any reason to not get the 310? About £50 cheaper and seems to only lack the gimmicky features.
You can really tell the quality difference when you pick each up. It just FEELS so much better. Also has a more advanced sensor if memory serves (it's late).
Rival 310 is great for the price. Rival 710 is just a better mouse all round and that's why you pay the premium. For something your gonna be touching all day go for the 710 over a 310.
Exact same sensor. TrueMove 3 based on the Pixart 3360.
