Let’s not bury the lede: I prefer the Sensei Ten over the Rival 310. I wouldn’t transport the Sensei Ten without some kind of case. It’s also a shame it doesn't come with a detachable cable, or at least a braided one, because the included cable’s plastic is easy to crimp. People who play a lot of MMORPGs, MOBAs and other games that benefit from a lot of side buttons might not appreciate the two easily accessible buttons this mouse offers. Still, the Sensei Ten isn’t for everyone. It’s heavy enough that I don’t lose track of it but light enough that flicking across the mouse pad doesn’t feel like a chore. There are lighter mice on the market, and some people would prefer the option to adjust the Sensei Ten’s weight, (like you can with the Logitech G502 Lightspeed), but the Sensei Ten feels like it hits the sweet spot weight-wise. Somehow, the Sensei Ten also feels lighter than the Rival 310 even though it weighs more (92g) than its older counterpart (88.3g) without the cable.
