- I saw how someone bought this mouse for 5k . That's 5K for it is too much. But for 1.5-2k just right. The wheel has not yet broken, as many comments have threatened. Pros: - small) Despite my childish hands, I always used to lean towards large and heavy mice with a large number of programmable buttons, until I decided to try something less bulky. And for my small palm + using the finger grip on mice - this mouse turned out to be very comfortable. - Since it is small, it is light. The load on my brush has decreased and it is felt. But for those who are looking for very lightweight mice, it is probably better to look towards other manufacturers. - It may be shortened, but it's still Razer's Viper. Symmetrical mouse, for left-handed and right-handed users with a comfortable smooth design. - A soft wire that does not bend into unthinkable pretzel threatening to break the wiring. - The optical sensor is not buggy, it is well read from the rug and wood. Haven't tested it on glass or uneven surfaces. - Supports Razer proprietary backlight settings. Not very useful, but nice. - Surprisingly durable. The dogs overturned a mug of kvass on the table and the mouse fell under the distribution. Only the sensitivity switch key is a little stuck. Has some cons: - Let it be symmetrical, but additional keys are only on the left side. All the same, right-handers are more loved in Razer.
