Not as good as a 3S, but less expensive. Hopefully better quality switches than the 3S.
Size: Standard
I like this mouse, but it could be better. I purchased it to replace a Logitech MX-Master 3S, which is a great mouse except the microswitch for the left button stopped being reliable after less than three years. While that's a reasonable life for some users, perhaps, it seemed inadequate to me. My use case is general pc use for searching the web, writing emails, and managing finances. The Logitech wasn't used every day.
The 3S has a higher palm hump, which the Basilisk lacks and I really prefer. The Basilisk is similar in overall size to the 3S, so for the most part it fits my hand sufficiently well. Hump size is the main downside to the Basilisk. That, plus the battery is not rechargeable. What, in 2026?! But I've adapted to it, and battery life so far has been very good. It has the combo BT + 2.4 gHz connectivity with a dongle. Both choices work very well and reliably. I like the center wheel size and action a lot. I like the slip pads on the bottom of the mouse. It has a very handy and perfectly responsive third thumb button that I don't currently use but gamers may find it useful. Only time will tell if Razer's microswitch quality is more durable, reliable, and longer lived than the crap switches Logitech put into the otherwise very good 3S. I have used the Basilisk about two months at the time of this review.
