The Razer Basilisk Ultimate is a great gaming mouse. This wireless mouse looks very similar to the regular Razer Basilisk, but with a slightly sharper design on the front and a nicer texture on the thumb rest. It has an ergonomic right-handed design, with a plethora of customizable buttons and 14 RGB zones. Its sensor performance is remarkable and is one of the best we've tested so far and it should be comfortable in any grip type for most people, unless you have very small hands. It can be used either wired or wireless, and is overall a very versatile mouse.
The Razer Basilisk Ultimate is a versatile and well-rounded mouse that's suitable for most uses. Its ergonomic right-handed design and thumb rest make it comfortable for extended periods, and it has quite a few extra buttons, all of which are programmable. It's great for gaming thanks to its outstanding sensor performance and customizable CPI, polling rate, and scroll wheel. It's a reasonably-sized mouse that should be comfortable in any grip type for anyone except people with very small hands, though even small hands will likely be fine when using palm or claw grip. It's also small enough that you should be able to toss it into a bag and use it in tighter situations like an airplane without too many issues.
The Razer Basilisk Ultimate is a very good mouse for using at the office. While it has a more gamer-centric look, it has a comfortable and ergonomic right-handed design, with a thumb rest on the left-hand side, making it comfortable to use. It has several extra buttons, all of which are programmable, which can help you quickly navigate through your applications or documents. The mouse wheel can even be customized via a slider on the bottom of the mouse, to let you choose a more fluid or clicky scrolling experience, which is great. While people with very small hands may have a hard time reaching the side sniper button in claw or fingertip grip, this button can easily be removed and replaced with a space filler.
The Razer Basilisk Ultimate is a decent mouse for travel. While it's larger than mice designed for this use, it's still small enough that you should be able to toss it into a bag or larger laptop case with no problem. It can also be used wired or wireless, which can be helpful when trying to use the mouse in a tighter space like on a plane. It's also small enough that it can be comfortably used in palm grip by any hand size, and only those with very small hands will have a hard time with claw or fingertip grip.
The Razer Basilisk Ultimate is a great mouse for FPS games. It has one of the best sensor performances that we've tested, with a wide customizable CPI range, adjustable polling rate, and the ability to reprogram every button. There are 14 customizable RGB zones throughout the mouse, and the feet are a nice upgrade over the regular Razer Basilisk, allowing the mouse to glide easier on your desk. It can be used with any grip by any hand size, and people with smaller hands will likely only have issues with fingertip or claw grips.
The Razer Basilisk Ultimate is an excellent mouse for MMO games. While it doesn't have as many buttons as dedicated MMO mice, it has three additional buttons which, along with every other button, can be reprogrammed within Razer's software. Unlike many Razer mice, the scroll wheel has a L/R tilt which can also be reprogrammed. It's comfortable enough for marathon gaming sessions and can be used in any grip type by almost every hand size, though those with very small hands may have a hard time reaching the sniper button with claw or fingertip grip.

The Razer Basilisk Ultimate looks very similar to the regular Razer Basilisk, but with slightly sharper fronts on the L/R buttons. The thumb rest on the left-hand side also has a different texture to it and feels a bit more premium. It has the same RGB lighting strips on each side, on the mouse, and on the logo as the regular Basilisk. This mouse looks rather similar to the Logitech G502 LIGHTSPEED Wireless.
This mouse has no weight optimization.
The Razer Basilisk Ultimate is decently portable, especially for a gaming mouse. While most people will likely use it strictly with their gaming setup at home, it should fit in larger laptop carrying cases or bags and you can store its USB receiver in the mouse.
The build quality of the Razer Basilisk Ultimate is excellent. While it's made of the same dense, good quality plastic as the regular Basilisk, the feet feel even better. There are no loose or wobbling parts.
The ergonomics are great for right-handed people. Its shape is quite comfortable with easy-to-press buttons, and a thumb-rest on the left side.
Update 09/15/2020: Added a clarification about the overlap of the right button towards the side of the mouse.
This mouse should be comfortable in the palm grip for people with any hand size. However, if you have a medium to extra-large-sized hand and you rest your ring finger near the right button, you may accident click it because the right button overlaps towards the side. Still, this shouldn't be an issue for most people who rest their ring finger on the side of the mouse.

People with very small hands may have difficulties reaching the sniper button when using this mouse with a claw grip. However, if you have a medium to extra-large-sized hand and you rest your ring finger near the right button, you may accident click it because the right button overlaps towards the side. Still, this shouldn't be an issue for most people who rest their ring finger on the side of the mouse.

The Razer Basilisk Ultimate can be used wired or wireless. It comes with a USB receiver which can be plugged directly into your PC, or into the included cradle to work as an extension if your PC is too far from your mouse. If you also want to use your mouse via Bluetooth with your work station, then check out the more affordable Razer Basilisk X Hyperspeed, although its performance isn't as good as the Ultimate model.
The included Micro-USB cable is the same as the one included with the Razer Viper Ultimate, and is much better than most other Razer cables. It's a good quality cable that has a good amount of flex. It can be used to connect your mouse to your PC, or can be plugged into the included adapter to work as an extension cable for the USB receiver.
The Razer Basilisk Ultimate's click latency is excellent when used either wired or wirelessly, which is great. Even the most competitive gamers likely won't notice any delay.

Overall, the sensor of this mouse is remarkable.
The Razer Basilisk Ultimate has 11 buttons including the L/R wheel tilt, and all of them (as well as the up/down scroll and profile switch on the bottom of the mouse) can be reprogrammed with the companion software. You can also assign a HyperShift button to give you a second layer of programmed buttons.
The Razer Basilisk Ultimate's mouse wheel is quite decent and has a L/R tilt, which is nice. The scroll resistance can also be customized to be as clicky or as fluid as you prefer by using the slider switch on the bottom of the mouse, which is great.
Razer Synapse 3 is a great piece of software. You can customize every button on your mouse, save multiple profiles, adjust CPI and polling rate, and set the 14 RGB zones. This mouse also has on-board memory so you won't lose your customization settings when you switch computers, which is great.
Unfortunately, Razer Synapse 3 isn't available on macOS. While this mouse will work with default button configurations on Mac out-of-the-box, if you want to customize them, you'll have to make the changes on a Windows-based PC and save them to the mouse.
