Precision Gaming Mouse Round-Up: Tesoro, Corsair, Logitech

The Tesoro Sagitta Spectrum posesses the most non-descript look of the three mice we are looking at today. The top surface is a matte black, soft touch plastic. The sides and front consist of a smooth glossy black plastic. There are two independently controllable LED lights. The first is in the scroll wheel and the other lights Tesoro's logo under your palm. The bottom side of the mouse features two long and narrow PTFE skid pads for smooth tracking with little friction.

The Sagitta is the largest of the three mice by a hair. Ergonomically, it isn't unlike Razer's Deathadder. It features a somewhat conically curved body that is thickest just under your palm rather than between your first and second knuckle as with the Deathadder. The left and right mouse buttons flare slightly under your fingertips, keeping them securely centered. The left side has a bit of an indent to catch your thumb which provides good control even when claw gripped.

All of the Sagitta's buttons provide very solid and slightly heavy tactile feedback. The forward and back buttons sit just above the thumb indent and can be depressed by leaning or rolling your thumb upwards. The DPI toggle button sits just behind the scroll wheel but doesn't seem to get in the way. Despite the greater force required to depress any of the buttons, they all have very short travel distances so spamability is not hampered.

The mouse itself feels fairly light weight. This makes it easy to precisely jump to a desired position for superior positional mouse control. Tracking moving targets, while still good, could benefit from a little more mass. What weight it does have is centered under your palm so, naturally, palm grippers will get the most control out of this mouse. Claw grippers will feel as though the back of the mouse lags behind movements especially if they utilize more of a fingertip grip with their palm entirely off the mouse.

Tesoro offers the aptly titled Sagitta Spectrum software to fine tune the mouse. Overall the program is very easy to pick up and use even if it doesn't offer the most robust customization. The program is organized into four tabs: Assignment, Performance, Lighting, and Macros. Profile selection on the left is persistant through the first three tabs with macros being profile agnostic.

The Sagitta is limited to 5 independant profiles. These can be selected manually in the program, toggled via an assigned mouse key, or set to automatically take effect when a desired program is launched. For instance, in most first person shooters the forward and back buttons don't do much of anything so you can configure the software to detect when CS:GO or Battlefield are launched and automatically apply your FPS profile which ditches back button functionality in favor of a sniper button while also adjusting to your favorite DPI settings and begin flashing your gaming clan's colors.

The performance tab allows you to configure the usual suspects such as DPI, Scroll Speed, and Polling Rate, but also let you configure some smaller quality of life settings such as lift height (in millimeters), snapping angle (for photoshoppin'), and the amount of acceleration. This sensor, like most mice, isn't good enough to completely eliminate dreaded mouse acceleration so the ability to at least fine tune its impact is appreciated.

For lighting, you get two zones which are independently configurable. Zone 1 is within the mouse wheel while zone 2 makes up the logo on the palm rest area. Available effects range from always on to breathing to a cycling rainbow, all with full RGB 16.8M color control. Unfortunately, there is no option to alter the rate of color changes if that's your thing.

The Sagitta Spectrum's infrared sensor tracks exceptionally well on the Corsair MM400 gaming mat. There is very little noticeable mouse acceleration even at default settings and the long skid pads do a good job of alleviating friction while moving. Stepping down to my well loved XTrac Carbonic Gaming pad still sees pretty good, but not perfect performance. In particular, slow mouse movements begin to slightly jitter, but not enough that you would notice unless you are specifically looking for issues. Unfortunately, the Sagitta decided it would not track on my wood laminate desktop at all but surprisingly does work on denim with a little hesitation. If you need a mouse that will perform on a variety of surfaces we suggest you keep looking.

As alluded to above, this mouse excels when you need to click a particular point on the screen so it is an easy recommendation for RTSes, MOBAs, or any other isometric perspective games. In shooters, such as CS:GO, this carries over to an ease of "snapping" to a target. Target tracking is not bad by any means, but it isn't the best we've seen. The mouse is susceptible to your own hand jittering slightly as you move because of its relatively low mass and high center of gravity.
