In an era where every gaming peripheral designer is trying to include more & more features – some that affect game play with new features or options, some to make the mouse look more “sexy” while sitting idle on your desk – the Lexip Pu94 tries to accomplish both. Unfortunately, it misses the mark with features that, while interesting and designed to “gain an edge”, directly other critical functions.
The Pu94 (the elemental symbol and number for Plutonium) claims its edge by adding “2 joysticks” to the mouse itself – one an actual joystick on the left side where traditionally a gaming button is located, and the second is the whole top shell of the mouse housing which rocks on an axis over top of the mouse bottom. The intention here is to give you additional control options in various programs, not just games but also professional applications like those used for CAD drawings and photo/video editing. For example, in CAD programs you can use the side-mounted joystick to pan around an image without having to do a more traditional CTRL+click+mouse move to pan a drawing in 3D.
The multiple control options are guided by “Profiles” which can be downloaded or hand-created by the user in the Lexip Control Panel software (required installation otherwise this won’t do anything more than a stock $4 mouse on the school supplies aisle at Safeway). The profiles are detected for the program you’re launching, and you can have a profile for individual apps (Chrome, IE, FireFox, Word, PowerPoint, specific game, etc.) or “All Software” (anything else that doesn't have a program-specific profile). So what the joystick or buttons do in 1 program can be different from what it does in a game or other program. This gives you nearly unlimited functionality for different movement or viewing options.
Other control surfaces are similar to other mice – scroller wheel, back & forward side-mounted thumb buttons, middle finger button just below the scroller wheel.
The mouse moves INCREDIBLY smoothly across a surface thanks to 6 ceramic pads on the bottom (which can also be purchased separately either to replace the Pu94 pads or to use on your non-Lexip devices).
Movement speed is controlled with the Control Panel software, easily moved from 10-12,000 DPI with a slider, and can be controlled per-program (“Profiles”). I found the ability of the Control Panel software to lower the speed of the movement when using Photoshop helpful, giving me slower mouse movement & more control over precise editing jobs.
Despite having a separate cord to connect to your computer, it is NOT wireless/battery operated. You have to use the included micro USB cable to hook it up, which begs to question why add the weight of a removable cable connector instead of just hard-wiring the cord into the mouse body?
MISSING THE MARK:
While adding 2 additional “joystick” control surfaces to the mouse sounds like a great thing, it wasn’t executed well.
Starting with the thumb/side-mounted joystick: When holding the mouse normally, the joystick is too far forward to reach with your thumb. This requires you to slide your hand forward on the mouse, which then places your 2 “mouse fingers” over the outer frame of the mouse, preventing you from using the mouse buttons unless you curl your fingers into a non-human pose. (See photos). Additionally, the “push in” button of the joystick is so hard to push there is no way to activate the button of the joystick without directly changing whatever situation you have arrived at using the joystick in the first place.
The outer frame around the front edge of the mouse should have been removed. Had they removed that frame and made the left & right mouse buttons go all of the way to the edge, the issue with moving your hand forward on the mouse to use the joystick would have been completely avoided.
Additionally, the “rocking” of the mouse shell in your hand can cause inadvertent movements. I used the rocking for controlling “look around” moves in FPS games, giving me the ability to look left, right, up, and down without actually sliding the mouse on the surface. All I had to do was rock my hand in various directions. This was WAY cool. However, when you go to move the mouse, unless you have the inhuman ability to keep your wrist locked, as you move the mouse around so does the rocking of the top. So let’s say you’re trying to move in an FPS. Moving the mouse forward results in a backward pressure on the rocking joystick, so as you’re running forward your find your view drifting up. This can be somewhat controlled in the Control Panel by adding what they call “dead zone” – a percentage of movement from center that is ignored. But you find yourself reaching a point there is more dead zone than usable area, negating the feature.
The Control Panel software, which again is required to get anything more than basic left & right button functions from the mouse, features a plethora of spelling errors. While this doesn’t necessarily affect its use, it is indicative of poor quality control. “Profile” is again & again spelled “Profil”, which I believe is due to the fact this is a French company manufacturing it and they never bothered to have someone spellcheck it. They also refer to “Microsoft Window” in the software, again something minor but shows they didn’t bother to do basic checks on the program before sending it out.
Control profiles for new games or applications can (in theory) be downloaded from Lexip’s site, but ONLY from the European site. When you go to “Profils” and choose “New Profil” > “Download a Profil” you are launched to Lexip’s website, which immediately warns that you’re using the European site & asks if you want to use the North American site. When you say yes, you get what looks like the same site, but there are no profiles on the NA site to download. You have to go back to the European site to get the new profiles. Again, just bad UX design.
I also caught the mouse “reinstalling” itself several times during use, even though nothing was disconnected or other changes made. It did it while the mouse was sitting idle, so I was never able to see if this was something where connectivity was lost that would have jammed me up in a game, but clearly there is an issue with the mouse-to-PC interface, whether it’s the connector, cord, or software.
SUMMARY:
The Lexip Pu94 touts itself as the “most funded gaming mouse in Kickstarter history”. I think people, specifically gamers, are always looking for that extra edge in their online play, and the gimmick of a couple of extra control surfaces being added attracted supporters. But the location of the oddly-placed joysticks ends up being just that – gimmicks. In the end, the joysticks became nothing more than distractions that I found myself not using, resorting back to use of this mouse as a simple mouse.
