Perixx Perimice-517 Wired Trackball USB Mouse, 7 Button Design, Build-in 1.34 Inch Trackball with Pointing Feature

Works as 8t shoud

Been using it for a couple of months now and it hasn't disappointed. I have felt an increase in pain relief in my wrist because of the angle and use of the thumb for moving the tracking ball. If the computer is idle momentarily, there will be a slight delay when returning to the trackball. Also, be very careful when cleaning the trackball and its cavity. It's very sensitive and any small amount of debris will affect the tracking. Other than that, it is definitely one of those 'non-brand name' golden finds.

I'm going out of my way to write this review, and tempted to keep it a secret, but I feel obligated to save others the time and money I spent in my search for a "gaming-worthy" trackball mouse. Aside from comfort and design, LEDs and other bells and whistles, most "pro-gaming" mice have two crucial settings for performance and accuracy; polling rate (the rate at which the mouse position is sampled) and DPI (the resolution at which the sampling occurs).Few trackballs offer adjustable DPI, and none of them offer higher polling rates, which makes the DPI settings almost useless in most cases. Every trackball mouse I've tested polls at a (default) rate of about ~128Hz (at best). One can sometimes "hack" overclocking the USB port via 3rd party drivers (though I do NOT recommend doing this!), but it's just that; a hack.I have used trackball mice as my "secret weapon" since the days of the original Doom / Quake and the beginnings of eSports. They are (were) far superior both in terms of comfort and control. However, for whatever reason, perhaps influence from eSports companies / sponsors, trackballs have been left behind in terms of performance. I own perhaps a dozen trackball mice; Including Elecom, Sanwa, and Logitech, including the original Logitech Trackman (still the best of the bunch). Even the latest and greatest of the "performance" trackballs lack basic performance capability and some seem to try and compensate by offering additional bells and whistles that compromise the simplistic design (just try gaming with an MX Ergo while you press the right mouse button a little too hard to zoom in and accidentally tilt the mouse from zero to twenty degrees and your thumb slips off the trackball and hits the DPI switch from normal to ultra-super-high DPI). It's the difference between "frag or be fragged" in the heat of battle.Where accuracy intensive weapons are concerned (e.g. Lightning gun or Rail gun in Quake), the polling rate is a critical setting to help ensure your mouse is polling fast enough to keep up with the game FPS (frames per second) which is dependent upon your GPU and Monitor refresh rate and DPI as well. It's a delicate balance, and the last thing you need is laggy input devices. If you're serious about gaming, these settings are nothing new. Again, though, for whatever reason, trackballs have been left behind, and companies have yet to enable the same performance capabilities for their trackball mice offerings as they do for their "pro-gaming" mice offerings... until now.When I plugged in the Perixx, it was immediately recognized by the OS (Windows 10 Pro x64) as Full-Speed USB mouse. This means I'm getting nearly twice the polling rate at ~256Hz. This is still nowhere near the 500-2000Hz pro-gaming mice offer, but this seemingly small change in polling rate make a _huge_ difference in games in terms of smoothness and accuracy.The Perixx trackball is flatter and wider than the Logitech offerings (which I do like for comfort). However, the flatness does seem to keep one's wrist straighter, and the wideness provides extra support for your pinky finger. I've been playing 6 to 8 hour tourneys with little to no fatigue, and am very pleased by the comfort design.The Perixx trackball has less trackball surface / exposure than the Logitech M570 or original Trackman, but about the same as the MX Ergo. I tend to prefer the larger surface area as this allows for more precise “full turns” (0-180 degrees) in game. Also. it seems the ball bearings (on which the trackball sits and spins internally) are a bit too flush with the internal plastic trackball housing. Occasionally I'll find myself pressing a bit hard on the trackball and it gets stiff in the socket. This is my only complaint, and the only reason I can't give five stars. I did buy an extra "matte" finish trackball, so perhaps I'll try different balls in the mouse to see if this problem goes away, but it is relatively minor issue and may go away with some use (mouse "breaks-in"). The Perixx is still by far the most accurate of the trackball mice I've used, and I have seen immediate improvement with use of certain weapons in games.The Perixx buttons are responsive (low profile / short travel distance) with decent "click" feedback. It has the typical wheel and forward / back buttons, but they did the mouse a great service by keeping it simple and not bloating it with too many buttons or odd positions or bells and whistles. The mouse also has a 400/1000 DPI switch, which I probably won’t use in game, but is far better balanced than the drastic 512/2048 change in the MX Ergo and could potentially be used (with practice) for Zoom or precision aiming. And the standard positioning of the DPI switch (behind the wheel) means no accidental in-game DPI resolution switching.I have hoped and prayed (and even begged companies like Logitech and Razer) for a decent pro/gaming trackball mouse with no answers... until this mouse landed on my doorstep. As an experienced software / hardware engineer I even offered these companies my services to fix these problems or create new solutions for them, but it would seem they don’t consider anything to be broken.The design and engineering of the Perixx trackball mouse, along with (simply taking the time to implement) Full-speed USB firmware for better polling rates and performance, puts this "value" trackball far above the vast majority of more expensive "performance" trackballs (which are really anything but).

I just got this wired trackball mouse after reading lots of reviews and comparing with some others in the same price range.Pros - Comfortable under the palm of my hand and does the jobCons - As expected after reading reviews there is some "slip" in the tracking, especially when trying to make small precise movements. I found that increasing the DPI and slowing the pointer speed down helped with the problem some.Since I have only used it in the office so far I can't speak for how it works for gaming.I am thinking of buying the Matte finish ball for $10 to see if that helps with the tracking issue.First Impression: For $25 it does the job and for office work I can deal with the little "slip" in tracking, and even if I have to buy a matte ball for an extra $10 it is still cheaper than most of the other wired trackballs available.UPDATE 4-27: After using the mouse for a few weeks now I have increased the pointer speed back to default and it seems to be working properly. Either the mouse needs some break in time or I just needed to get used to a trackball again. Still no complaints.

The review by D. Duncan led me to believe this would be good. Great, even. But his or her review is a total sham.Uhg, I just wanted a replacement for my wireless Logitech trackball mouse. The same, but WIRED. Cuz I'm having signal issues.This was not the answer. The trackball sticks (actually gets slightly better as it gets dirty, ironically enough); moves half as far vertically as it does horizontally; either doesn't move the cursor at all, or, in the same small amount of movement of the ball, the cursor teleports over a bunch of pixels to it's destination. And at other times, it's buttery smoothe and precise, so it's not the computer's mouse sensitivity settings. It's just garbage. Even trying to use the click-scrolling of the mouse wheel is a challenge, cuz it doesn't like to click in as easily as it does on good mouses. And lastly, the two DPI settings are either way too slow or way too fast.I tried to fix my signal problem with my Logitech mouse sending the the click signals twice, and this fixed that, being wired and all, but it ruined literally every other part of the mouse aside from the pleasant form factor. That's the one good thing about this. Would have also been for the purple ball, but mine came with red instead.
