Perixx PERIPAD-704 Wireless Touchpad, Portable Track Pad for Desktop and Laptop User, Large Size 4.72x3.54x0.74 inches (Wireless), Black

The touchpad is exactly as advertised. Very basic features, and plug & play. The gestures work fine; however, I only use double finger up and down for scrolling and single tap for click.The left and right buttons have a nice clicky snap to them that gives it nice feedback whenever you interact with them. And the surface area your fingers interact with to move the cursor has a slight texture but nothing significant. It's not smooth like glass but not rough like sand paper.For the price it meets my expectations. My hands are quite bad and I can't use a traditional mouse. I prefer this over a trackball style setup and would recommend it to anyone in my situation.I'll admit the one thing I forgot is that there's no middle mouse button, but that seems common among all trackpads and just highlights my oversight during pre-purchase.

My specific use case for purchasing and using this device is to use it on a Chromebox. Overall, the device works as advertised. The surface has a very light sandpaper-like feel to it that helps your fingers to move and scroll the touchpad. If Perixx had decided to increase the dimensions of this touchpad by 25 to 30 percent, I think this would be a much more popular touchpad to use. In its current state, the touchpad is functional, but you will discover that your fingers want to be accustomed to a larger touchpad space.

There was a prolonged period in the 90's and early 2000's I think, when I actually preferred touchpads to other pointing devices. Mine were high quality wired models that reliably performed all basic functions in Windows 98 forward. I found them to be straightforward, intuitive and natural to use. Somewhere along the way I was seduced away from touchpads by wireless trackballs and mice, which I've used interchangeably for the last 15 odd years. However, as I've aged I've acquired some health issues that cause me to unintentionally press mouse/trackball clicker buttons, which is both annoying and counterproductive. That probably wouldn't happen with good old touchpads, I reasoned, and proceeded forthwith to buy two -- this Peripad-504 and a Keymecher 620-U_MAX as well. As an experienced touchpad user, I'm disappointed by both. They have decent build quality, but don't function well or consistently. They just don't register taps well, and even the left/right click buttons don't work right. Whether those respond at all depends on where and how hard they are pressed. They should work whenever and wherever they are pressed, but no. Touchpads are simple widgets that should function correctly every time, especially considering the power and sophistication of what they are plugged into. There shouldn't be a learning curve. However, these don't even work as well as the ones I used 2 decades ago. I don't know whether I'll keep or return either of them at this point, but either way if you decide to get one, be aware that they have issues.

Multi-touch and scrolling are a bit fiddly. (This is not Apple-class.) But it otherwise does exactly what I need it to do. Nice and big and able to be wired into a sim rig. Works great!

I'm using it on a laptop running Linux (NixOS, KDE Plasma) .I love having two-finger gestures available at my desk. It worked on without having to install or configure anything, which is great. But it's practically unuseable:There's like a half-second of delay between when you start a gesture and when the page starts to scroll. The feedback is so sluggish that by the time you take your finger off the pad you've already scrolled past what you wanted to see. Pinch and zoom is similarly too hard to control, although I'm not sure latency is the problem there. And for pointing it's much harder to use than the mouse or the trackpad built into my laptop. As a result I'm keeping the mouse plugged in; I use the trackpad to scroll pages and the mouse for pointing.

This touchpad perfectly suits my needs and surpasses my expectations. I use it with my Windows 10 Dell laptop (docked, lid closed) with an external keyboard and mouse because I also wanted access to a touchpad. The Peripad-504 was immediately recognized as a “mouse” upon connecting with no additional action required. It works wonderfully. Since I also use a Mac with a Magic Trackpad (which I absolutely love), and the scroll directions on Mac are opposite the scroll directions on Windows, I found some instructions on the internet for how to edit the Windows registry to “FlipFlop” the scroll directions for the Peripad-504 to match my Mac. Extremely happy with this touchpad.

It sure looks like a touchpad, but plug it into Windows 10, Ubuntu, Fedora, or Clear Linux and it has the firmware of a mouse. You cannot disable tap to click or change any settings you could change with an actual touchpad. It is a shame, because it appears you cannot get a regular touchpad with buttons that is not just a glorified mouse. I have decided to get an actual touchpad with dedicated click spots that isn't just a glorified mouse.The touch surface is kind of rough. The mouse moves when you take your finger off the surface unlike the laptop touchpads I am used to. The mouse movement is not super smooth, but smooth enough that it works. It is not very ergonomic due to the tap to click. It registers taps when you try to make a quick mouse movement, and if you are shaky or like to rest your finger on the touchpad, you will find this touchpad unusable.

I bought this device mainly to work at night and not bother my wife with my constant mouse-clicking. This touchpad does the job perfectly, recognizing several finger gestures that make it versatile for scrolling, selecting, zooming, etc.
