Kensington Orbit Wireless Trackball with Scroll Ring - Space Gray (K72675WW),Black/Grey

Work great and not the highest spec but that not what its for. I have a gaming mouse for that purpose. this allows my wrist to rest.

I've been using this for three years and it works great. I use a laptop and work remotely, so I literally tote it around and take it out almost everyday. I use the trackball because I hate trackpads, even the Macbook Pro pad. A mouse is fine, but it doesn't work on an uneven surface. Durability: The only durability issue I've had is with the little rubber feet on the bottom. I re-glued them (E6000 Premium adhesive works) about two years in. Otherwise, it never acts up. I also keep mine in a general purpose case, so it isn't rattling around in my bag. Mouse Movement: Ball movement is smooth. I think it's much smoother than the Logitech M570 that I used before. It is important to keep it clean. Snacking on slightly greasy food with my right (mouse) hand will cause it to feel janky. Wiping clean usually solves the problem. The ball pops out easily for cleaning, and the little contact points will get gunked up, so I clean those regularly too. The scroll wheel works fine too. It felt a little "loose" at first, but I don't notice it anymore, and I use it constantly. Accuracy: A trackball isn't quite as accurate as a mouse, but I haven't used a mouse in so long that I don't really notice it. I found a "speed" setting on my computer that lets me move quickly across the screen but let's me land with some precision. I doubt I would use this for precision gaming or graphic design, but I can fit the cursor between two characters with no trouble. Weight: The Orbit weighs 187 grams with a battery, so it feels light but not cheap. More importantly, the ball itself has a decent heft. I would rather it was a little heavier and had a little more inertia (like a Missile Command trackball), but it's fine. Fit: When I first got this, I thought it was way worse than my M570. The M570 is very natural, scrolling with your thumb and clicking (and using the scroll wheel) with the index and middle finger. The way I use the Orbit, I scroll with my index and middle finger, left click with my thumb, use the scroll wheel and right click with my ring finger on my right hand. This felt really unnatural, almost painful, at first. I was writing quite a bit in SQL and using Excel, so quickly navigating was important to me. So I stuck my Orbit in a drawer for a few months and basically thought it was a failure. But I pulled it out a few months later when I was without a trackball, and after a few weeks, it felt totally natural. Now it's all I use. I think a weird trick that helps is that I roll it with my fingers and then barely lift them off the ball when I go to click. Clicking with my thumb while my fingers touch the ball almost always wiggles things around too much. Connectivity: I use my Orbit with my Macbook Pro and just pair via the built in bluetooth. Before that, I used it with a Windows notebook for a few months without trouble. I never really have to fuss with it. I switch it on and it works right away. Battery Life: I use this pretty intensely everyday, but I probably only change the batteries a few times a year. I don't keep track, but I'm pretty sure it's at least three months in between changes. And I don't have to repair or fuss with it after battery changes. In summary, I this is my main input device and I'm very happy with it. It does everything I want and causes very few problems.

Aunque inicialmente vi grande al trackball, resultó ergonómico, realmente muy cómodo de usar. Tengo curiosidad por ver la duración de los switches (clicks) Así que actualizaré la opinión dentro de unos meses.

I have been a trackball user forever. So many advantages over the regular mouse, the primary one being, if you’re doing really fine work on a graphic, it’s pretty much impossible to click the left (or right) button without moving the mouse a tiny bit. Trackballs don’t have this issue. Simply lift your hand off the ball and the cursor ain’t goin’ nowhere. So I’ve used a Marble Mouse (which is not a mouse, it’s a trackball) for a really long time. In fact I have several of them because,… in case. It has what I look for: + finger driven—not thumb driven. My thumb just doesn’t have the fine motor control + ambidextrous. I don’t use it with my left hand. But I could. + comfortable. A place to rest the rest of my hand while my fingers are working the ball. + big ball. Preferably golf ball size or bigger. I tried the tiny ball versions and I found them most frustrating. So if the Marble Mouse is so great (which it is), why am I changing? One word: wireless. For some reason the Marble Mouse does not come in a wireless version (either BT or dongle). Wire to USB-A only. I researched if there was a way to convert a wired trackball to a wireless one and, well, there is. But it’s way too complicated. So I looked for a wireless equivalent and came up with this Orbit. It is great. Good sized ball, comfortable, smooth scrolling, responsive. It even has a scroll ring (the Marble Mouse has up and down scroll buttons). The scroll ring is better. Also comes with the Kensington mouse control software (though your Windows Control Panel/Mouse does most of the same functionality). This is a really good pointing device and I suspect my collection of Marble Mice will now, after a storied career, be retired with honor.

Solo un par de días después de que cerrara la ventana de devolución, el trackball dejó de funcionar con su nanoreceptor wireless. Sí funciona con el BT pero necesito las 2 conexiones porque tengo 2 computadoras. Ahora ya no me sirve. No lo volvería a comprar.

I was having issues with my thumb so this really helps. I switched the left click to the right click so I rarely use my thumb at all. My only complaint is that the click is a little bit loud.
