## Description

desertcart.com: Kensington Orbit Trackball Mouse with Scroll Ring (K75327WW), Black-Grey : Electronics

Review: Definite keeper! - I've had the trackball for about a month now. I bought it to replace the wireless Mighty Mouse that came with my Mac 'cause it ate batteries like no tomorrow. VERY, VERY pleased with the trackball. It took me about a week to figure out how to comfortably use it as I had exclusively using a Wacom tablet in place of the mouse, before deciding to get some sort of mouse. The software: To start off, for those reading reviews of those complaining about the program, you CAN plug and play it. You don't actually need the program for the trackball to work. The mouse adjustments that you can make in the System Preferences will still work for the trackball. However, in order to access the additional features, you will need to download the software. It's a very easy process, just go to the website, download and install it (the instructions come in the packet). The icon will show up in your System Preferences window under the Other header. I don't know where it appears for Windows as I've only transferred the trackball between our Macs. In the trackball program, you can adjust the usual features (scroll speed, click speed, etc) and also the left/right combo click which you can set to do stuff like go back or forward. The program also allows you to choose which direction to have the scroll ring turn to go up or down. The default is set to clockwise for scrolling down. The buttons: overall, they're pretty standard in function. However, I do find that sometimes in certain programs like a Flash game, it won't always want to click on the first try, so I wouldn't recommend this for gaming purposes for games where you do need an immediate response. All other uses, I haven't really noticed any problems. I love the option of being able to set the dual click to do something :) As a first time trackball user, something else I also had to remember to do was take my fingers off the ball before clicking as I often catch myself nudging the ball when I click and then missing the spot I wanted to click. Same goes for the scroll wheel. I seem to subconsciously fiddle with that too. Trackball: No issues with it at all. It took some getting used to with adjusting from a mouse or my tablet and I found myself trying to click on the ball itself a number of times. *lol* But no fault of the device. The scroll ring: So far, I haven't experienced any of the major problems that have been complained about so far. Up till about a week ago, I hadn't gotten around to looking into the trackball's software and once I did, it made a huge world of difference with how smoothly the ring scrolled. It felt a little slow, previously to the point where it sort of staggered sometimes. I love how I can now just give the ring a quick flick with a finger and I'll be back at the top of a web page. I've actually caught myself trying to do that with a scroll wheel on a mouse at work and wondering why it just inched up instead of flying up where I wanted it! Keeping in mind of the complaints though, I have been careful with the wheel and trying not to use it when I don't feel I really need to, as not to potentially abuse it to death as I really like it. So if I'm scrolling to skim an article or search it for something, I'll use the scroll bar on the browser, which with the trackball is pretty effortless. Extras: It includes a wrist rest that you can attach to the end of the base. I didn't bother with it as my desk has a built in one. Size of whole unit: it's a decent size for me. My hand length is about 7 inches and the size of the unit allows me to perch my fingertips on the ball and comfortably roll forward to the middle joint of my fingers if I want to do one long continuous drag. I've play tested some older trackballs in stores many years ago when the majority seemed to be a lot larger, so this works fairly well. Advice: if you find yourself needing to clean your trackball, don't use Clorox wipes. It leaves a sticky residues that slows down the ball's spin. I just pulled out the ball and washed it with hand soap and water, wiped out the dust in the holder, dried off everything and stuck it back in. User troubleshooting: If you find that your hand is more tired using the trackball than a regular mouse, try adjusting your chair height. This can make a very big difference. If you have an arm rest on your chair, take advantage of it and adjust your chair height to make the rest level with your trackball.
Review: Really good basic trackball - I've been an avid trackball user since the 1990s and have used quite a few of them. I've been trying to replace my favorite discontinued model for years, and of the many I've tried I would say this is the best. Pros: Overall feel is very nice in my hand. It was broken-in within minutes (by this I mean the ease of rolling the ball in it's socket; there is typically a bit of drag or stiffness with most of the trackballs I've tried. This usually gets better over a few days' use). The scroll ring also feels nice. I would call the build quality mid-grade. It doesn't feel high end, but it also doesn't feel like junk. The wrist-rest is just a tiny bit lesser quality plastic, and I didn't expect to use it, but after trying it out it really does improve overall comfort of use. The software is simple, although there is room for improvement. Another pro for me is the ball being in the index-finger position. I really dislike models with the ball in the thumb position, but that is really a matter of personal preference. Cons: Not enough cons to impact overall rating. I would like more buttons, although that is probably a limitation of being a low-cost model, as the more expensive Kensingtons do have more. The ability to chord (press both buttons simultaneously to function as a third button) would be nice. I don't know if that is a limitation of the software, hardware, or both. The scroll ring is a tiny bit too sensitive for my liking. In summary, this is an excellent trackball for the price, and is significantly better than more expensive trackballs I have tried (I got this one for $17 during a Black Friday sale). I wish I bought a few of these at that price, because it seems like once a model becomes discontinued, the after market prices get crazy. For example, my all-time favorite is the Microsoft Trackball Explorer, which was perfect in every way. Long discontinued, they can still be found on Ebay for several hundred dollars. I may give one of the higher end Kensington models a try. I briefly tested one in a store years ago and didn't like the ergonomics, so the only reason I tried this one was because it was insanely cheap. I'm very glad I did.

## Questions & Answers

**Q: Do you have to put too much force on the left button while dragging? Do you have to put your hand in a awkward position to do it?**
A: Hi,  It's more in the pressure it takes to click the button (switch), Most of my mouses and trackballs have hair pin buttons meaning it doesn't take much pressure or finger muscles to click.  This one is pronounced, it takes more pressure which over the period of time this adds up.  I would send it back if it wasn't more trouble than it was worth to do so.   I got it so I could train my left hand to use it.   It sits in the closet now.

**Q: How do the buttons feel when clicked? Are they too stiff? Do your thumb gets tired after a long period of use?**
A: I was previously using a Logitech Marble Mouse trackball which has a much lighter click action than this unit. The overly heavy button springs are my only complaint with the Kensington.  My thumb has gotten stronger in the time I have been using it, but long periods of game play do make it quite sore. In conclusion, I like the Logitech for game play and the Kensington for web browsing.  Older users will have more trouble adjusting than younger ones.

**Q: Does it have a scroll click (middle click)?**
A: With 💩KensingtonWorks 3.1.2 for Windows 10, in Firefox, "Middle Click" does not work for ...
- "Right Mouse Button" with "Alt", "Shift", "Ctrl";
- "Left Mouse Button" with "Alt", "Shift";
- Assigning both button being clicked to be recognized as "Middle Click" is a game of chance.

"Ctrl" + "Left Mouse Button" works as "Middle Click" without help "KensingtonWorks" software

**Q: How long is the cord on the Kensington Orbit Trackball?**
A: I did not measure it, but my guess is that it is around four feet long. I got the trackball for health reasons (wrist, carpal tunnel issues). So I had never even taken the plastic twist off the trackball until you asked the question.

### ⭐⭐⭐⭐ Good, but no MacBook multitouch trackpad
*by M***E on February 22, 2010*

Trying to improve my desktop ergonomics, I raised my MacBook Pro up on a platform, purchased an external keyboard, and went searching for an external mouse. At first I thought I'd just use my iPod Touch, so I tried out four or five of the trackpad-type apps. Some were okay, but they were a pretty big disappointment coming from the MacBook's multi-touch trackpad. There were several minor annoyances like lag with some of them, but two big problems with all that I tried: (1) I found them almost impossible to drag-and-drop with, and (2) triple-click didn't work. Back to the drawingboard, I searched for an external mac-like trackpad, but wasn't impressed with what I found. Their reviews made them sound like they suffered from the same weaknesses as my iPod's apps. So I thought I'd try a trackball; back in the day, I loved my old mac laptop's trackball. I read all the reviews here, and ordered this one, the Kensington Orbit with scroll ring. Given the above history, after about a week's use of the trackball, here's what I found. On the positive side: (1) it's a trackball, so since it doesn't move around on your desk you can find it immediately without looking. (2) While some reviewers were disappointed with the ball's size or weight, I found them to be great. (3) I can accomplish drag-and-drop, no problem. (4) I can triple-click, no problem. On the negative side: (1) There is simply no way to scroll horizontally - the scroll ring only controls vertical scroll. I knew this when I ordered it, but hoped I wouldn't miss it; it has turned out to be as much of a pain as I feared. Two-finger scrolling in any direction on the MacBook's multi-touch trackpad is a godsend. (2) The vertical scroll wheel works, but the resulting scrolling on the screen is, in comparison to the multi-touch trackpad, very choppy, hard to control, and disorienting. This came as a big surprise to me after all the positive reviews, and I hadn't realized how smooth and controllable the multi-touch trackpad's scrolling really is. I don't attribute this to the scroll ring itself being sticky (though there's a bit of scratchiness if you move it fast and far), but rather to how the motion is being translated into on-screen scrolling. (3) Because of the position of the cord, the layout of the buttons, and the overall size of the device, you really can't position it directly in front of you, just under the space bar (the position closest to your hands and most like the position on a laptop). One of the consequences of this is that you can't really use it with two hands at once as you (at least, I) do with the multi-touch trackpad (or even the ancient mac laptop's trackball). I generally drag-and-drop by clicking with the left hand and scrolling with the right, and I select text in a similar fashion - it is much faster and more accurate; but this is highly awkward with the Kensington because it has to be off to one side of your keyboard. Looking at the device, I'm convinced they could make it significantly more compact and if it was wireless, too, then it could work well in front of the space bar. I had decided to avoid wireless, since I didn't want to be changing batteries; perhaps that was a mistake, but in the case of this device even that wouldn't be sufficient. On the whole, this is a fine and functional device - I expect that many people would find it a vast improvement over a mouse, or several other options. But it doesn't measure up to the MacBook multi-touch trackpad in terms of selecting text, dragging and dropping, or horizontal scrolling. If you're on your computer all day every day like me, doing that stuff quickly and accurately really makes a difference.
