Logitech Ergo M575 Wireless Trackball Mouse - White

I'm not a newbie to the trackball mouse. Years ago I had a wired Logitech trackball but found, over time, the ball lost its smooth movement; the ball became sluggish and cleaning it didn't help, so I went back to the traditional mouse. Recently I decided to give the Logitech trackball another shot and scored the ERGO M575.I've always liked the trackball setup, it's definitely easier on the wrist and hand. With a trackball, you don't need the desktop "real estate" needed with a conventional mouse. The "metalflake" looking blue ball has a nice, smooth feel to it and I find it very accurate and easy to use. I hope as time passes, the ball stays as easy moving as it does now. If you've not used a track ball before, it may take some getting used to, so give it some ... MoreI'm not a newbie to the trackball mouse.

If you've not used a track ball before, it may take some getting used to, so give it some time before you pass judgement. A big component as to how comfortable ...or not ...this ERGO trackball is going to be has a lot to do with your hand ...and how it fits the M575. Strongly suggest you try it on for size at your local BestBuy store. For me, it fits fine and is a lot more comfortable than a traditional mouse. But my hands aren't that big; a size "medium" in work gloves if that helps.The ERGO M575 offers both wireless and Bluetooth connections. I found the wireless connection to be a bit sketchy. I have a thin profile iMac Pro ...and all the USB ports are on the backside. The M575 had a very hard time maintaining a good wireless radio connection with the receiver plugged into the back of my iMac. The thin profile iMac is made of a lot of aluminum ...and probably blocks or reduces the signal strength to the USB receiver. The M575 would work sometimes and at other times get jumpy or unresponsive; it wasn't 100% reliable in its function. I decided to try the Bluetooth connection and that has worked well; I've been running it via Bluetooth for a week and it's working flawlessly. Some have commented on having a wired option and, given the potentially poor signal strength and reception of the wireless connection, having a wired option makes sense. Depending on the location of the desktop, the location of the USB port and how much metal is involved, will determine your success in using the wireless connection. IMHO, for desktop style computers without Bluetooth, it would be best to have a key board with a USB port to plug the M575's receiver into. I tried plugging the wireless USB receiver into a USB hub, to move it from behind the iMac, but that didn't work well either.The functions of the buttons and scroller of the M575 trackball are identical to a regular mouse. You can get free downloads of Logitech software to help customize the M575 potentially offering a higher level of customization.Overall I'm very happy with the ERGO M575 trackball mouse. Like every other Logitech device I've purchased, it is well made and exudes a level of high quality. The M575, for me, is definitely more comfortable than any traditional mouse I've used. It's weak point seems to be the wireless connection; the location of the USB receiver is critical in how well the M575 reliably connects and functions. Bluetooth works well in lieu of wireless if your computer has it. If you don't have a Bluetooth option then having a keyboard with a USB port would be best IMHO. Otherwise you'll have to take your chances on reliable reception. I dinged it a star for the iffy wireless connection and no option for a wired connection; this is one mouse that needs a tail.

When you Tweeted that you fell into the Bill Ackman camp on SBF, I scratched my head. Now it all makes sense. I thought how could guys as shrewd and cut throat as O’Leary and Ackman be giving SBF a pass and why would they going out of their way to publicly give him the benefit of the doubt? I see the strategy now. There is so much information investors need in order to straighten this out so that they can report losses properly and start the process of getting their money back. It’s counter intuitive to put SBF or any of his team any more on the defensive than they already are because you might need his/their cooperation to find some of these funds and there’s a real chance that without tht cooperation you may never find a portion of them again. But once you know ... MoreWhen you Tweeted that you fell into the Bill Ackman camp on SBF, I scratched my head. Now it all makes sense.

But once you know what you need to know to line up the path to recovery, it’s going to be knives out! Full shark mode! SBF made a lot of cunning and smart people look dumb. I think he’s going to pay the price for it and I think you just might be leading the charge!I recently purchased an ergonomically correct optical mouse with a ball cursor and have been using it for work in Excel. I must say, I am thoroughly impressed with its performance. The ergonomic design fits comfortably in my hand and reduces strain on my wrist during long periods of use. The ball cursor allows for precise movements and makes navigating spreadsheets a breeze. Overall, I am very satisfied with my purchase and would highly recommend this mouse to anyone looking for an ergonomic and efficient tool for working in Excel.Logitech has a few ergonomic mice with ball cursors that you might be interested in. One of them is the Logitech MX ERGO Advanced Wireless Trackball Mouse which is crafted for the shape of your hand and built for fast and precise tracking. It has a unique 0 or 20° tilt angle that allows you to adjust your hand and wrist posture to conquer those lengthy decks and spreadsheets with ease 1. Another option is the Logitech ERGO M575 Wireless Trackball which has a sculpted ergonomic shape and smooth, responsive thumb control 2. Both of these mice are designed to minimize movement and maximize comfort while using them.

My initial reaction to this mouse was a bit of trepidation. I was curious, though, and I knew I wanted a Bluetooth mouse for my work computer, so I decided to give this a try. After getting it all connected, I was intimidated by the way the track ball moved and I was convinced I had made a mistake; however, I vowed to just give it a try. Well, within just a few hours, I was converted, and I had purchased another one for my computer at home.It's a great mouse, it really is much easier to use than a traditional mouse (once you get over the learning curve which, truth be told, wasn't that steep for me.) I adjusted to the track wheel on the side very quickly and now when I use a regular mouse, it feels so awkward, having to pick up the mouse to move the track wheel... ... MoreMy initial reaction to this mouse was a bit of trepidation.
