Really good while it lasted. Left click button started doing the infamous double-click problem that these mice are known for about 2 years after purchasing. Everything else still works just fine, but the double-click problem makes it practically unusable. Other than that, this is my favorite mouse by far. Love the precision you get with the trackball and the ability to seamless switch between two computers. Perfect if you have a small space.

My last roller mouse took a dive, so I upgraded to this one. It works really well for a small area, since you don't have to move it across a pad. The slow button feature makes it great for graphic editing. Rechargeable battery last for well over a week with heavy use. I've been very happy with it.

Pros: Can be postured to be more ergonomic and comes with an app. Posture remains with the strength of a magnet, very effective. Completely wireless. Battery lasts. Bluetooth connectivity without dongle is beneficial. Cons: Prior version had a stow away for dongle, however, this version does not.

I've been using trackball mice since I was a teenager, and never went back, even after computer gaming went mainstream and gaming mice became prolific in the market. This one is solid, and the adjustable base allows a user to change the angle their hand is resting on the mouse to the most comfortable angle. Unless it fails, I would easily use this for the rest of my life!

Really wanted to like this trackball. I've been using Logitech trackballs for more than 25 years, and it's the only way to go. I was very intrigued by other reviewer comments about how it was good for large hands, which I do. For all the previous trackball models, my hand 'hovers' over the trackball. This was a new experience being able to actually rest my hand on it with the MX Ergo model. However, the deal-breaker for me is that there is a subtle change in the placement of the forward/back buttons with respect to the ball and/or scroll wheel. I use the 'back' button A LOT, and discovered I had to bend my finger quite a bit more to press it, when compared to the older version. It was nice to try it, but alas, I had to send it back for the discomfort it would cause.

This DEFINITELY works for me. It's wireless...a huge plus for me. I have big hands and this is a plus as well for users such as myself. I like the options of being able to tilt the mouse. This just works for me!!!

This is an awesome mouse hands-down. I happened to get it used for half price missing the bottom tilt plate. In a separate purchase I got the plate for cheap to complete. I control two separate computers easily with the switch. If you install the logitech software you can easily manipulate all the various button functions to your needs. I love it for the Mac because I hate the gesture mouse and including horizontal scroll. The mouse sits like a brick with the bottom plate and I have no use for the plus versions extra tilt angle. I also love the precise button by the thumb wheel which once youve gotten used to it you can control the Percision and set the options speed for your mouse to make it work for the resolution of the computer so that one swipe of the wheel gets you from the left side to the right of your display.

Good quality, an ergonomic marvel and a must have after shoulder surgery and in a sling. Ignore everyone else’s comments that it takes a while to get used to, I was working in minutes.

This is an awesome trackball. I've been using the Logitech trackballs for years, and this is a really nice update and upgrade from the older models. Plus, I love the "Plus" part of this, which is a stand that further elevates and rolls the entire unit outward to get a really natural feeling; you can remove it if you don't like it. The driver to customize the buttons is also quite nice. Overall, if you're looking for a trackball that you control with your thumb, this one is very tough to beat and is worth the price. Oh, and it's rechargeable, so no more AA batteries to include. It doesn't have a place to store its dongle, but that's quite acceptable. The colors look even better in person. The scroll wheel is well built and feels great.

It took a while to get used to using the scroll ball but after about a week it was seamless. Only thing I wish this product had more shortcut keys.

I needed an ergonomic mouse, but wanted a trackball as I had been having pain in my wrist with a normal ergonomic mouse. The mouse connects easily to my dell laptop work computer and has been easy to use. I don't have the wrist pain anymore since switching out my mouse. I have two of these, one at home and one at work. I'm able to use one dongle for both and have no issues transitioning. Definitely worth the money. If my trackball starts to get a little slow or "sticky" then I just take it out and clean the ball and the inside well where it sits. This does the trick and works perfect afterwards.

I bought this device to aid in relieving my carpal tunnel symptoms. So far it has done exactly that. I am able to manipulate the track ball with little to no pain in my hand. Thank you Logitech for developing an ergonomic mouse that is easy to use and painless to operate.

A great product! The old roller ball mouse quit and replaced with a new one Wife uses laptop in her chair and this sets on the arm of her chair. Recommend a great product.

I bought this trackball as a replacement for the previous model and was very impressed. Definately worth the upgrade. It is much more precise and the feel takes a bit getting used to if you have used the previous version, but is way more ergonomic.

Great Ergonomics. Because it has a rechargeable battery in it, and it is sealed, do not lose the charger cable... Really it is a mini USB, but just be aware.

Love it! I use it to run 2 different computers, connecting to one by Bluetooth and the other with a USB receiver. The adjustable nature of the base is really nice too.

I use this trackball mouse daily at work, spending 8+ hours at the computer a day. The adjustable angle is great for ergonomics. The trackball itself is easy to move, and gives a good balance of precision, comfort, and ease of use. Enjoy it and think it's been worth the price.

I've been using trackballs for 30 years with games and various drawing programs including CAD other types of engineering software. Logitech managed to make the M570/M575 just a little bit better. While cordless, it becomes corded for a while until the battery recharges. Then it is good for several weeks again. The additional features are a bonus. The slow mode is great for doing fine control in drawing programs and the computer switching allows controlling both a laptop and a desktop with one unit.

The MX Ergo trackball is the most comfortable and flexible trackball available. Logitech has done a great job providing multiple methods of customizing button options for multiple apps. I'm very pleased with this purchase.

The variance in different degree settings for every user to the easy switch over between Bluetooth devices is user friendly and easy to use. Great product for those having wrist issues. Mouse button features are great especially the precision button.
