Logitech Ergo M575 for Business Wireless Trackball Mouse - Graphite

This is the best trackball mouse. It’s the only one I will use.

Excellent and well-made mouse for people with medical issues. I had a shoulder problem; this mouse helped me heal faster.

These are my favorite mouse devices. One just places there hand over the top and control curser with thumb. Very easy and ergonomic to use. I use at work and home over ten years now.

1. Scroll wheel feels funky like going over a bad road with pot holes in it, not sure while they can use the same technology for the pointer for the wheel now that would be a smooth experience, Instructions are lacking, got it connected via bluetooth, but I an going to have to research how to get more than the basic scroll settings, I think their is a some software that I need to download yet, I'll have to hunt that down. Ball is pretty good but having trouble just using my thumb only to guide it. I had a "Marble" track ball before and it was much better but this one is not bad either. Feels kinda cheap as far as it's build given it's a Logitech I would have expected a more solid feel.

I purchased these in the past and loved them. I just purchased this now and do not like the silent clicking. The ball is also not as smooth and does not glide as well as it once did.

It works smoothly, though for me, my hands are not steady enough to place the cursor without error. I put some foam into the ball container but I will need more. Also, Logitech really needs to understand that their products are not so special that they require a dedicated USB slot ON THE COMPUTER ITSELF. I have a fairly high end computer but it only has two USB slots of the "old" rectangular type and a Type C. Anyone want to try doing anything slightly complex with only 1 USB 3 and 1 C port? The least they could do is make their sensor/plug-in/dongle work on a powered USB external extender. Also I do find the connection gets lost more easily than most, so if you finally get it working and put their device into a powered hub/extender and it needs to be re-paired, your up that famous creek. Incidentally, I also have their ERGO K 860 keyboard, which is also really nice except, because of their hokey connection set-up, it does not display in device manager under keyboards, and, once again, if it gets un-paired, there is a maddening sequence in which you are asked to "enter" a series of numbers on the keyboard, but there is NO PLACE TO DO THAT! You can't type in the window that shows up. They make some great products but they don't have to make them so difficult to install and connect.

You need to know this does not use a Unifying receiver if you're planning to integrate it with existing hardware. It uses Logitech Bolt (comes with usb dongle) or just connect directly via Bluetooth. I went with the direct Bluetooth connection and it's working flawlessly. It does not make clicky noises with the buttons. At first I didn't like the absence of that feedback, but I got used to it and there is still a physical feedback of the button detent. It is lighter than I am used to, but still sufficient.

For some reason this is not very precise. When I use it there is a bit of a delay

Color, textura, materiales

タイトル通り。あとは従来と変わりありません。mxキーボードと合わせて購入しました。 ゲーム目的でないので、マウスはもともと遅延とは無縁。キーボードはlogiboltにして遅延がかなり少なくなったと体感できます。 今の所接続不良はありません。 BTの接続で裏のランプが青くならないのは？？私だけでしょうか。ただBTでは接続しないので気にしません。

I'm a sucker for a trackball and this is right up there with the best. While not as robust as the original trackman, this is lightweight, functions as one would expect with great tactile rolling and button feedback and pairs with multiple devices and OS's with ease. Highly recommened, even if you've never used a trackball before! Worth its weight in gold.

It works perfectly fine. Not very practical for big hands. It works better on the palm with people that have small hands.
