Logitech M575 Ergonomic Wireless Trackball USB Mouse, Black (910-005869)

I have been using Logitech Trackball mice for many years — ever since I developed RSS repetitive stress syndrome in my dominant hand. Most inconvenient and painful! Logitech trackball to the rescue! Trackball use cannot cure RSS, but it might do wonders to ease your discomfort/pain as it did (and still does) for me.

Nowadays, trackball mice are getting difficult to find as user needs and interests evolve. I kept searching for a NEW (not refurbished) Logitech trackball and finally found this model. There are very few changes between this trackball and my previous similar Logitech models; those micro-differences don’t matter to me.

All I care about is that my new Trackball is working perfectly for my needs. Scrolling has always been the primary indicator that my trackball was wearing out. My new Trackball’s scrolling is reliable and smooth.

If you’re still old school in some of your tech habits as I am, this Logitech wireless trackball may be your best replacement or a good introduction to using a trackball mouse. Wireless, no cords to tangle (or find a spare port to plug into is a big plus!

I anticipate I’ll get another 10 years of trackball use out of this new model. And when I’m ready to move beyond this tech level, I’ll start my new device search with Logitech.

I bought this item to replace an old Logitec trackball that I’d had for years and which was getting unreliable. The new one has better hand grip than the old model and works beautifully, allowing precise and accurate movement. Highly recommend. Got delivery in just a few days and item was very well packaged. I am very pleased with my purchase.

Works well. Easy to use.

So I’ve been using Logitech thumb-based trackballs since they were rectangular and connected with a DE-9 serial connection. I swear by them and have converted many others.

The advantages are clear: you don’t need huge swaths of desk space to move them around, you can remove your thumb from the ball so you don’t inadvertently move the cursor when you click, and the interface is extremely intuitive and easy to use. The biggest disadvantage is that they are solely right-handed — my two lefty kids can’t use them. The kids also say they’re not great for gaming so that might be a factor; my youngest uses some specialty mouse designed specifically for gaming.

As for this particular model, it’s not terribly different from the previous M570. Note: in the pictures, the new M575 has the more silver ball; the one with the more blue ball is an M570.

The forward/backward buttons (between the left mouse button and the trackball) are less prominent on the newer model and include indentations that appear to be simple circles. I’m guessing that the circles are meant to give your finger a reference point to be able to click without looking but I find them more annoying than useful (they feel like there’s a piece of dirt or something stuck to them) and the prominent buttons of the M570 were easier to feel, as well as being less susceptible to accidental clicks.

The palmrest part of new M575 as some subtle ribbing, probably meant to keep your hand from slipping from side to side but it’s honestly just another annoyance. Not enough to prevent me from using it but given the choice, I would prefer it without.

The activity light/battery warning light has moved from just behind the forward/back buttons to the middle behind the main mouse buttons. Not a problem at all, just different. I will note that the light on the M570 can be seen even when your hand is on the trackball whereas this one is covered up by your hand.

The trackball itself is fine; I think I like the old blue color better but there doesn’t seem to be any other difference.

The bottom of the trackball is not functionally different from the old version and it’s good to see that the slot is still there in the battery compartment to hold the receiver. The power switch is a little smaller and harder to access but still perfectly functional. There is a new button that appears to switch the trackball from using the receiver to using bluetooth — a handy feature if you want to use it with something like a tablet, I suppose. (I’ve not tried it via bluetooth.)

If you’re thinking about upgrading from an older M570, you’ll feel right at home, for the most part, but I don’t think there’s any compelling reason to rush right out and get one. I bought a new one because the scroll wheel on my old one stopped working reliably. Had it not, I’d still be using the M570. (Note: I still use an M570 in my office, as does my wife.)

If you’re new to this style of trackball, imagine laying your hand on a gently curved rest and moving your thumb around. It’s comfortable and less stressful than a traditional mouse and it requires a lot less free desk space. It doesn’t need any particular type of surface; I’ve used it with it on my leg, on the bus seat next to me, and on my bed.

It’s not the cheapest device in the world but if you’re hesitant to spend $50 on a trackball, you’re probably not a heavy or serious user. Gamers will probably look elsewhere and possibly even pay more; casual users will be looking for something in the $15-25 range. I’m in front of a computer 8-12 hours per day and I don’t mind spending a bit on something to make that experience more efficient and more comfortable. If you want to try a trackball without spending as much, there are some decent knock-offs on Amazon that should be fine. But if you don’t mind investing in something like this, it’s well worth it.

This is the second one I bought as my wife “stoled” my other one. Had the first one foe years. Great quality, great fit, easy to connect wireless and easy to get used to.
