ELECOMTrackball Mouse 2.4GHz Wireless Thumb Control Sculpted Ergonomic Design 6-Button Function, Smooth Tracking, Windows11, macOS (M-XT3DRBK)

For too long the only real option for a good thumb track ball mouse has been available from logitech and even they reduced their range over time, leaving just the wireless m570 as the only one. What is unfortunate is they also cheaped out on some of the components used too (probably due to lack of competition) which often causes them to develop a fault with the buttons/switches (often registering double clicks or not at all). It seems like a very common problem and more than just annoying! It makes them unusable! This is what happened to mine of course and repairing/fixing the issue meant having to replace the switches (too much hassle) or purchasing another, which again was likely to get the same fault after an unacceptable amount of time considering the price.For a long time I searched for alternatives but many seemed to suffer from poor design and other annoyances/lack of features. Finally I stumbled across this Elecom EX-G M-XT3DRBK (Careful of the stupid naming scheme, there are a few variants!) so order it, but thinking again, its likely it would not be what I had hoped. Thankfully I was totally wrong, its been excellent so far. Not only is it a good replacement from the m570, its better in just about every way. It has more buttons and functions and has not developed any fault even after continuous abuse. It also has a nicer feel than the m570, especially the finish quality and shape as well as the button clicks (specifically the back/forward). It makes the m570 feel cheap in comparison IMO.It has 3 buttons + scroller + scroller tilt clicks left/right/center as well as the normally back forward buttons, it also has a high and low speed switch (I use mostly high). All the functions work using the default plug and play drivers, except for 1 of the 3 main buttons, but using Elecoms own driver/software can over come this and also has the added benefit of assigning anything to any of the above functions, including gesture options! The only thing is misses is the precision option, but that can be selected in windows mouse option and you are good to go. Just search for ELECOM Mouse Assistant (global) to find the download.The only slight annoyance (cant call it a fault) I could find was the smoothness when new, but this seems to have improved with use and now feels much smoother than the m570 ever did. The name of the product is also a bit stupid, Elecom really need to sort out their naming scheme as its just confusing, still it does not take much away from the product itself, which I would not hesitate to highly recommend to any looking for good thumb tracker ball.I believe this to be the best thumb tracker ball currently available on the market.

I love thumb controlled trackballs, but there just aren't many options available these days except for the Logitech M570, which has all the usual build-quality issues I've come to expect from Logitech's increasingly shoddy devices, namely mouse buttons that become increasingly unreliable after only a few months of use.After chancing upon a recommendation to try Elecom I did so, and I haven't looked back; it's an excellent thumb-trackball with only a few minor niggles, which I'll try to summarise:Pros:1. Excellent design in terms of comfort, especially for someone with larger hands (but it should be comfortable for all).2. Flywheel scrolling with tilt for limited horizontal scrolling.3. Very good build quality with excellent mouse button switches.4. Solid battery life, with options to adjust wireless signal strength and tracking sensitivity for either faster speed or longer battery life.5. High DPI setting has very high precision with a bit of a practice; not sure if I'd use it for gaming, but any work requiring precision will benefit.Cons:1. Takes a little getting used-to; you might find yourself accidentally right-click a lot until you get used to it.2. Stock ball requires a lot of wear-in before it feels smooth, this may cause it to feel a grind-y for the first week or two of use. If you have a spare Logitech M570 ball not only does it fit, it feels a lot smoother straight away.3. Elecom software is incompatible with newer versions of macOS, meaning limited control of some functions, notably the extra buttons and the horizontal scrolling speed (though Mac users may find that holding Shift while scrolling is easier anyway).Specifically comparing to the Logitech M570:1. Far superior build quality, more comfortable fit.2. Battery life is shorter, though you should still get at least a month on low wireless signal and low DPI for a single AA battery.3. Requires more frequent cleaning of the ball area (every 1-2 days compared to every 3-4 days, both with heavy use), but cleaning is very easy.So to conclude, the main things that really let this mouse down are the stock ball, and the broken macOS software; if these were addressed this mouse would easily be a 5 star product, and regardless of these minor issues it's vastly superior to the Logitech offerings (including their new £90 rip-off). If I could I'd have rated this a 4.5, but I can't justify rounding up when there is room to improve.

This trackball mouse has been a lifesaver for my wrist pain! Switching to this design has drastically reduced the strain I used to feel after long hours of work. The thumb-operated ball makes scrolling and navigating so easy and precise—it’s incredibly intuitive once you get used to it.The ergonomic design is comfortable to hold, and the customizable buttons are a nice bonus for streamlining tasks. It’s also great for limited desk space since you don’t need to move the mouse around.If you’re dealing with wrist discomfort or just want a more efficient way to navigate, this trackball mouse is a game-changer. Highly recommend it for anyone looking for comfort and functionality in their setup!

What a dreadful piece of tech. The trackball cannot be used precisely over small distances no matter what mode it's in - the motion is jerky and hesitant. The buttons also have very weak action so click with just the weight of your finger. Finally the toilet ball is in the wrong place and requires the index fiber to be lifted and moved sideways to make it work. Sent back within minutes of arriving

My last one (same mouse) only lasted about 18 months, if that. They aren't the best quality plastic to be honest and could do with a better grade of plastic.It seems to be getting harder to obtain wireless thumbwheel mice for some reason, so choice is rather limited now.Logitech (my other source) are getting VERY POOR in build quality and the last supplied was broken on delivery!At least this one worked out of the box!
