I REALLY love this mouse in spite of one little downside & one VERY annoying one. The minor annoyance to me is easily overcome. So, I overlook it because the auto sleep mode actually makes sense to me.Ever since getting this new wireless mouse, its worked a heck of a lot better I I have only charged it a couple of times since buying it. One little point to make is that I use my PC A LOT & more of my mouse than the keyboard. So, you would think that the battery would run down faster with all the use I'm getting out of it.NOT A SNOWBALLS CHANCE IN HELL!This thing just keeps on working for weeks on end like a champ & I like using the Bluetooth option over the dongle that can be found fastened to the underside of the frame of the mouse. I like it because....1) … when the dongle is plugged in, it takes up another slot that I could later use for something else.2) … I have yet to see any power indicator if I use the dongle connectivity option so I would have no idea when to plug the unit in to charge it when not in use.The down side to the Bluetooth option... I can't just simply shut off my Bluetooth on my PC when switching my headphones over to my fire TV which also allows for Bluetooth headphones. The mouse will stop working obviously which is a problem because then, I have to go back to my old wireless mouse which does work on a USB dongle plug which I still have plugged in just in case but it has a lot of glitches & it doesn't always work as well to my satisfaction since its wearing out.Anyways, when it comes to the one very annoying downside that I have to live with as I constantly remind myself not to shut off the Bluetooth.Mind you, for the sake of context, I have my PC in my bedroom connected to a large screen TV that also serves my fire cube & all my different gaming systems because of my being a video game nut. I also have to have the PC connected to my TV since my eyesight has been getting poorer as I get older.So, the larger text on the big screen helps me to see better & the new mouse works like a champ! It has a built in battery which is nice unlike my old one which needed a new battery every couple of months or the mouse would glitch on me until I replaced the batter again but these days, it doesn't matter if I have an old or new battery in it. So, now its just used as a backup while this newer mouse just keeps a ticking better than a Timex watch ever did.Lastly, unlike my old remote mouse that would have the roller ball part pop out if I accidently dropped it on the floor, the ball on this one has stayed in when dropped. Its really held together nicely & for the sake of helping the Amazon AI on ticking off all the issues, yes, its comfortable & very accurate so no worries there.lastly, its totally worth the price if you are looking for a affordable wireless option.

I bought this Bluetooth mouse to replace a previous brand that lacked wireless functionality — and I’m so glad I did! No more chasing down that tiny dongle or worrying about forgetting it on the go. This mouse gives me the freedom and convenience I was looking for, without the premium price tag.🖱️ Smooth Setup, Custom Style:Setup was a breeze, and I love that I got to choose my trackball color — a fun touch that adds a bit of personality to my workspace. It’s also incredibly comfortable, making long hours at the computer so much easier.💪 Goodbye Wrist Pain:I used to suffer from constant wrist pain using a traditional mouse. Switching to this one has made a huge difference — the pain is completely gone! It might take a little getting used to at first, but once you adjust, the ergonomic design is a total game-changer.🔋 Modern Charging Made Simple:The fact that it charges via USB-C is the cherry on top. No more digging for specialty cables — just plug it in like any other modern device. Simple, smart, and efficient.✅ Final Verdict:This mouse is a comfortable, wireless, and budget-friendly alternative to the high-end brands — and it doesn’t sacrifice on features. Whether you're looking for better ergonomics, wireless freedom, or just a clean setup, this mouse checks all the boxes. Highly recommend!

June 22, 2025:I've been using the Logitech Trackman series since the 1990's, the M570 for the last 15 years, and decided to try something different and a little less expensive this time. Here are my initial thoughts after 2 weeks:Operation -Operation is smooth, precise, and just as good as the M570. I plugged the USB transceiver into my Windows 7 computer and it installed the driver and the mouse was working perfectly in minutes.Mechanical - Only time will tell how it holds up under normal use. The M570 buttons are it's weak point and usually start failing by not clicking or double clicking, but that usually takes years to happen. (BTW, the buttons are just micro-switches that are easily replaced for a few bucks if you have a soldering iron.)Ergonomics - It's big; slightly larger than the M570. I have a hand that is larger than most and feel like this trackball is almost too big. In all fairness, I'm sure that I'll become used to it, but after using an M570 for so long, the difference is definitely noticeable. The buttons feel "almost" the same as the M570 with the rear "right click" button being slightly less prominent. The scroll wheel detents are slightly smaller so if feels a little less "clicky", but overall, they all operate as they should.Size:Larger than LogitechSmoothness:Smooth as butter on a warm summer dayWhy did you pick this product vs others?:Price

Product is almost a copy of the Logitec track ball mouse except that this has a black coating on it that is exstreamly slippery? Not sure what coating it is but its just odd as my hand slides when resting on it. The mouse also goes to sleep when not used for a certain period which is not productive with the Mac when the screen is put into sleep mode. Best way around that is to click the left button once and wait for it to wake up before doing anything and sometimes its not a quick turnaround for it to wake up. Other than those two odd issues it functions well with the track ball. Consumers will just have to decide for themselves. Wonder if the buttons will last longer than the logitec track ball? Time will tell. I gave it the four stars because of the two odd things about it.
