Review on 🖱️ Enhanced Ergonomic Trackball Mouse: SANWA 2.4G Wireless Optical Vertical Rollerball Mice with Silent Buttons, 34mm Trackball, Adjustable DPI, Compatible with MacBook, Laptop, PC, Windows, macOS by John Hall

This is pretty comprehensive information. These are the most questions I wanted answered before purchasing this mouse. November 25, 2019: Read to the end to learn more about the update. I've been using the Logitech Trackman Wheel (pretty much the wired version of the Logitech 570) for about 20 years. Repaired several times for various reasons. i like this thing A few hours ago I received my SANWA GMATB128BK. So far: I like it. The button at the top that allows you to adjust the cursor speed is AWESOME! I've completely reduced mouse pointer acceleration because now I can just press a button and adjust the mouse pointer speed to match the speed at which I'm moving the ball. I wasn't sure I would like the position of the speed controller. button, but it turns out it's in a very good place. Because it's centered, there's no chance you'll click on it when you left or right click. But it's not that far, it takes some significant effort to push it forward. I'm REALLY glad I chose this mouse because it has four speeds. The slowest speed is ideal for the small movements you need to make when designing a 3D model. Only the highest speed. Really fast. But switching between them is SO easy and convenient. I'm not sure how I've lived my entire life without this feature. (For those who are easily confused, one blink is the slowest speed. Four is surprisingly fast. The LED isn't in the best spot, but I can see it light up on my fingertip and count the blinks if I forget which one Speed (This is a more useful feature than you might initially expect.) The ball rolls like silk. If I press hard, it just keeps spinning. The buttons and scroll wheel are MUTE. (The buttons and wheel on my old Trackman clicked with an audible sound. In fact, it's never bothered me until now. No sound is better.) I'm not sure the shape is exactly perfect, but it's a little different from my old Trackman bike. Maybe I'm just used to the shape of my old mouse. It can only be a little short at the back. In any case, the Trackman Wheel has a different shape and is longer. It seems more convenient to me. I'm sure I'll get used to how it feels pretty quickly. It appears to be slightly wider than the Trackman Wheel. It seems that you have to stretch a little to touch the ball with your thumb. The shape of the front of the mouse actually seems MUCH better than the shape of the Trackman wheel. It's definitely something different where the scroll wheel is located. is. The scroll wheel on the old Trackman Wheel seems to be placed a bit better. It seems better to click on it with your middle finger than your index finger. But it looks pretty awkward to be honest. I can say that I use the middle mouse button a lot in CAD and Cura (3D print slicer). I'm sure everything will be fine. I'm sure I'll get used to the feeling pretty quickly. Of course, the mouse size is different for different people. I can only speak about how it is in my hands. Being a trackball, there really aren't many reasons you would want it to be wireless and many reasons you would want it to be USB corded. I was a little worried about how long the cable would be. It turns out it's a bit longer than the cable on my old Trackman bike. Well done SANWA! Thank you for not skimping on a short cable like many manufacturers do these days. The price is definitely right. Cheap even. I paid the same amount for it as for the Trackman Wheel. TWENTY YEARS AGO (when twenty-five dollars was worth a lot more than it is today). I paid ten dollars more for my wife's Trackman Wheel than she did for this mouse. It works fine on Linux Mint 17.3. I assume it will work fine on any operating system. It's "just a mouse". And this is how the operating system will see it. The speed switch is operating system independent. This is part of the mouse hardware. The operating system doesn't even know the button exists, and doesn't need to know it exists. YOU DON'T NEED TO INSTALL ANY SOFTWARE TO RUN THIS THING. It's ONLY a mouse. The mouse driver built into the operating system sees this as a normal mouse. Only your hand will tell the difference. (Your hand will thank you for not being in constant pain for a week if you spend too much time on the computer.) My first impression is that the thing is almost perfect. If it breaks, you can rest assured that I will update it. I really don't expect it to break. PS: Don't listen to people complaining about how a trackball mouse moves. I bet they probably have no idea how to adjust mouse speed (although a small kid can figure it out in a few minutes) and aren't used to moving the cursor with their thumb instead of waving their hand. around the table. Now November 25th of this year. And it started. Sometimes when I turn on my computer in the morning I have to crawl under my desk and unplug and plug my mouse back in. no This is not a computer. I had half a dozen different mice hooked up to this computer and never had to do it. That's a mouse. Sometimes it clicks normally but the cursor doesn't move. I sat here for a few minutes one morning (afraid to travel to the horrid land of dusty rabbits and spiders developing their own civilization under my desk) and watched a mouse randomly wander across my screen. I could still click on things when the mouse hovers over them. For a few minutes it was an entertaining game. And it's a lot more interesting than trying to get past the border guards and into the kingdom of dust bunnies (they're cruel, you know). Luckily I completed my search and the mouse started working again. Until the next morning. When I had to escape the guards again by trying to disconnect and reconnect my new mouse. Of course I will ask for a replacement under warranty. I'll be sure to let you know how the process goes. Update 01/18/2020: The replacement mouse works perfectly. No problem. It's still a great mouse and I love it. The ball no longer spins as freely, but that's not magic. Dust and oils from your hands get there and make it sticky. However. There's really no way to prevent this. The return/exchange process was a nightmare. However, this was not the seller's fault. I never got any message on how to send the old mouse back to Revain until a month later when they messaged me saying I should have paid more than I paid if I didn't have it in Should have sent this item back in the next week or two in the first place. It sure makes sense, doesn't it? Luckily it also included a link to a shipping label, so I printed it out and gave it to the postman. Oops. This is not a USPS label. This is the UPS label. And they don't get caught. The closest place to get one was 30 minutes from my house. Good. So let's go. It's all right, isn't it? Not correct. Three weeks later, I received a message that my card was charged for the mouse. Not that they would accuse him. That they have already taken money from me for the mouse, which I have already returned. I got a little angry about that. I looked for the shipping label and received a tracking number. Checked with UPS tracking, in fact it was delivered to Revain two weeks early. BUT? So I spent 15 minutes trying to find the stupid "Contact Us" link they are hiding, found someone in chat and chewed them up. They fixed it and my card was never actually swiped. In spite of. Going through your email right before bed and finding things like this isn't exactly fun. So here it is. Great mouse after they replaced the first one. Does that mean everyone gets a bad report card right off the bat? nope I've bought a heck of a lot of computer hardware in my life. I almost never had bad equipment. This is probably the third or fourth time. It happens. It is in order. I am very happy with the mouse.
