SANWA (Japan Brand) Wired Ergonomic Trackball Mouse Silent Noiseless Optical Sensor Mice (600/800 / 1200/1600 Adjustable DPI 34mm trackball) Compatible with MacBook Laptop Windows Mac OS

Tiene un desplazamiento suave, pero la velocidad del puntero sigue necesitando ser reiniciada.

I have used trackball mice in the past but getting them at a good price, and finding one that just seems to fit naturally in my hand these days has been difficult. Sanwa has a history of making some of the best components for arcade machines in Japan, and to find a PC trackball mouse from the manufacture is quite exciting. It fits perfectly in my hand. It has reduced strain on my wrist. It took no effort to get used to it. It just feels natural. I highly recommend.

Brilliant near-silent buttons, soft matte feel to the palm rest and buttons - I actually prefer that it's wires and not bluetooth!

I've used Logitech's Trackman Wheel for decades. Finally wore out my 2nd one and they don't make that model anymore. Sanwa's Trackball is the closest thing I've found to it.Is it just as good? No. But it *is* good enough that I can still give it a 5 star rating.Got a good feel to it. Not festooned with extra buttons I don't want. The adjustable DPI is nice. Logitech had better software but being able to adjust the DPI on the Sanwa makes up for some of the difference.The only minor gripe is the pressure to make the right or left button make contact is higher that I'd like.OTOH, the wheel is *better* that on the Logitech. As it, it actually works all the time.Quite happy with it.---------- update 10-15-2024 -----The scroll function of the wheel works... except on some websites or programs it hardly works at all - moving in the wrong direction. Odd but it seems to be a problem on the other end.

This is pretty comprehensive. These are most of the things I wanted answers to before I bought this mouse.November 25, 2019: Read through to the end for the update.I've been using a Logitech Trackman Wheel (that's pretty much the wired version of the Logitech 570) for about 20 years. I've repaired it a few times for various problems. I love that thing.I just got my SANWA GMATB128BK a few hours ago. So far: I love it.The button on the top that lets you adjust the speed for the cursor is WONDERFUL! I turned my pointer acceleration all the way down because I can now just tap a button and adjust how fast the cursor moves in response to the speed I move the ball.I wasn't sure I was going to like the position of the speed adjustment button but it turns out that it's in a really good location. Being centered, there isn't really any chance you'll push it when you left- or right-click. But it's not so far out of the way that it takes any significant effort to push it.i am REALLY glad I opted for this mouse because it has four speeds. The slowest speed is perfect for the small movements you have to make when you're doing design work on a 3D model. The highest speed is just... Really fast. But it's SO easy and convenient to switch between them. I'm not sure how I've lived all my life without this feature. (For those who are easily confused: One blink is the slowest speed. Four is remarkably fast. The LED is not in a great spot but I can see it light up the bottom of my finger and count the blinks if I forget what speed I'm on. It's a more useful feature than you might initially expect it to be.)The ball rolls like silk. If I give a good shove it just keeps spinning.The buttons and scroll wheel are SILENT. (The buttons and wheel on my old Trackman clicked audibly. It never bothered me, really, until now. Silent is better.)I'm not sure if the shape is exactly perfect but it's slightly different compared to my old Trackman Wheel. It may be that I'm just used to the shape of my old mouse. It may be just a tiny bit short in the back end. Either way, the Trackman Wheel is a different shape and longer. It seems more comfortable to me. I'm sure I'll get used to how it feels pretty quickly.It seems a bit wider than the Trackman Wheel. It almost feels like a little bit of a stretch to get my thumb to the ball.The shape of the front of the mouse actually feels a LOT better than the shape of the Trackman Wheel.There is definitely something different about where the scroll-wheel is. The scroll-wheel on the old Trackman Wheel seems a little better positioned. It seems better positioned to click it with my middle finger than my index finger. But that feels pretty awkward, honestly. I can say that I really use the middle mouse button a lot in CAD work and in Cura (a slicer for 3D printing). I'm sure it will be fine. Again: I'm sure I'll get used to how it feels pretty quickly.The size of the mouse is going to feel different for different people, of course. I can only speak for how it fits my hand.Being a trackball there really aren't a lot of reasons you'd want it to be wireless and plenty of reasons you'd want it to have a USB cord. I was a little concerned about how long the cord would be. As it turns out, it's just slightly longer than the cord on my old Trackman Wheel. Good job, SANWA! Thanks for not cheaping out with a short cord like a lot of manufacturers do these days.The price is definitely right. Cheap, even. I paid the same amount for this that I paid for the Trackman Wheel. TWENTY YEARS AGO (When twenty-five (-ish) bucks was worth a lot more than it is today). I paid ten dollars MORE for my wife's Trackman Wheel than I did for this mouse.It works perfectly on Linux Mint 17.3. I expect it will work fine on any OS. It's, "just a mouse." And that's how the OS is going to see it. The speed switch isn't OS-dependent. It's part of the mouse hardware. The OS doesn't even know the button is there and it doesn't need to know it's there. YOU DON'T NEED TO INSTALL ANY SOFTWARE TO RUN THIS THING. It's JUST a mouse. The mouse driver built into the OS will just see this as any regular mouse. Only your arm will know the difference. (Your arm will thank you by not being in constant pain for a week if you spend too much time on your computer.)My first impressions are that this thing is just about perfect. If it breaks you can be sure I'll be updating this. I really don't expect it to break.PS: Don't listen to the people who are complaining about how any trackball mouse moves. My bet is that they probably have no idea how to adjust the speed of the mouse (even though a small child would figure it out in a couple of minutes) and aren't used to moving the cursor with their thumb instead of waving their hand all around the desk.So... Now it's November 25th of the same year... And, it's begun.When I turn my computer on in the morning sometimes I have to crawl under my desk and unplug the mouse and plug it back in again. No. It's not the computer. I've had half-a-dozen different mice connected to this computer and I've never had to do that. It's the mouse.Sometimes it will click just fine but the cursor won't move. One morning I sat here for a couple of minutes (dreading the trip into the terrifying land of dust bunnies and spiders developing their own civilization under my desk) watching the mouse wander randomly across my screen. I could click things, still, as the mouse went flying across them. It was, for a few minutes, an entertaining game. And far more entertaining than having to try to get past the border guards to the kingdom of the dust bunnies (they're brutal, you know). Happily, I completed my quest and the mouse worked again. Until the next morning. When, once again, I had to elude the guards on my quest to unplug and re-connect my new mouse.I will, of course, be requesting a warranty replacement. I'll certainly update this on how that process goes.18Jan2020 update:The replacement mouse is working fine. No troubles at all. It's still a great mouse and I love it. The ball doesn't spin quite so freely any more but it's not magical. Dust and oils from your hands gets in there and makes it sticky. Whatever. There is really no way to prevent that.The return/replacement process was a nightmare. That wasn't the seller's fault, though.I never got a message telling me how I was supposed to send the old mouse back to Amazon until a month later when they sent me a message telling me that if I didn't return it in the next week or two I was going to be charged more than I had originally paid for the thing. That certainly makes sense, right? Fortunately there was also a link to a shipping label so I printed it out and set it out to be picked up by the postal carrier... Oops... It's not a USPS label. It's a UPS label. And they don't pick up. The nearest place to take it was 30 minutes away from my home. Nice...So, off it goes. Everything's fine, right? Wrong. Three weeks later I got a message that said that my card HAD BEEN charged for the mouse. Not that it was going to be charged. That they had already charged me for the mouse I had already returned. I kinda got a bit cranky over that.I went to find the shipping label and get the tracking number from it. Checked with UPS's tracking, sure enough, it was delivered to Amazon two weeks earlier. Huh?So I spent 15 minutes trying to find the stupid, "contact us," link that they hide, got someone on the chat service and chewed them out. They got it straightened out and my card was never actually charged. Regardless... When you're having a look at your emails right before you head to bed and find that kind of thing it's not exactly fun.So, there it is. Great mouse once they replaced the first one. Does that mean everyone is going to get a bad one off the bat? Nope. I've bought a hell of a lot of computer hardware in my life. I've almost never gotten bad hardware. This is probably the third or forth time. It happens. That's fine. I'm very pleased with the mouse.
