MicroPack Wireless Trackball Mouse, 2023 New Upgrade Ergonomic Mouse with Wireless Vertical Rollerball Computer Mouse, 3 Adjustable DPI, Easy Thumb Control for PC, Laptop, Mac, Windows - Black

My logi mouse went crazy and needed a replacement, plus my hand hurt after long use, so I started looking for a vertical mouse. The Logi Lift is a natural candidate, but this cheaper alternative is quite intriguing, so I decided to give it a try before I buy the more expensive Logi. This one seems a keeper. Hand hold feel very comfortable.Initially, I feel my hand has to move a lot more to get the mouse move (for not so precise work), but after I adjusted the DPI setting, it seems more responsive now. Still feel more time to get used to, but no significant negative feeling. The click is very light and quiet, if that is what you looking for. I used it at home and somewhat prefer stronger click feedback. But again, I see he benefit of quiet operation as well.Don't know how long this will last. However, even the more expensive Logi will break eventually. So, my initial feeling of this product is very positive. Will update if things change.

I play a lot of World of Warships, sometimes for hours on end. A mouse takes up a lot of room to use. Not just sitting still of course, but all the area they need to cover compared to a trac-ball that stays stationary. No need for an additional pad, or worry about the edge of the pad or having to lift move drop and start again. This rests the hand in a comfortable position. Track-balls in general take time to get used to, but I think once you do, you will want nothing else and this is a top quality one for sure.

Ive been using this for months now. I think its helping a lot with my wrist but it keeps turning off and not turning back on. I've missed multiple calls at work because my mouse falls asleep and does not wake up until I flip the off/on button back and forth and by that time I lost the sale and lost money in my pocket. SO really this mouse might physically help your wrist, but it will cause you to lose money if you cant get your work done!!!UPDATE: The mouse is junk. I even tried to order a new one and within a WEEK, its sticking so bad. I have not eaten or used sticky hands before using this. I have been so careful to keep it clean and put away when not in use. It just has to go and I need to spend more money on good quality.

Purchased this mouse July 2023, it is now April 2025. Mouse has worked fine until about 2 months ago. The left-click button has begun double-clicking on its own, which is very frustrating when trying to drag and drop things. Other than that, this mouse has worked fine so far.

I absolutely hate touchpads and in most of the places where I use my laptop and even on several of my desktops, the real estate is such that using a traditional mouse is very difficult or impossible. I usually rely on trackballs. They all have had some drawbacks. I have a Logitec and a Microsoft in the standard horizontal configuration. First of all, horizontal is not very ergonomic. The natural position of your arm on the table it is to have the hand vertical. In addition, because of the design, your hand tends to push forward on these devices making them slide. On my large desktop computer, I actually have used double-faced tape to stick it to the desk because the sliding became so annoying with the Microsoft unit. This device is extremely ergonomic and natural feeling to use. There is no tendency to slide or move whatsoever. I have never used the "forward/back" buttons on any of my other trackballs so I don't miss their absence on this device. You can switch the sensitivity but the press of a button behind the thumb wheel. Very convenient. One thing that does take a little getting used to is what to do with your thumb when you're pressing the left mouse button. With a traditional horizontal trackball, you're pressing down toward the table so there is no tendency to move the cursor. With this device, when you press on either the left or right button what you're actually doing is "squeezing" the button towards the ball. The result is there can be a tendency for your thumb to move slightly on the ball and move the cursor. This gets a little easier to control with practice however there's also a very convenient ridge right above the trackball to rest your thumb on when you're pressing the buttons which makes it a little bit easier. Dragging and dropping is the only thing that is really kind of tricky. With a traditional mouse or trackball, since you are pressing down on the button, using the ball itself is an independent motion and easy to do. With this device because of the squeezing action, it's a little tricky to keep the left button pressed while you are manipulating the ball to drag something to a new location. Not that it can't be done. With little practice you can learn to press slightly downward on the button as opposed to the left which takes the pressure off the thumb and allows you to do the dragging motion. What would really be nice is a mechanism to turn the left mouse button into a sticky key but I haven't found any way to do that yet.I have seen reviewers downgrade the device because the ball becomes "sticky". As someone who has used various designs of trackballs for well over a decade, I can tell you this almost always results from either the ball itself or the supports inside the ball cavity becoming dirty. If you are using this in an environment where your hands are likely to be dirty or sticky or there is a lot of dust around, frequent cleaning is definitely going to be necessary as with any trackball. And if you have little ones using your computer, figure on cleaning the ball mechanism pretty much every time they get their hands on it.The price is very reasonable and if you are looking for a more ergonomic alternative to a traditional trackball, it's well giving this a try. I will probably be replacing the cursor control devices on all of my computers with this unit.UPDATEI'm afraid I have to downgrade my rating to 3 stars. I have been using these devices on two of muy laptops for 4 and 6 months respectively. To those reviewers who said the ball became "sticky," I know now what you mean. It is not so much sticky as rough. Originally both were smooth as silk but BOTH have now become extremely rough and jumpy, I have removed the balls and thoroughly cleaned the balls and sockets-no help. There is something with the tiny supports that hold the trackball. the ball itself seems fine but it feels like it is resting on sand. Actually hard to get the cursor in the right place because it is so jumpy. Since it happened on both of my samples and I have never had this happen with other brands, I have to assume there is a defect in the design or materials. I can no longer recommend this device.

BUT the ball moves if it's not level. I don't yet have a level surface for my input devices, but since I like this one I'll make it happen. If you let it tilt to the left a little bit the cursor will move when you take your thumb off the ball because the ball will move slightly. This can lead to mis-clicks. All of you using a proper desk or table should never have this issue. I compute from my couch with a big rounded armrest--and is why I had to quit using mice. I did have trouble getting it up to speed on one system to I swapped it to the other one where it works fine. If it weren't for this I'd buy a second one for the other system, but a new release of Mint should fix that, and it's up. I just haven't done the upgrade.

love the design. Works alot better on my wrist compared to the old track ball.
