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

Had a little wrist discomfort - and after some testing - I decided that I needed a variety of hand positions to reduce the discomfort. I needed a high-resolution track ball and one that turned my hand quite far. Enter this device: It is easy to use. Has variable resolutions and a few buttons - I don't need a dozen programmable buttons. So far so good. It has made using the trackball much more comfortable. I would like the option to tilt the tackball still further - and its ok for small medium hands - but I would like it slightly larger. Or expandable! The Elecom served me well. This is the evolution of it. Top tip: I installed Mac Mouse - a programme for adapting any mouse. Cheap and effective, it added some customisable features that make this cheap trackball as flexible as many much more expensive options.

Very poor build quality. Lasted less than three months of regular use. Mouse ball now slipping and movement not being picked up. Never owned a trackball that failed so quickly. Avoid.

It's works ok but does have a 'cheap' feel to it.

I've been on the lookout for a trackball mouse with the sideways ergonomic design for a while now. The thumb trackball style has helped my carpal tunnel out a great deal, but laying my hand out flat to use them still takes a toll over long periods of time. So when I found this I had to give it a shot. It was worth it! As with any trackball mouse, I found it effective to take a little small machine oil on a cotton swab, go over the bearings the ball rolls on with the swab, then wipe up the excess with the dry end of the swab. It helps a great deal with ball movement. The dpi settings are a little extreme. Software to customize a sensitivity in between the max and middle settings would be nice, but once you get used to the max setting, it's pretty easy to work with. There's no real bells or whistles when it comes to features on this mouse, lack back keys for websites, but I've found I rarely use those anyway. But it is something to keep in mind. As is the fact that you can adjust cursor speed in Windows settings to make up for lacking more dpi differences using the mouse button. It would just be nice to have more options to switch on the fly. Overall a great mouse. My complaints are incredibly minor and certainly not worth docking points for considering the reasonable price.

It's pretty bulky and large for me, so it might be for larger hands. But the track ball keeps getting stuck to my thumb when I let go to type or something, moving the cursor. The ball is also very light and offers very little resistance, making it hard to select at times. There was also a tab to pull out the USB that bend the cover out of shape at the clasp.

Clicking works great. The price was reasonable but the base always move when using it. Seems as if the bottom grips are not sticky enough making it uncomfortable after a period of time. I had to brace it to my laptop so that it would not move while using it. (Frustrating) Would have given 5 stars if this was corrected!

Feels cheaper than a Logitech and calibration seemed off. Kept. It but went back to using my old ergo.

Ah, the ergonomic mouse that promised comfort but delivered nothing but frustration. If only I could give it negative stars, I would. This piece of "technology" is a masterclass in disappointment. At first glance, it looks like it could be the ergonomic mouse of your dreams. It fits your hand perfectly, and the sleek design gives the impression that it means business. But don't be fooled by appearances, for this mouse is a wolf in sheep's clothing and I'm definitely not on Team Jacob. The first sign that something is terribly amiss is its complete inability to respond. It's as if it takes pleasure in ignoring your every command. You move the cursor, and it just stares back at you, mocking your futile attempts to get work done. Oh, but don't worry, it's not entirely heartless. It occasionally decides to grace you with a response, but only after a series of desperate beatings on your desk that make you question your sanity and the state of your mouse. Yes, you read that correctly – this ergonomic marvel requires physical abuse to function properly. It's like it's in a toxic relationship with your desk and needs a good thrashing to rekindle its love for work. If I could return it after giving it a few rounds of office-spacing with a baseball bat, I'd send it off in a fiery blaze of glory just to make a point to all the other inferior mice out there. It's a sadistic game of cat and mouse, where you're the mouse and the mouse is the cat, reveling in your suffering. You find yourself questioning every life decision that led you to this point. Why did you think an ergonomic mouse would bring you comfort when it only brings frustration? Why did you trust the sleek exterior when the inner workings are a hot mess of dysfunctionality? In conclusion, this ergonomic mouse is the ultimate betrayal of form over function. It's a tantalizing illusion that lures you in with promises of comfort and style, only to slap you in the face with its incompetence. If you have any self-respect, avoid this mouse like the plague and save yourself from the endless cycle of desk beatings and frustration.
