ELECOM Bitra Small Travel Trackball Mouse with Case, Bluetooth Wireless, Thumb Control, Silent Mouse Click, Ergonomic Design, 5 Programmable Buttons

Purchased this unit as a travel version of my favorite desktop mouse, the Logitech M570...At first the price threw me a bit. But I figured with Amazon, I could always return it if I wasn’t satisfied...What I was looking for was a mini-version that would fit more conveniently in a small bag with a laptop or tablet.First of all the build quality is AMAZING!!! It is so far Superior to the Logitech, or the old Microsoft mouse I learned on, it’s not even funny! It is actually a Japanese designed product (although it’s made in China like everything else these days…) when I first opened it and saw how small it was I was extremely happy that it will be very packable, although I was also worried that it might not fit the hand very well- the ball is so much smaller than on the Logitech. But the ergonomics are absolutely fantastic!!! The keys are silent- no ”clacking”, and the track ball is so smooth there is no other comparison! Absolutely seamless operation with MacBook Air and iPad Pro… (on the IPad it worked immediately! The only issue I had was needing to download a driver-only needed to customize keys for the laptop- challenging until I used the name printed on the mouse, “Bitra”, “Elecom” can also be searched as it is apparently the company that is handling US marketing. Also the direction of the scroll-wheel is opposite out of the box from the one I learned on, but finding the “Natural” scrolling direction toggle on Apple products and turning that off immediately restored it to “the right way“!) Comes with an extremely well-made case, which I replaced as it was too large for putting in a small bag- but it would make a great storage or shipping case. So satisfied- I seriously don’t think I will ever use the larger version of this mouse ever again as long as this one is available!!! Worth every penny! If you’re like me and can’t see moving your hand around on a desktop like an idiot and Have gotten accustomed to this style of mouse don’t hesitate to purchase!!!👍😁

I needed a compact mouse that I can use in settings where there is no flat surface. When my laptop is propped up on a cable lacing bracket and I'm trying to troubleshoot an equipment issue, running a regular mouse on my pant leg gets old fast!This trackball mouse is just the ticket! Compact enough to fit easily in an already overcrowded tool bag, and easy to use without needing space to push the physical mouse around.It is much too small for use at a regular desk and my hand would cramp up very rapidly if I tried to do so, but that's not what I needed and it fits my use case perfectly!

I've taken to using a trackball a few months ago. Unfortunately, most, if not all of them, are very big. Too big for me, but it still works. I just wish I could find a smaller one (I've always used a small mouse, my last one was the Logitech MX Anywhere 2S).But that also means traveling with my current mouse (Logitech MX Ergo) is out of the question - it's big and heavy. Enter this little mouse.I just came back from a 2-months trip oversees where I used it exclusively, on a Windows 11 laptop, so I feel like I can review it now.+ Size! It's very small and very light. Easy to pack in any bag.+ Size! Again! I love that I was able to use it easily in the plane (in Economy) by just putting it on my lap.+ Connecting it to my laptop was easy.+ It works. Never had a problem.- The main issue is the trackball. It's not tight so it always move around a little. Maybe just a millimeter in every direction, but that's enough to impact accuracy and comfort, and to make the whole thing feel flimsy. This is my main issue.- The software. It may be good, or it may not. I don't know. It's in Japanese. I was able to customize the important stuff like pointer speed and a couple buttons, but I didn't dare go farther than that.Overall I really like this mouse and I'm keeping it, but I'll use it exclusively when travelling. Honestly, were it a little less flimsy, were the ball better set, and the software not in Japanese, I would have considered using it as my daily driver.

I'm a writer and spend much of my time on the road, out of touch with wifi, with a small tough book. Since I'm often writing & editing text at the smallest size font I can read on an 11-inch screen, I seriously hate the imprecision of the touch pad when trying to correct or move words. Room for a traditional mouse and mouse pad is not always available, but there's almost always a few square inches for this tiny mouse. (It can also be used in the pocket of your cargo shorts--just get used to the cursor jumping randomly around while you work.) I admit getting used to its small size required practice, but after a couple of years with my Brita, every other mouse feels clumsy and bloated. (NOTE: if you're going to be working out of doors, invest in a couple of replacement balls. You'd think red would be easy to spot in the wild, but in brush or tall grass it might as well be invisible.)

I bought this to use on tray tables while travelling in airliners where a mouse just doesn't work. I bought it for it's compact size, but the ball does not work well with the rollers. It constantly feels like the ball wants to come out of it's slot and it is very jerky. Even when putting pressure on the ball and rolling it in a circle you can feel the ball clicking in certain spots against the roller. As soon as you roll left it will come off the roller. Since I did not travel a lot after I bought this, I missed the return window. I see other reviews reporting the same issue, so I feel this is a design issue more than my particular unit. As you can see from my history I don't tend to post reviews, but this is truly an annoying product to use.
