Before going any further, let me stop and just say that I love this mouse. I have only had it a couple of days, and it is about as quirky as I am, but this mouse is really and trully everything I had hoped it would be. First, keep looking back at the price, which is amazingly affordable. Second, take a look around and the nearest similar device is a bulky version with a finger loop hole and basically everything to signal that it is for videogaming and not for the office. By contrast, this is like the classiest possible way to control your laptop during a presentation. If you had this, connected to a Macbook, controlling Powerpoint, people would assume it is some hot new tech they never heard of, rather than an actual obscure company with an idea that is bold and forward-thinking. That is if they even notice it, being so compact and discreet.
For anyone with limited mobility, this could be a really enabling device on a whole other level. The quiriest detail is also it's coolest feature once you master it, and that is the variable speed control beside the "on" switch. I never knew there would be such benefit to changing my mouse speed conveniently. This will be the key to enabling maximum mobility with this mouse.
There is one small drawback. I have medium-sized hands, so there is one motion that requires two hands, which is to move from side to side. You have to push down the scroll wheel and then roll the ball. That is the only feature I found here that requires two hands, excluding the moves that require that I hit shift on the keyboard before a mouse move.
However, if you are planning to work with this thing up to an hour strait, then you should anticipate switching hands or fingers to keep from getting a cramp. When I do switch hands and fingers, I am able to manage and not cause that type of cramping. Doing this also helps you to find the most relaxed sort of default ways to hold this. One way is if you slide your hand back, so that your first and second fingers are only at the very edge of each trigger button, then that promotes a hand position that is curled at an angle very close to the natural resting postion of your hand.
One final considerataion is that your success with this mouse will be linked to the task you most hope it will benefit. I got this almost entirely for graphic design, because the mousepad on my Macbook is not working ideally for my workflow, and the stylus-type pads are for drawing more than for designing. With most devices, the challenge is threefold. First, it is very easy to summon the left click on the Macbook trackpad, to the extent that it is so annoying and constantly in my way that I forget it's also a quick access to certain features. With this mouse, I am suddly actually using that left click and noticing it's options and benefits. Secondly, when I pull my finger off the Macbook trackpad, my cursor position is subject to a slight jump. That is a problem in precision graphics, and even the Wacom tablet or IPad with the Apple Pencil are not safe from this hiccup without a fair amount of finesse. This mouse solves that problem the second you get your ideal mouse speed calibrated, and get oriented to the device. The weight of the ball means the cursor absolutely only wiggles when you touch the trackball. This is the precision I needed. I can get used to the muscle memory of pressing the trackball to make it zoom in/out, and the two handed side-to-side movement is not too bad once I got in the habit of switching hands.
Why would you want to switch hands, you ask? Well, welcome to your new reality, because you don't have to be ambidextrous to use this mouse with either hand. That is another reason I feel this would be a really great and affordable solution for enabling people who may have limited mobility.
If you don't end up liking this mouse, it could only be because of a very limited number of reasons. Maybe you want to use this for many hours a day without changing up your grip or which hand you use, then this may not be the most comfortable mouse, unless you learn how to master that looser grip that I explained earlier. Another of the limited reasons you might not like this may be because of the size. This is probably most ideal for small-ish hands and least ideal for really large hands. My average-sized hands are maybe a small bit larger than what is ideal for this. Really, the bottom line is that if you are a person who wants to hold your mouse in your hand, not working it on the desktop, then I am convinced that this is the model to get, especially if you want it to be discreet. But that is why this seems like such an ideal mouse for giving a presentation, because it is nice and small in your hand and not like the handle-bar look it would have if it was the most ideal comfort for a large hand.
Some reviewers commented on this mouse, feeling that it was too light and not sturdy. Well, think of this as a mouse, because this is a...well, a mouse. It is equal in durability to the average mouse you have seen. This is not a piece of sporting equipment like a Wii controller that offers a rubber cover because it expects betting mistakenly tossed. Please do not toss this mouse. This is a tool that is sleek and designed for a professional who wants to whip their cursor around their monitor screen with an impressive sense of command and agility.
This is my ultimate mouse. Oh yeah, and the button to calibrate the speed is what you hold down to get the mouse to sync with your other gear. This can confuse you when you return to your Bluetooth menu on your laptop and click the old icon, which takes you nowhere. Again, hold down that calibration button beside the power switch on this mouse, and it will pop up in your menu as a new Bluetooth option.
There are so many amazingly well-thought-out features in this device. A feature that I really love and did not expect, is that I can control my music on iTunes or Spotify in the background, while I am designing on Affinity software, without having to summon the player window to appear in front of my graphic window. The circular play controls function independently of which app window is in front.
I mean...wow...really and truly, this thing checks every box I could have hoped for. We should be grateful they did not make this thing heavy for no reason, or three times this cost for no reason. This is simply a great product for a great price. I am thrilled with this purchase! Put the batteries in it and the weight is perfect!
- 3 DPI Settings with the touch of a dedicated button. With this mouse, combined with regular mouse speed settings, I was able to use this to play competitive FPS games! That's accuracy if you ask me. Since you're using just your thumb, there is slightly less control than a conventional mouse, but the hardware itself is incredibly precise. Keeping it clean, the track ball is INCREDIBLY SMOOTH. So accurate I turn off windows pointer precision!
- 10 Programmable buttons. Downloading their software allows you to map any keyboard or mouse input to any of the 10 buttons on the mouse, as well as macros! The software is in Japanese I believe but after installing you can switch it to English in the bottom left corner. Google the mouse name and "software" to find it on their site.
- Great battery life. I use lithium rechargeable batteries in this mouse and still haven't had to replace them in what might be thousands of hours of use? I don't think they were fully charged to begin with.
- Mouse connects instantly when turning it on and off, and pairing is as simple as possible.
- The software is better than the software LG provides for their mice, and I just bought a high end mouse from them. It's more in-depth and easier to use. Maybe I should have sought a second mouse from this manufacturer.
- Great ergonomics and comfort. This allows me to rest my arm in any position while using it, or freely move it around as I please. My hand is on the larger, skinnier side, and it still fits very well. As a person preference, I would prefer a larger/bulkier size with 100% of handheld devices I've ever used, and this device is no exception. However, my hand has never actually been uncomfortable using it yet, so maybe the convenience of it's smaller size is outweighing my regular personal preference. I could always find a way to make it a little bulkier.
- Range/connection strength stays at 100% while devices are in viewable distance. I have yet ever be out of range of a device while in use.
- Compatible with phone/pc/mac, I couldn't imagine many if any incompatibilities? Probably works on my Xbox too, I haven't tried.
- Durable! (With a side note) I have dropped this 20+ times, on hard floors (tile, wood) and imagined it would have broken, as it feels extremely light in the hand, but it is incredibly sturdy! Not a single sign of damage or abuse even being carried/jumbled around in bags of equipment. The side note is, you have to watch where the track ball goes when you drop it as it is removeable. It's not hard to see with it's red color! This is to allow the smooth movement and removal for cleaning. You can hold the mouse upside-down and shake it, and it won't come out, so it's as secure as it needs to be.
Honestly, if these guys could make an ELECOM Relacon Xbox/PC Bluetooth Controller, I would buy it in a heartbeat. I've blown through many JUNK Razer products, and even tend to destroy the OG Xbox controllers. Expensive Corsair Mice have let me down as well.
Top reviews from other countries
I haven't had any problems with the ball being loose. I've dropped it a large number of times (I'm clumsy) and the ball falls out probably half of the time. I can tilt it to any angle and the ball doesn't fall out, even if it's upside down and I'm shaking the device but not touching the ball. Hopefully that was a manufacturing problem that they've fixed and so others won't have the same issue reported in other reviews.
I like that it's possible to configure the buttons further, but don't love that it means I need to keep the software running. Machine-specicic software complicates using it on my work computer and also means I'd need to set it up each time I switch devices. I understand why they've chosen this route, but I'd definitely pay more for a device that stores its own programming. This means I do use the default settings where, for the most part, the only ones that regularly bother me are the left/right media buttons.
However, my main issue is that the receiver started to act up (even when the trackball is off) within 6 months of purchase. Unfortunately, I belatedly learned that it's not possible to just replace the receiver. That's really disappointing when the expensive part - the trackball device itself - is still working just fine! I like this device enough that I've now bought the bluetooth version (through the US since it's not on the Canadian site), but I resent that I had to buy it twice.
Lo primero no es un trackball "primario"... vamos que esta pensado como complemento a tu trackball-raton habitual. Tengo varios ratones de la marca elecom, y casi todos tienen problemas de fricción estática (cuesta mover la bola una vez que esta parada). Este caso desde el primer día esta funcionando muy bien. En los elecom "grandes" he tenido que cambiar las bolas... con la consiguiente perdida de garantía.
Usos:
Suelo dar charlas y hacer presentaciones y para este cometido es un magnificco complemento del puntero laser. Te permite pasar diapositivas, hacer zoom, señalar en pantalla, es ideal para este uso.
Se puede conectar con el ipad, por lo que te permite usarlo tambien como señalador. También se puede conectar con dispositivo android tipo tv box.
He probado a usarlo como dispositivio secundario... y tambien es muy util. Cuando me duele la muñeca derecha, cojo el trackball en la izquierda y lo uso para mover zoom y pasar adelante y atras. Te libera de mucho estress al quitar la rueda del ratón principal.
Otro uso intensivo que le doy es para pasar páginas del lector de libros (onyx boox note), si estás preparando oposiciones o similar sabras de lo que estoy hablando.
Conectividad:
La conexión es via bluetooth, hay otro modelo similar con una pastilla RF. Si lo vas a usar con ipad, android y demás el modelo bluetooth es más versatil. Si tu pc no tiene bluetooth pues tienes que buscarte un usb- tarjeta bluetooth primero.
En genral es un buen dispositivo, siempre que tengas claro que no es dispositivo principal sino una ayuda a tus otros ratones, trackball o lo uses.
it's true that hand to keyboard switching is slower than a trackball. But depending on the usecase, this thumb operated can be a god send. Where I'm at, the temperature hovers around 10 degree celsius. it's more comfortable to have your hands in your pocket than out in the frigid air. In this situation, the small size and the light weight mouse works very well from the comfort of my pocket. Pair with an onscreen accessibility keyboard, you can use your computer with your hands ensconced into the warmth of your pocket.
And if you attach a handphone strap onto the tail end, you could slip it into your cuffs, when you need your hands for other things.
I've leaving out a star because there should be another button with which can be used together with rolling the ball.
