Orbit K72337Us Trackball Wired Mouse with Scroll Ring (Black)

Reduces the wrist pain which is there with regular mouse. Accurate but needs cleaning once a week. * After about two months of usage, now it feels very smooth initially I was not too happy. It's expensive but worth it. Very comfortable for large hands( I have large hands). I use without restpad which did not suit me. The bearings are tiny and made of plastic so not sure about durability. Scoll wheel is better than any mouse scrolls. Large and grippy. It gives you amazing feel due to large size. Scroll wheel is not excellent due to POOR quality bearings but much better than tiny scroll wheel on mouse. Left and RIght buttons are again large and tactile need getting used to. They are meant to slightly hard otherwise there could be false clicks by mistake. No complaints here. Using the downloaded Kensignton tool, I have made dual click as 'drag' and it is very very helpful. ***** giving it 5 stars as it is the best product in this range and nothing else comes close in spite of it's shortcomings. Most other trackballs have smaller balls which is not what a trackball should have. Scroll ring is unmatched too in spite of it's flaws. This trackball is highly recommended for day to day use as well as for work like video editing, CAD drawing, etc.

Its very good product.. at starting you may feel slowdowns working speed, but after all.. you will adjust with it..it gives comfort to your wrist… only thing you should has cleans it regularly…

Works as intended. Except is left clicker starts malfunctioning every 12-16 months , so just keep that in mind

I love this product. The hardware is smooth and easy to use. The trackball is simple, responsive and easy to get used to. The button placement is just right for medium and large hands. And it should work well for small hands too. The ball is easy to remove and clean. Unlike a mouse the device doesn't need much room. It doesn't move physically on the table. One of the best things about the product is the scroll wheel. It has a superb feel and can be configured to move through pages fast and smoothly. This is a big step up from a regular mouse. The software Kensington provides is a little limited but does the job. There are many ways to configure the buttons though which I really like. This was my first trackball and I was initially a little skeptical about whether I'd get used to it but it didn't take me more than a couple of days. And I mostly won't go back to using a regular mouse again because of how responsive and smooth the trackball is. There are other products in the market and some may be good but this trackball is one of the best value purchases I've made for ergonomics and I'll happily recommend it. Caveats - don't expect to use this for gaming. It is great for productivity, art, coding and spreadsheets. It also has only two buttons which may be limiting for some. It works perfectly fine for me though

Need to clean the ball skates everyday which are just cheap red led-like plastics. no teflon, no proper ball skates. very cheap product at 4.3k price tag is, well, i regret buying this thing. also clicks feel cheap like Rs.250 Mouse or Mice. the rest of the product is fine. UPDATE: used for 1 month, left click is already failing.

This is the best range of trackball mouse. Highly recommended for anyone who has to use a mouse for an extended amount of time. Will save you from long term wrist pain. Especially appreciate the service team. They will address all your concerns in a highly professional manner.

Excellent product. I really like the trackball which is silky smooth. I also like the scroll ring and it works perfectly fine. For first couple of days, it requires some getting used to, but overall a good product. I was worried if I should switch back to a cabled mouse, but since there is no movement- this is fine. Also, it reduces the need of the batteries. My hands are fairly large and it works very well. I did not require the extension support that is supplied.

Overall the product is Good, but it is not easy to use, I'm using it mostly for CAD but sometimes get frustrated maybe it will take more time to get perfect on it. One pros is, it's a perfect show stopper, Every one wanna love to see, use and talk about it.

Rien à rajouter

El Trackball para labores cotidianas es destacado, preciso, se mueve como la seda, el scroll es muy bueno, pero yo encontré 2 inconvenientes. 1.- Tengo una PC de la empresa que tiene restricciones de administrador y por políticas de seguridad, no te permiten instalar controladores o software ajenos a los que dichas políticas permite. Al instalarlo en esta PC no lo reconoció, esto seguramente a lo antes mencionado, y la compra fue pensada para utilizarlo exclusivamente en esta PC, ya que al ser USB debería tener una latencia muy baja comparado con el wireless. 2.- Lo intenté probar en mi laptop y ahí reconocí todas sus bondades. Pero tiene un pequeño gran inconveniente. Yo ocupo demasiado seleccionar con click izquierdo y moviendo el mouse, puede ser texto, pueden ser celdas de excel, notas, etc. Es el pan de cada día en mi trabajo. Esta acción en el Trackball no es cómoda, al ser tan rápido en su respuesta, incluso bajando la configuración de velocidad, hace que cuando seleccione texto, celdas, etc, cometa muchos errores, porque en lugar de utilizar el índice como lo hacía en el mouse convencional, debo utilizar el pulgar y con el índice o dedo medio, seleccionar lo que necesito. Al ser tan sensible el Trackball la selección que se hace ya no es precisa, se mueve demasiado por que cualquier roce accidental de la pelotita ya te cambió la selección que habías hecho y tienes que hacerlo de nuevo. Esto hizo que en muy poco tiempo de probarlo me terminara doliendo casi igual la muñeca que con un mouse convencional. Esta es mi experiencia, definitivamente me lo quedaría si fuera Wireless y para mi uso personal, pero para lo que lo necesitaba, que es trabajo de oficina en casa, no es lo que estoy buscando. Iba a aventarme un "tiro" con los de sistemas para que me permitieran instalar el controlador para usarlo en la PC del trabajo, pero al tener esa mala experiencia en lo que es seleccionar con el trackball, he decidido mejor devolverlo y buscar algo que se adapte más a lo que requiero. Pienso comprar uno wireless en el futuro pero para mi laptop personal, donde esta acción de seleccionar no es para nada recurrente, es decir para cosas sencillas, para eso el trackball es perfecto, pero para mi trabajo definitivamente no.

These are great, sensitive, accurate

昔からトラックボール色々使ってきましたが（ロジクールとかエレコムとかマイクロソフト）、１年前に購入使いやすくて愛用、先日ノートPC買ったので２個目購入、もしも壊れてしまったらまたコレ買うと思います。製品の寸法 115ｘ140x46 ケーブル1480ｍｍ

I've had the trackball for about a month now. I bought it to replace the wireless Mighty Mouse that came with my Mac 'cause it ate batteries like no tomorrow. VERY, VERY pleased with the trackball. It took me about a week to figure out how to comfortably use it as I had exclusively using a Wacom tablet in place of the mouse, before deciding to get some sort of mouse. The software: To start off, for those reading reviews of those complaining about the program, you CAN plug and play it. You don't actually need the program for the trackball to work. The mouse adjustments that you can make in the System Preferences will still work for the trackball. However, in order to access the additional features, you will need to download the software. It's a very easy process, just go to the website, download and install it (the instructions come in the packet). The icon will show up in your System Preferences window under the Other header. I don't know where it appears for Windows as I've only transferred the trackball between our Macs. In the trackball program, you can adjust the usual features (scroll speed, click speed, etc) and also the left/right combo click which you can set to do stuff like go back or forward. The program also allows you to choose which direction to have the scroll ring turn to go up or down. The default is set to clockwise for scrolling down. The buttons: overall, they're pretty standard in function. However, I do find that sometimes in certain programs like a Flash game, it won't always want to click on the first try, so I wouldn't recommend this for gaming purposes for games where you do need an immediate response. All other uses, I haven't really noticed any problems. I love the option of being able to set the dual click to do something :) As a first time trackball user, something else I also had to remember to do was take my fingers off the ball before clicking as I often catch myself nudging the ball when I click and then missing the spot I wanted to click. Same goes for the scroll wheel. I seem to subconsciously fiddle with that too. Trackball: No issues with it at all. It took some getting used to with adjusting from a mouse or my tablet and I found myself trying to click on the ball itself a number of times. *lol* But no fault of the device. The scroll ring: So far, I haven't experienced any of the major problems that have been complained about so far. Up till about a week ago, I hadn't gotten around to looking into the trackball's software and once I did, it made a huge world of difference with how smoothly the ring scrolled. It felt a little slow, previously to the point where it sort of staggered sometimes. I love how I can now just give the ring a quick flick with a finger and I'll be back at the top of a web page. I've actually caught myself trying to do that with a scroll wheel on a mouse at work and wondering why it just inched up instead of flying up where I wanted it! Keeping in mind of the complaints though, I have been careful with the wheel and trying not to use it when I don't feel I really need to, as not to potentially abuse it to death as I really like it. So if I'm scrolling to skim an article or search it for something, I'll use the scroll bar on the browser, which with the trackball is pretty effortless. Extras: It includes a wrist rest that you can attach to the end of the base. I didn't bother with it as my desk has a built in one. Size of whole unit: it's a decent size for me. My hand length is about 7 inches and the size of the unit allows me to perch my fingertips on the ball and comfortably roll forward to the middle joint of my fingers if I want to do one long continuous drag. I've play tested some older trackballs in stores many years ago when the majority seemed to be a lot larger, so this works fairly well. Advice: if you find yourself needing to clean your trackball, don't use Clorox wipes. It leaves a sticky residues that slows down the ball's spin. I just pulled out the ball and washed it with hand soap and water, wiped out the dust in the holder, dried off everything and stuck it back in. User troubleshooting: If you find that your hand is more tired using the trackball than a regular mouse, try adjusting your chair height. This can make a very big difference. If you have an arm rest on your chair, take advantage of it and adjust your chair height to make the rest level with your trackball.
