Excellent office trackball.- It's easy to use- It has plenty of buttons for customisation and software to remap them- Small enough to not get in the way but still comfortable- Accurate with very little lift-off (better than the huge trackball in this aspect)- Very useful scroll wheel. Trackballs without a scroll wheel are annoying.- Lightweight and easy to carry- Wireless, so no cables to deal with.- Sufficiently sturdy plastics and no sticky rubber.- Good price for a trackball.The only downsides are- The back and forward buttons don't work on a Mac- The polling rate isn't high enough for gaming (you get aliasing problems).

Great design and feel. I went from a Logitech trackman to this. It is smaller than the logitech which is can be a bad or good thing depending on you hand size. It is comfortable for me. Only thing I had to get used to is the right click button. It is small and not the same size as the left click. Its not too big of a deal, you just have to reposition your ring finger when holding the mouse. There are a lot of buttons that you can customize which you don't have to use if you don't want to. It has a scroll wheel with back/forth buttons already program. Overall i'm happy with purchase especially at the price point.

El tamaño del mouse se ajusta muy bien a mi mano, permitiendo que la muñeca y antebrazo descansen sobre el escritorio sin necesitad de un mouse-pad, es ergonomico

This trackball was a nice upgrade for me from the Logitech Trackman Marble, which doesn't have a scroll wheel. It takes a little bit of time to get used to the buttons, but then it's very comfortable to use.But after about 18 months of daily use, the micro switch for the button I was using as my left click started failing (one click registered as two clicks). I had to take it apart to replace the switch, which is not a trivial task. The original switch was a Made in China Omron D2FC-F-7N 10M, and I replaced it with a Japanese one.

I wasn't sure if I would like this or not, but this one is a keeper! I have always hated the trackball due to it causing my thumb joint to cramp up, but figured I would give this a try. I am NOT disappointed! I don't get the cramping in my index finger, as it remains extended most of the time. Only noticed some discomfort after 3 days of 14 hour stints on the computer.I use this for design work, drafting in a 2d/3d environment, so precision and freedom of movement is what I was looking for. I love that I am not moving a mouse around, just my finger. I was concerned it would be hard to get used to left clicking with my thumb, but it comes more naturally than you would expect from a lifetime standard mouse design user. I programmed the 3 top buttons for copy, paste and undo, but old habits die hard and I forget to use them as much as I should, I manage to use my keyboard shortcuts before I remember those buttons!NEED IMPROVEMENT:Website to download the software (only if you want to program the mouse buttons- it works without this) is mostly in an Asian language, so not easy to know you are downloading the correct item.Instructions are printed in MINISCULE print- including the web address for the software.Side scroll wheel needs improvement. Hard to tell if you are selecting or tilting until it is too late. It works fine, but sometimes when pressing down and holding you go from normal scroll to tilt even though you are not trying to. Maybe if the location was further forward it would help.Left click sometimes seems a little stiff on the double click (like you can't do it fast enough) it is probably due to the fact the button relies on the forward/tip of thumb pressure versus the entire button (which does help eliminate accidental clicks due to grip).Could really use a wrist rest!!

Este es el segundo que compro y llegué a él después de tratar el Logitech M520, M570 y un mouse vertical. Este modelo me resultó el más cómodo ya que un mouse convencional me ocasiona muchas molestias en mi extremidad, cuello y espalda. Me gustan los botones programables para cada aplicación, es decir, puedes programar, que el mismo boton haga algo distinto dependiendo de la aplicación que estes usando y combinando hasta tres teclas simultaneas en cada boton. Las "desventajas" son la duración de la pila (unos 3 meses), no es muy preciso y el software puede ocasionalmente no reconocer la aplicación que usas haciendo que los botones programable no respondan como deben. En general, si tienes problemas de mobilidad y no requieres mucha precision, es una excelente opción.

All in all a great product. Size, feel, quality all on par or better when you consider price. I bought this one just to try it out and see if the company was legit. I can honestly say that i am more than sold on the company and the quality and i have no reservations about spending considerably more for one of their high end models. Im actually excited to see this company's high end features bells and whistles.. The only real issue with it is customizing the extra buttons. The software they provide is garbage. And to make matters worse, isnt even in English. You will have to find another software to customize the 6 7 8 buttons. This is the issue that keeps me from giving it 5 stars. But other than that, its terrific. Fast, accurate, comfortable. And at fair prices... i highly recommend.UPDATE: Its now 2023. Ill save u the details but I was asked to give my opinion on ergonomics as it relates to office workstations. I was given the opportunity to do some research on several companies including Logitech, Kensington, and Elecom. The funny part is no one on the team had even heard of Elecom before my recommendation. Comes to find out, they chose Elecom mice for every new workstation in the facility including the main dispatch center hub where they no doubt are going through a trial by fire. And not a single complaint has come up about the performance, and they were actually praised for their customization as dispatchers like to program their mice with their own shortcuts for maximum speed and efficiency during their shifts. So I must retract my initial review about their programming software and tell you that it's much improved. And that's not just from me. That's from a whole 911 dispatch center crew of over 30 dispatchers who have no skin in this race. I'll be honest I forgot about this initial review and never would have paid any attention to it if I had not given it a poor review initially. I stand corrected and concede that improvements are the new order of the day. So Elecom gets the 5th star. Oh, there is still 1 tiny issue... The product info is still written in Japanese so you have to go to the Elecom website to get it translated to English. Lol. Pound for pound.... And I can't believe I'm saying this... Better than Logitech and Kensington. Elecom quality and price is equal, if not better than the big guys , and they offer more innovative options to their products so u get more for your money. At the end of the day, Elecom is doing what any new guy should be doing., better product at better prices, and letting their performance do the talking. And again, Elecom doesn't even know I exist and they don't pay me a single dime to say any of this.... I just believe good quality products should get a little recognition every now and then .
