Your Best Studio Buddy!
This product has found its home in almost every professional recording studio in the world. It is extremely dextrous and such a comfort to the wrist. Long hours at the studio don't seem so long anymore! The only issue I have noticed is with the scroll wheel not performing smoothly, but it still works. The trackball is weighted and has sufficient momentum to sen e cursor flying to the other end of the wide screen display. Integrates very well with Pro Tools, and general workflow. I am yet to try out the customisable top keys to instantiate macros. Very satisfied with the product finish and quality.

A fantastic Trackball
I think this is a fantastic mouse for doing colour jobs in Resolve. The huge trackball with proper tactile feel is perfect for precision. The scroll button works like a charm. I had to fiddle around to find the middle button click, but once that was done everything fell in place. Saves my wrist.

Worthy tank
I bought this after experiencing pain on my pinky finger due to traditional mouse movements while editing audio tracks for long hours. This trackball mouse is definitely worth in terms of no wrist movements. It comes with a wrist rest which is very comfort for me. But still after long audio editing works, I feel tired to move the ball multiple times and mainly the scrolling is not at all smooth. I read that it is designed in that way. There are however options to program the 4 buttons in combinations of single button as well as double button pressed simultaneously. You must install a small program for this option. For example, I have programmed one button as click and hold, so I can drag things at leisure with free hand. Still some programmed options were not working inside some softwares. I can also program macros. I created a list of contact details which very often I had to fill in some situations, pressing those button gives me a list and click that will be filled into the required area such as name or address in an online form. It is definitely a worth buy as it is solid built and guaranteed by authorised center in India itself, not abroad.

Why are the Kensington trackballs comington goes it's hampering the good will of the company.
I have purchased twice from techchize and received damaged slightly ,and the damages are in the important places the left top button and the scroller wheel. I have mailed Kensington as well because it's a matter of good will for these companies building this and been using these trackball for many years. I have ordered again ,please see to it ,the product is in best condition.

Satisfied for now
So I was using this product at my work place and really liked it so I ordered one for myself at home..I work in the audio video industry so I need really precise movements for automations and stuff.. Initially it was misbehaving a bit.. like everytime I was pressing the upper right button its cursor speed changes.. don't know why but had to unplug and reconnect it then it started working normally..then I had to avoid using that button as the deadline of the project was really close.. but later it automatically worked fine.. I hope it'll work fine in future as well ..

Good for amateur colorists!
I got it as a basic entry level control surface for coloring. I use it with DaVinci Resolve and works perfectly. The trackball software that comes is really good where you can configure the settings of the buttons, scroll ring and trackball for different applications. The mouse is bigger than i expected with a resting pad included which makes it comfortable for long term use.I have used it till now for 4 hours straight and have no issues. Good for amateur and entry-level colorists!

I just got this trackball, first time using a trackball ever, i was delighted by how well this one works. the included wrist rest is really helpful especially for my hnda when on a hard surface, the ball rolls smoothly and with precision, the only slight thing is the scroll ring has a slight wobble to it, but it is not that bad, i am just very particular. but i do really like the scroll ring, i am able to operate the left click with my thumb and right click with my little finger. very easy to use and the optional kensingtonworks software is great, its not needed to use the trackball, but you can set so many options for the 2 programable buttons, the top 2 buttons are great, but you have to be very very precise about clicking both at once when using shortcuts, overall this was an amazing purchase, and i am impressed by the quality of kensington products

Ich wollte schon immer mal einen Trackball haben und hatte leider verpasst mir bei Neuerscheinung einen MS Trackball Explorer zu kaufen (Die Mutter aller Trackballs!). Die Verarbeitungsqualität ist tadellos. Alles ist sauber eingepasst und es knarzt nichts. Die Tasten, der Trackball an sich und auch das Scrollrad sind bequem mit der Hand zu erreichen. Zudem steht der Trackball absolut rutschsicher auf dem Schreibtisch. Die 4 Tasten haben einen guten satten Druckpunkt und das Scrollrad eine leichte Rasterung. Die Software erlaubt die Belegung der Tasten und Einstellung der Geschwindigkeit von Trackball und Scrollrad. Ich kann damit die Geschwindigkeit so einstellen, dass ich mit einer "Drehbewegung" den ganzen Bildschirm abfahre, die Auflösung / Genauigkeit aber sehr hoch bleibt. Die Genauigkeit ist generell sehr hoch. Man kann extrem feine punktgenaue Bewegungen ausführen, was auch an der ziemlich großen Kugel liegt und natürlich an der optischen Abtastung. Durch die sehr reibungsarme 3 Punkt Lagerung der Kugel, ihr stattliches Gewicht und die Größe, kann man zum einen die Kugel regelrecht "anschupsen", zum anderen sehr genaue Bewegungen mit der Maus ausführen, wichtig z.B. bei pixelgenauen Zeichnungen. Die Genauigkeit leidet nur dann etwas, wenn ich Bewegung und Tasten drücken gleichzeitig ausführe. Das ist auch der Grund, warum der Trackball für Games, insbesondere Shooter nur eingeschränkt benutzbar ist. Ausnahme ist vielleicht Portal, das konnte ich mit dem Trackball perfekt spielen. Die Kensington Expert Mouse sollte eigentlich nur als Ergänzung zur Maus dienen, doch hat diese mittlerweile fast ganz abgelöst. Unverzichtbar ist sie auch z.B. in Elite Dangerous, wo mein Schreibtisch mit Stick, Schubregler und Spacemouse kaum noch Platz läßt und der "stationäre" Trackball perfekt für die Mausbedienung ist. Im Prinzip fallen mri nur zwei Sachen ein, die man verbessern könte: Das Scrollrad funktioniert an sich super, hat aber irgendwie eine komische Lagerung. Es wirkt, als würde irgendwo etwas schleifen, es läßt sich aber trotzdem leicht bewegen. Ausserdem sind die Einrastpunkte mit der Scrollfunktion nicht immer synchron. Der Anstellwinkel ist insgesamt etwas zu steil. Der Trackball müsste flacher sein, damit die Hand weniger stark abgewinkelt ist. Hierfür liegt zwar eine Handballenauflage bei, die auch ihren Zweck erfüllt, damit vergrößert sich aber wieder die Stellfläche. Kurz und gut: Das Preisleistungsverhältnis ist sehr gut, viele Alternativen gibt es auf dem Markt eh nicht mehr. Mir fallen hier nur noch die Trackballs von Clearly Superior Products ein und die kosten gerne mal das doppelte. Von daher 5 Sterne und absolute Kaufempfehlung

Très agréable pour travailler avec fusion 360, il est grand je ne le conseille pas a se petites main, la boule est très fluide, et grâce au coussin je fatigue beaucoup moins vite et surtout le canal carpien lui dit merci un très bon achat, ha oui la boule n'est pas fixée et elle est lourde ça fait au doigt de pied
