SlimBlade™ Pro Wireless Trackball, Rechargeable Battery, Bluetooth 2.4GHz Connection Options Black/Gray (K72085WW)

This is a solid well made piece of equipment. The operation of the buttons has some clanking, but I rather like that feedback. The function of the 4 buttons & button-combination is completely customizable with many options for the action that's taken. I just love the twist-&-scroll ability, where you twist the trackball & whatever page you're in slides up or down. It's so much faster & easier than shuffling over to the slide bar at the right of the page, & sliding down manually. For me, this alone was worth the purchase. After a month of using the trackball for many hours, the charge level is still at 100%. I use the trackball on a Bluetooth connection. It's fast & reliable. I am very pleased with the smooth & silent operation of this trackball. Having a large ball is really useful for me to keep control of the mouse over a very large screen. If you've only ever used a mouse, expect a period of adjustment for you to get used to the operation & feel of a trackball. But, this is the best. A little regular practice, & you'll find this fast & more accurate than anything you could have done with a mouse.

Having used the traditional trackball for more decades than I can easily remember I decided to switch to the slimline version about 3 months ago. The "wheel" on the traditional always made an annoying sound and the weakest point on it. The "wheel" on the slimline is not physical but senses when your finger is close to the circular area around the ball, meaning there is no ring anymore and you simply get close to or touch where it used to be and spin the ball to get the same effect, and it works well once you realize how to control it. It is smooth and easy to use. The track ball is the same size and are interchangeable. The socks the ball its in has some nice improvements, gone are the tiny balls use to give it a smooth roll and always collected dead skin and dust and replaced with simple indents doing the same without as much collection. Then at the bottom you now have a hole where dust will fall out through. This makes it less sensitive to collecting particles and easier to clean. You have a choice to use bluetooth or USB cable. The buttons can be harder to click on since you now have to click closer to the center unless you press a lot harder than normal. Not a huge deal but a change. The only real issue I've started to run into namely battery life. The specs lists 4 months or charge, that was good until 2 weeks ago and now it drops to 25% and gives a flashing red-light to let me know the charge is low. Now I charge it once a week. Though annoying it does charge up pretty fast. For all that use this brand of track ball you know they are well made and this is no different and maybe even better. Inserting the USB C connector does require a much harder push, something probably made to ensure it does not fall out easily. And for everyone else, if you ever had an issue with your mouse, try a track ball mouse but one with a large ball. Small ones do not give the same control (more sensitive). --- UPDATE: Called support and they are shipping a new one, can't complain about that!

I came across the Kensington Trackball about 35 years ago and it was just a very simple plug-in device. I have not gone back to using a regular mouse, or a trackpad since I started using the Kensington Trackball. It cuts down on hand fatigue, is much more precise in its movement and I’m sure it helps to prevent future issues surrounding carpal tunnel syndrome. The Trackball remains stationary and you gand works the ball & buttons. Everything is faster & easier with the Trackball. The Trackball has two left-keys & two right-keys, which can be programmed as left-click/right-click, with the remaining keys able to be programmed to snap to websites, email, etc. This is a very versatile product and as I said, I’ll never go back to using a regular mouse or a trackpad again. They are a pain. It’s the perfect merging of a keyboard and the ability to move your cursor around your page , highlight, cut/paste, etc. with speed and precision. FIVE STARS FOR THE PAST 35-YEARS & MOVING FORWARD.

Wygląd kosmiczny, niski profil, duża kulka, precyzja użytkowania bardzo duża, a scroll wheel jako Ruch kulą to game changer.

I work only with trackballs - all kensington - this model is not really usable for me as it is jerky and the center ring which was the main reason to stick with Kensington track ball has opposed to other cheaper versions who work better has now been replaced with a 'Ball Twist' Motion which not only is not really functional but also interferes with normal mouse movement. I truly dislike this ball and i am trying to return it.

This trackball is simply top notch, as far as I am concerned ! Very comfortable to use, low profile, ball is so easy to spin and use, I love the way to scroll while spinning on its axis the wheel while my fingers turn around the base, switches are lovely, nice click, nice sound, nice feeling, glossy finish is nice to touch in the hand ... Bluetooth works great for me (better than my previous 2,4GHz dongles for my older trackballs). Everything on it has been well thought out and the result is an excellent product, well worth its price. Highly recommended (for trackball lovers) !

Recensione riferita al modello Slimblade Pro Wireless (ricaricabile, wifi / bluetooth). Trackball estremamente scorrevole e piacevole da usare: trovando l’equilibrio giusto tra software Kensington, risoluzione dpi e settaggi mouse del computer, si raggiunge un’esperienza d’uso senza pari. I tasti ampi si raggiungono e si cliccano agevolmente, con grande naturalezza: la mano è chiamata a fare movimenti organici, mai forzati. Comoda la possibilità di assegnare funzioni a combinazioni di 2 tasti: non solo tasto Sx + tasto Dx superiori e inferiori, ma anche tasti superiore e inferiore su ciascun lato, per un totale quindi di 8 funzioni assegnabili. Questo è un aspetto che non ho trovato illustrato in modo chiaro mentre valutavo l'acquisto, quindi allego schermate (a rischio di essere ridondante). In qualsiasi momento durante l’uso, ruotando orizzontalmente la sfera si entra nella modalità di scroll (con aggiunta di rumore meccanico sintetico, a simulare il cliccare di una ghiera). Il passaggio tra la modalità di tracciamento e quella di scorrimento è liscio come l’olio, il suono di clic è l’unico segnale che si è passati da una modalità all’altra. Lo scroll ha luogo sia ruotando la sfera con due dita come fosse la manopola di una cassaforte, che facendola scorrere con un solo dito. La naturalezza con cui si torna al tracciamento (e viceversa) è davvero sorprendente, il tutto si svolge nella massima scorrevolezza. Il design forse è un pochino troppo futuristico e al contempo la scocca è molto plasticosa, ma la sfera sembra di ottima qualità, con un bel peso e piacevole sensazione al tocco. Il prezzo è sicuramente elevato (si trova spesso usato se si vuole risparmiare qualcosa), ma sono molto soddisfatto dell’acquisto.
