Kensington SlimBlade™ Pro Wireless Trackball, Rechargeable Battery, Bluetooth 2.4GHz Connection Options (K72080WW)

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!

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

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) !

Durable , and also satisfying to scroll with

Funktioniert recht gut, es ist definitiv eine Umgewöhnung es geht. Das einzige Problem das ich hatte war das die Anbindung über USB einen Driver verlangt, was mir nicht ganz eingeht weil eigentlich müsste er wie jede Maus Funktionieren.Auch das Scrollen mit dem Ball funktioniert recht gut.Ich nütz e den Treckball für meinen Medienpc am Fernseher, ich hatte mit der Maus immer das Problem das die Maus nie da war wo ich hin griff, wenn sie nicht gerade auf der Couch rutschte und mir den Fortschrittsbalken einblendete. Der Slim Blade steht immer leicht zu finden am Tisch und macht dort eine gute futuristische Figur, der Rote Ball passt auch sehr gut zu Netflix und YouTube.
