perixx PERIMICE-720 Wireless 2.4 GHz and Bluetooth Ergonomic Trackball Mouse, Adjustable Angle, 2 DPI Level, White

I have been using Logitech 'Trackball' mice ever since they arrived in 2001 and never changed even though I've tried others, they were never, ever close. I decided to try this mouse because I really wanted a 'wired' trackball (thumb) mouse. What a brilliant design! So far it's been great! The buttons are shallow and smooth to the click. The ball is in perfect position for my hand and the the height is very comfortable. It is performing very well so far and I even like the purple colour of the ball :P I really hope the ball stays smooth over the coming months as some trackballs become scratchy after a while...here's hoping! A great price for a great product.

The Logitech M570 wireless trackball is my go-to for pointing devices now - it dramatically reduces arm movement across your desk, and only requires the footprint of the device to rest on to be usable. My one criticism is that the M570 is only available in a wireless variant; for something that (usually) lives on my desk, and unlike a mouse does not need to move from its spot, the wireless aspect adds more trouble than it solves. This trackball is very similar in design - it uses a thumb ball, has navigation buttons and even an adjustable base angle - but it's wired USB. So no batteries and no wireless interference. The ergonomics are very similar and it's extremely comfortable to use day to day. It has a few additional features over the Logitech trackball too - first it has adjustable DPI sensitivity, it has an Alt-Tab button to switch windows mounted below the scroll wheel, and the wheel tilts for horizontal scrolling. These are all very nice additions. It has a generous USB cable length and very clicky buttons, so you have positive feedback. The downsides are that it's not quite as nice quality plastic as Logitech use - the build quality seems less when you go from one to the other. It's much lighter and not as keen to stay in one place on your desk. The ball is also lighter; this means it has less momentum - one of my favourite tricks is to flick the ball and have it carry the cursor all the way across my large screen (or dual screens). This works, just not as well as the Logitech one. For cleaning, I can extract the ball from the Logitech with just a finger, but I have to use a pen or similar to pop the ball out of the Perixx one. The Back button is easy to push, but the Forward button is located closer to the edge of the mouse than the Logitech one, so it's a little harder to click. Also, the tilt wheel is quite firm and requires a good push to engage horizontal scrolling, needing a firm grip on the mouse. One final difference, the Perixx uses a red LED optical sensor, whereas the Logitech and most newer mice have moved onto invisible optics; it's not a problem, just a bit interesting to see what feels like 'old' tech. Overall, not perfect, but an excellent trackball for those who want the ergonomics of the M570 with a wired connection.

Good quality product, well packaged and easy to set up. I use one of the two plates fitted to the bottom of the mouse, to achieve the correct angle for my hand. I find the mouse to be a little too responsive at times - the cursor speeds across the screen sometimes, but overall I'm very happy with it. A worthy successor to my old Logitech mouse.

It's a good rollerball. Like all rollerballs, you will need to occasionally 'pop' out the ball to clean any dust from the sensors (usually the end of a biro works), plus clean the ball itself (important in these virus days - hand santizer will do). I am currently using it with a Chromebook and it has no issues with that. You can also use it with a bluetooth connection. Using a rollerball for the first time does take a bit of practice 'cos you will try and move the whole thing instead of just rolling the ball.

Works well, used for sometime now with mo issues. Happy customer

Very Comfortable, responsive trackball but ultimately useless after the scroller broke - It gets stuck in a cycle of going up when you scroll down, then goes back and forth small amounts repeatedly, has even done it when your not touching the mouse. Seems to be a recurring problem, drivers up to date & no info on support page, Replaced with another brand.

I don't write many reviews, but this device deserves some praise. I previously had a Logitech trackball maybe 20 years ago, and recently bought a new one for my new PC. In 20 years as an Amazon customer, and having bought thousands of items, the Logitech mouse was the first item I had to return. It didn't work properly and it had very poor build quality. I replaced it with this mouse, some £15 cheaper. It's not programmable, but as a mouse, it's perfect. The ability to raise the mouse using one of two supplied stands wasn't something I really cared about, but it turned out to be a valuable feature. I found the mouse more comfortable when it was raised up slightly. The stands are held in by magnets, and are easy to change for different users. The ball is easy to remove for cleaning. You just push it up from below, and it pops out. I can recommend this mouse.

I needed a mouse/trackpad for my HTPC, using wireless at 5M distance was always a problem, especially after trialling a number of different WIFI mice and keyboards! Hence I decided to go for this Trackball mouse as it has a Bluetooth option. It seems to have resolved the connectivity issues from a distance, I do get the odd lag but I'm not sure if that's the game/video I'm running or the mouse itself. Overall it's a great product especially when compared to the other brands that charge so much more.

The product worked great for the first 4 months. Sadly the scrolling wheel broke down. When I try to scroll down, it will scroll down and then up again. With this defect the mouse becomes unusable for me. Update: the mouse started working normally again. Still confused as to why the problem started and why it is working again.

J'avais souvent employé par le passé, des trackball, pour finalement retourner à la souris classique. À mon avis, le trackball est à réserver à des usages spécifiques, où l'espace est compté, ce qui est le cas pour cet achat. En cas d'usage intensif, il y a quand même une grosse fatigue du pouce... C'est peut être pas dramatique, mais les tendinites peuvent être très gênantes et compliquées à gérer. Ce trackball est de très bonne qualité. Je n'ai pas hésité à racheter du Perixx, car, que ce soit les claviers ou les souris, je n'ai pas été déçu. Pourvu que ça dure...

Der Trackball ist echt nicht schlecht! Er passt unter meine großen Hände was schon mal nicht selbstverständlich ist. Die Winkelstücke hab ich ausprobiert, ohne Adapter ist aber am besten. Look & feel ist nicht gerade hochwertig und auch die Lager für den Ball sind aus Plastik. Muss aber sagen in der Praxis taugt er. Ich kann noch nichts zur Langlebigkeit sagen, habe ihn erst 2-3 Wochen in Gebrauch. Den Ball nutze ich für CAD Zeichen und Musikproduktion und das macht er wirklich gut. Habe auch verstanden, dass die Kunststofflager des Balls besser gleiten. Er läuft auch tadellos unter Linux- einfach - alle tasten sofort da. Alles was mir an dem Trackball fehlt ist ein besseres Mausrad mit Schalter für Freilauf.

I have used the M570 for many years. I like the trackball because it is comfortable to use without straining my hand. Recently one of the buttons stopped working so I looked for a replacement to my M570 and found Permice 520. The Permice is slightly cheaper and it has a wired version. I preferred wired as I don't move it like other mice so I am not sure why Logitech doesn't have a wired version. They function more or less the same way as expected. The Permice is slightly larger but it was not difficult to get used to. There are two additional ergonomic adjustments available which are nice. There are also more buttons than the M570 which can be useful for gaming. The only problem I have with it is its sensitivity. It has L and H for slow and fast respectively. I played around with my setups and couldn't get it to the speed I like. It either goes to slow with L or to fast with H. I am sure I will adjust to it eventually. It feel solid and well build and I recommend it for its value.

The mouse is pretty bulky and is suitable only for very large hands. Two plastic attachments are provided that tilt and increase the heigh of the mouse. The trackball play is not super smooth but gets the job done. It does not look like any of the buttons are customizable. The Bluetooth connects pretty quickly on windows machines. But there is no option to save/switch Bluetooth connections. You will have to pair again to each machine that you want to connect to. Uses two AAA batteries.
