perixx PERIMICE-520 Wired USB Ergonomic Trackball Mouse, Adjustable Angle, 8 Button Design, Black

I purchased the Perixx Perimice-520 wired mouse to replace my Logitech Trackman T-RB22 which seems to have finally given up the ghost after about 18yrs faithful service ! The fact that the Perixx is not wireless is no issue for me in my use whatsoever. But as photo/video editing is my thing, comfort is paramount and I thought I would give this a try given the two angled bases supplied, which enable you to have a choice of customising the angle at which the mouse sits in order to give better comfort. I found this to be a real benefit and has reduced any discomfort due to long periods of use. It is a rather large unit but again, not a problem, in fact, for me, it adds to the comfort. Combined with the available customisation and smooth trackball, I am more than satisfied with the Perimice-520.

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.

I have arthritis in my right wrist, so was looking for an adjustable ergonomic trackball. I love the 3 options for angle- never seen that before. I'm using the greatest angle, so need a wrist rest too. Made of smooth plastic, not the stuff that goes tacky after a couple of years. Programable buttons if you want them. I would never go back to a normal mouse, I'm sticking with a trackball, and this one is perfect. I bought the one with a cord, the cheaper option and perfect for my needs. The extra bases stay on with magnets- ingenious.

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

First time using a trackball and I found it very comfortable and after a week am now used to it, great addition is the extra plates for getting the right angle for your hand to sit on it and a good price.

I got this to use on a smal desk with a laptop. It performs that way very well. It comes with two different clip-on bases to put the mouse at steeper angles (the lower one was the more comfortable) and has several prgrammable buttons. The only issue I had was that it's basically a mechanical mouse -- there are roller wheels under the ball that require regular de-linting to keep it working efficiently. The ball is easy to remove but I reckon this is something that could only get worse over time. I eventually got a larger desk and this went ina drawer. It's still a useful thing to have and better than a spare "standard" mouse.

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.

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...

Sto usando questo mouse da 1 settimana e mi trovo benissimo. Premetto che uso il PC per almeno 8/9 ore al giorno e lavoro su dati ( email, excel tantissimo), passo a questo mouse da uno normalissimo .Mi sono abituata subito alla trackball, non è precisissima ma per il mio utilizzo è perfetta ( per AutoCAD non saprei... Forse non sarebbe abbastanza scorrevole). L inclinazione è fantastica, io ho provato le 3 altezze e per ora ho scelto quella centrale. I dolori spalla gomito si sono alleviati da subito. Devo ancora provare a personalizzare i 2 tasti. Per ora molto soddisfatta, lo consigliere per chi ha un un uso simile al mio

Having this mouse is best thing I've done. Spend a lot of time working on the computer, and the hand position and pointer control is very good. I thought the ball would become "sticky" as the older ball mice, but I've only had to clean it a couple of times in 6 months.

Je me sens bien avec ce souris est vraiment confortable travailler avec
