Perixx Perimice-209 P, Wired PS2 Mouse with 1000 DPI Resolution, Black, (10442)

Great durability. Works better and longer than newer USB mouse. PS/2 devices are better for resilience/latency than USB. Since USB mouse/keyboard devices share a bus with other USB devices, some erratic behavior may occur. Also most USB mouse/keyboard are USB 1.1 and that can cause problems with higher throughput USB devices on the same bus controller. But the build quality vs common USB mice is the real winner here.

Bought it for a 23 year old computer and it works great!

Perfect mouse for a retro build. Fully ps/2 compatible. Works with my pentium 100 system, dos 6.22, Windows 3.11.

Background: I have a refurb Dell Desktop and I used a USB Wifi adapter. I just switched to a travel router and hardwire LAN. My old setup worked but the mouse (Dell wired USB optical) was glitchy at times. I finally had enough and switched to a PS/2 mouse. The ancient, OEM mouse was mechanical, though. The scroll wheel was loud and had a heavy tactile feedback. And mechanical mouses tend to gum up. I wanted a cheap PS/2 optical mouse with at least 600 dpi. I've had s Perixx BlueTooth mouse before that I still have and like. And the price was right. I'm using the Perixx now and I love it!

I use a older (Starview) KVM that pretty much pre-dates USB. For decades I used Microsoft mice, since they came available the dual Microsoft Blue optical with a USB to PS/2 adapter. Because of age I think of my KVM, the mouse became less responsive missing left-mouse clicks, even after swapping to a new (old stock) MS Blue. I tried a new adapter, but as they are passive no change. Issue is with aging KVM and not the mouse or adapter. This Perixx Perimice-209 mice solved the problem and will likely give me several more years with my KVM, perhaps outliving me. If you use a KVM or just have an older computer with a PS/2 port, this is a good mouse. I deducted one star as it's not as comfortable as my old Microsoft mice were; a bit smaller and curve of mouse different but really that is just an adjustment I need to get use to. If you are using a different mouse, this might be a 5 star experience for you.

After years of trying to scrape away every hair from the little roller thingies on those old mouse controllers (the ones with balls) I've finally found an optical mouse that is compatible with my windows 98! That's all there is to it. It works! No extra drivers needed. Smooth. And the wheel works too; though you may need to adjust a few settings or something-- I can't remember. I can't tell you how many of my Sim Farm strawberry fields have been eaten up by bugs while I was furiously trying to get the dumb ball mouse to move! :'D No more!

I got this because I needed a mouse for my DEC Alpha (personal workstation 433a), I still have Windows NT 4 on the beast so I needed something to work with it as the various USB to PS/2 adapters did not work. This mouse worked very well (well enough I'm ordering another tonight and a backup just to be safe). Had no trouble booting up into Windows and never any trouble using it, scroll mouse worked just fine. I also have plugged it into an old HP Core2 small form factor PC (sorry not sure the model, but it is old enough it still says "HP Compaq" on the front under the HP logo) and booted into 64-bit HaikuOS and it actually worked where my USB MS comfort mouse 4500 did not. So to me proves the PS/2 port sometimes is just one of those things that "just works" when USB fails you.

This is a basic PS/2 mouse - the main features are the low power it consumes, and the great price. If you NEED something that doesn't suck down current, this is the mouse for you. I had to hunt down the spec - it's 10ma. Now you don't need to hunt it down. :)

Muy aceptable.

Ottimo mouse per vecchi computer con attacco PS/2 . Avevo su un vecchio pc ancora un mouse con la pallina, questo fa assolutamente il suo lavoro egregiamente, semplice e funzionale.

Werkt perfect. Waardoor mijn oude PC weer optimaal te gebruiken is. Makkelijk bestellen, snel geleverd.

Fonctionne bien pour une souris d'usage basique. J'ai ainsi récupéré un port usb monopolisé par une souris pas plus performante.

I brought this to use is Scada system’s PS/2 port to as to free one of the USB port but it doesn’t work!
