Perixx PERIPRO-304 Glossy Red 55 mm Trackball Replacement

Replaced the ball on my Kensington Expert and it's like new. The glossy red looks great and the tracking is smooth. Highly recommend.

This ball fits my SlimBlade perfectly. The red color is vivid. Tracking is smooth on my desk pad. Only reason not 5 stars is that it's a bit pricey, but it does the job.

I dropped my old ball and it cracked. This replacement is a seamless swap. The tracking is accurate. The glossy finish feels premium. Happy with it.

The ball works, but it feels a bit too slippery compared to the original. I had to get used to it. Also, it picks up smudges easily. But for the price, it's acceptable.

My original trackball was getting dirty and sticky. This replacement made my mouse feel brand new. The red color is a nice touch. Tracking is buttery smooth. Excellent quality.

I have an old Kensington Expert that needed a new ball. This one fits and works perfectly. The glossy surface is nice. It's a bit smaller than the original? Actually, it's the same size. Works great.

I bought this thinking it would fit my Logitech trackball, but it didn't. It's supposed to be for Kensington but nowhere does it say that clearly. So I can't use it. Waste of money for me.

The red ball adds a pop of color to my setup. It's a bit heavier than the original? Maybe not. It rolls smoothly and accurately. Good value for replacing an old ball.
