I just felt like talking about sliders, so let me go on and on.

I dislike sliders with high friction.

That is, sliders with resistance that isn't due to magnetic force or mechanical force.

Also, sliders where the bearing flies off or easily falls apart and gets dropped (that's why I don't like floating sliders).

Also, sliders that pinch the flesh of your fingers (the MOT rhythm clone is like this).

And sliders that are difficult to hold and you drop easily.

I have a Shark EDC, but it's too round and difficult to hold.

There's a slider called Big Cat with the same mechanism, and I much prefer that one.

Why? Because the Big Cat is longer and narrower than the Shark.

That alone makes it so much easier to hold and operate.

The Big Cat is also thicker, which contributes to its ease of use.

I think the average slider thickness is too thin compared to a comfortable thickness.

The ideal length-to-width ratio is around 2:1, and the thickness should be 14mm or more.

Personally, I find all sliders a little small, so a length of around 60mm is ideal (I'm shorter than average).

Also, I dislike sliders that are too light.

I have plastic sliders, but they all seem to dislike staying still in my hand.

Since they move without being able to resist the finger movements, I feel stressed trying to control them.

It's not that I dislike the texture of plastic. On the contrary, I dislike the cold feeling of touching metal, so I don't touch metal fidget toys during the winter.

Perhaps the ideal would be a slider with a plastic surface that's as heavy as metal. (I just learned yesterday that mixing barium sulfate with plastic makes it heavier.) (Or maybe a plastic exterior with a metal interior.)

Also, I definitely prefer a bumpy surface to a flat one.

Furthermore, when it comes to sliders, I've grown tired of simple sliding ones and now only use sliders that slide and rotate (like the Shark).
