Using Trapo that has the locking mechanism since my car has it. So no sliding around.

Good: Traps dirt and liquid very well.
Bad: You WILL see the trapped dirt and liquid very well.

But at least it's very easy to clean though. Shake and put back can already, no need to whack also. I clean my car every weekend so it's relatively easy to maintain for me.

In my previous car was using those thick ones that has wire "mesh/wool" type. Those are a pain to clean and I've replaced 3 or 4 because my heel would grind a hole in the meshing and it just falls apart.
