So I actually tested this on another car before using it on the M2 I haven't used it in the M2 yet because of the cons below.

Pros: picks up dust and lint, conforms to irregularly shaped surfaces and small crevices, cheap (price)
Cons: LEAVES A RESIDUE, does an OK job of cleaning, cheap (quality).
I also have the below gel stick that I use for my camera's sensor but I haven't used on the car yet because it's tiny, so it would take forever to do the whole gauge cluster. If the above product is more like the sensor gel stick, I think it would be a better product overall.
