Hello #networking people. I'm wondering if it makes sense to buy the more expensive (~70€+) #fiber cleaners/pens, or if the 10€ ones from china do the job comparably well. Any experiences and maybe even comparisons using a fiber scope that someone can share?

context is either
- use for small home networks and occasional lan parties, or
- use in dirty & rough environments at events to connect equipment between stage and FOH.
