Those are both airflow holes. The small one is permanent, but the larger one with the screw is supposed to be adjustable.What the hell is that little screw supposed to do anyway? ... and there is also an even smaller hole on the outside of the base (too small to even have a screw in it) .... What's that little hole for?
Where are you guys finding the black edition KFL+ ? I bought one on eBay several weeks ago (and love it) and I'd like to get another. I'm not seeing it anywhere on ebay...but my eyes aren't what they use to be![]()
Keep an eye on the vendor, he should be getting more in next week and creating a new listing.
