This micscreen really improves your acoustic recordings. I've mostly been recording vocals (but also a little guitar, which dose not not work as well as vocal recordings) with this filter, and it makes your vocals sound more clean, dry and controlled. Depending on the size of the room, it will reduce up to 80 % of all reflections. It's a little expensive, but much more cheaper than to build a sound isolated room - and the quality will be much like the same.
