Review on Pack of 6 Febreze Small Spaces Air Freshener, Wild Berries: Strong Odor Eliminator by Melvin House

6 of these have been open for 2 days now in a small 2 bedroom flat and I still notice just a hint of smell). So far I think they would be great for closets, but not for a 20x10 room. And I've noticed a lot of feedback on the different levels of liquid in them. Same for me. 4 of the 6 I bought were less than half the height. And the other 2 were slightly above that level. Most of the stock photos of this product that I've seen were almost fully packaged, so maybe this is a quality control issue at the manufacturing company or just a way to sell a bad batch?
