Room Air Freshner

I don't really like candles, so I thought this would be a great alternative.

Problem

I can not smell this at all!  Even standing next to it!  I put extra scent into it and waited another day or two, and then put more scent into it - still don't smell it!  This sucks because I love cucumber melon scent!
