Query: We barely notice the smell

We got a pair of this on sale from a local supermarket and we thought it was a god deal. We put one it the powder room and one in our living room. To make it work, you have to open it partially to let the fragrance comes off. I do like the citrus smell, it was nice the first time I opened it. After a few hours we notice that we don't really smell it around 6 ft away, so we opened it up a little bit more.We used then for a week but we barely notice the smell. Looking inside I noticed that there is just a very small amount left; only around 80% of the solid gel-like freshener is there. Not really happy with this purchase.
