Love this product, does what it says and really works.  I have one in the bathroom and in the kitchen.  This thing absorbs any odors and leaves the room odor free.  Just put in the sun for refresher if you find that it is not working to its full capacity, but so far haven't had to do that.  I have tried powders and sprays, but this thing does a great job.  I bought one for my teenage nieces car, you just purchased her first used car.  Well the original driver must have been a smoker, and she tired everything to get the smell out.  Fresheners, sprays, powders, you name it and everything failed accept for this.  It worked great, so much I purchased more.
