I really liked this product!  I have been without dryer sheets for so long, I forgot how enjoyable a fabric freshner can be!  Although, I was a little skeptical about sticking attaching something to the inside of my dryer, I figure the adhesive can be scrubbed off if need be.  I think back to dryer sheet days, and I know that I would tend to forget to put the sheet in the dryer.  This product cuts out that step, since it just stays in the dryer.  I think it is a little on the expensive side.  I liked the scent too.  Haven't tried to replace it yet.
