Renuzit Adjustables Cones have always been an inexpensive way to make my bathrooms and home smell great! They last forever - they say 30 days but usually last longer. They cost about a $1.00 each, but the best new thing I just found - you can customize the outside of the cone with your own pictures! I don't have to hide them behind the toilet anymore so my bathroom will smell even fresher. <more fresh???>  Anyway, for those of you who love Renuzit Adjustable cones check out this site to make your own designs: www.stylemycone.com - it's free, plus there are some good coupon offers for Renuzit products....
