Review (5/5): works
Have tried other square activated carbon packs - less expensive, but simply do not "stop the smell" -- these work very well, and so far I just cannot find that they ever cease working - multiple uses, have even gone thru washing-machine by mistake and continue to absorb smells. I have been using my first three-pack order for over three months now.... Since they last SO long, I suggest you also order a pack of the extra stick-on double-sided tape from same supplier, which can be applied atop old tape when it loses its stickiness after about a week's ripping off undies to re-use. (comes with a few extra tape-strips, but the pads outlast the supplied tape)
