I do alot of laundry and did not expect the bar to last 4 months but did expect it to last long than 1 month and to pay over $5.00 that was a waste of money.   I stuck bar to the wall of the dryer   After a few times, it fell off and broke up in my dryer leaving behind a lot of pieces to pick up. I, also, had to clean the sticky residue from the dryer where it was stuck.
