When I brought in the mail, I was overcome but  such a strong smell and wondered what it was.  I found it was the Bounce Bar.  Wow...I was scared to use it in my dryer because I have scent sensitivity.  I would not be able to wear the clothes.  It doesn't smell badly, just strongly.  So, I am using it as an air freshener outside on my patio.  That works well and I do not have to smell it.  Oh well, if you do not like strong smells or strong scents on your clothes, do not use this in the dryer.
