Wish it worked for me!
Very good idea for a product and I wish it could have worked for me but I need something stronger for my panic attacks.<br />Plus I did not realize that it only last 500 breaths and it did not come with any extra filer packets so I am assuming after 500 breaths you just throw it away.  It is too expensive to be disposable.  I will be returning unfortunately.
