I bought it about four or five weeks ago and have been very impressed, too.
I did stop using it for about ten days because I had a cold, but have since
resumed.  I find it very soothing and it seems to be leaving my sinuses
clearer
then they were.  I also had trouble because antihistimines with
decongestants
dry out my nasal tissue, and w/o the decongestants leave them feeling wet.
The Sinofresh leaves them feeling just naturally moist - the way they should
feel.
Usually things like this don't work for me, but I tried it on the
recommendation of a
friend and while I know it won't work for everyone, this is working well for
me.
