I tried the other one to clear congestion, and this is just as potent, clears the sinus well.
In addition to the preventive component in the inhalant this works like a relaxant for the sinuses.  I am a BiPAP sleep machine user, and this and the other type I got work well before bed to keep my nose flowing freely before putting on my mask.  Like the other it was surprisingly potent and I winced a little the first time using, but it was never painful.  I do know painful by comparison, I have some super Wasabi (really a died green uber potent horse radish) that when I at for the first time too much in a ham sandwich, my nose and sinuses were burning for several seconds.  This is potent, but at least not that potent, and I prefer this to the Wasabi for opening the sinuses by far.  Nice inexpensive compact inhaler you can keep in your pocket for easy use when and about.  Recommended.
