I tried this in lieu of my usual Biotene. It works just as well and you can't beat the price savings. I mouth breathe during sleep and this helps keep my mouth moist. Only thing I wish the cap were not a safety cap as I find it a bit difficult to open, so I transfer the contents to an old Biotene bottle. Yet I certainly understand the purpose of a safety cap. On my 2nd bottle of this now and if the price stays competitive this is my go-to rinse.
