milder more pleasant taste than biotene [SEP] i somewhat prefer the act spray to the biotene spray because it has a milder flavor i never much cared for the taste of biotene however both products seem to work equally well in providing short term relief of dry mouth symptoms another advantage of act spray apart from the taste is that it comes in a flat container that can go in your pants pocket or shirt pocket without creating too unsightly a bulge be aware though that the biotene container holds one and a half ounces compared to only an ounce of act i have not done the math but i think you pay more per ounce when you choose act that flat container that i praised also has some disadvantages the flip top lid can get in the way when you try to spray and the spray nozzle button on mine tends to rotate too freely when i am using it so you take the bad with the good
