“First off, read the description, carefully. I was in a hurry, and thought I was getting 2 vs getting the 2nd generation. But, I'm still happy I got even one!! The allergies have been terrible, here in Fl this year, and we have been stuffed UP! On "my" Dr's advice, the first 2 days, I used it every 3 to 4 hours, and then 2 times a day after that. The difference was amazing. It didn't work straight out of the box. She told me, it's going to take some time, and it did! About 3 days before the stuff got hydrated enough to be able to get it out. But, It was worth the 3 days to be clearing up after months of this!”
