Im going on a little over two weeks now I love it. It takes a little more work but i feel its well worth it I used to have two inches of feed on the ground around all the feeders and when you buy for as many birds as we do all the waste is costly. I buy 1000 lbs of bird feed every two weeks and from what people say the fermented feed gives them all the nutrients they need and results in not eating as much... In the past two days im finally starting to see a decrease in how much i have to put out each day... I swear by it i have no plans on going back to dry feed
