I have tried various wine aerators before and i have to say this one is one of the best. It is packaged real nicely that it makes you want to put it on display for everyone to see. When I used it for the first time there was no issues for the wine flows through it as expected and gives it a great refreshing taste to which wine should have to it. I even did a test of before with no aerator and one after using it. I have to say the after is best. I love the bag it comes in to to protect it from scratches etc. I highly recommend this to my wine lovers and best part I can take it on trips too.
