Review on Effortless Cleaning with Evursua No Mess Bird Cage Feeders: Automatic Parrot Seed Tube for Easy Bird Feeding & Cage Maintenance – Perfect Accessories for Parakeets, Canaries, Cockatiels, Finches & More! Install Freely, No Fragile Parts! by Danielle Mitchell

I bought this for my finches a few months ago and it works as described. What I like best is the lack of junk. Anyone who owns birds knows how much seed they waste, and this appears to be seriously reducing that number. It's not 100% trouble-free, but it's not when it comes to birds. Remember to empty the bottom tray before it gets full. Once full it will drop hulls everywhere when you pull it out. This was a trial period for me and I am so pleased with this product that I intend to purchase it for my other cells.
