We got in 3 of these and decided to keep one and all I can say is this thing is the best one yet!! We get alerts when a bird lands to eat and the best thing is that it will scare off the squirrels when it detects them instead of a bird. The best thing is, is when the hummingbirds come around. You really get to be up and personal with them. The box was opened and that is it. It has never been put together and has never had any food in it. I know you will love it If you love your birds.
