Simple to put together. The only complaint are the suction cups aren't that strong so sometimes they slip off but other then that this is a great product!
The actual design is pretty good; the seed stays dry, even in our sideways Florida rain. However, mine arrived with a bunch of hairline cracks, hence the 3-star rating.
This is a really neat item and I love the concept. We have a little one in our house and I love that we can watch birds eat from our window super up close. The feeder has two compartments on ours so you could do two different types of food if you wanted to attract a wider variety of birds. I love this! I had read other reviews about it falling off but also read a trick about adding olive oil (I'm sure others work too) to the suction cups to get it to stick. I did that with ours and it hasn't fallen yet. I took off two stars because ours came scratched/cracked at the top and I was too lazy to return for a different one. It still works fine and it doesn't seem to be affecting the structure/sturdiness of the item. Overall we would highly recommend.
This product is heavy duty plastic. BUT....the plastic was defective. All along the front edge of the roof is defective. See photo. It was a gift for my Father.
