I really enjoy this product and it does exactly what it describes. I use it on my balcony. It is effective, but still very lightweight. It is easy to assemble as well. The price point is excellent. Also, I had an interaction with the company about an issue and they were incredibly responsive and helpful, fixing the issue immediately. Highly recommend.
