Great product. the upper ring that holds the netting is easy to break and does come apart easily. Every time I look out at this thing it has fallen off the poles that hold up the netting... The company has been excellent about replacement parts however, so no complaints here.. gave it 4/5 just bc of the faulty top but am happy with the customer service. 

Pros: Great Customer Service and good value for the money 
Cons: top rail could use some better engineering.
