In general it is very good product.
Just three things might be improved.
1. Should add leave gard net on the top of each pole, otherwise the leaf will go into the pole with raining water.
2. I have trouble to screw hard top roof, since screw is not long enough. Should make screw 4mm longer.
3. I installed by myself 99%. But still need my wife to help hold screw in side. I go outside. Should make it done by one person.
Thanks
