They will blow over, the green rips and the frames buckle, however much re enforcing you do, and we put some stuff around the bottom, concrete strips, long metal poles etc, they will give way. All the stuff was still holding down to bottom edge, the top just folded up. Maybe you are in a sheltered spot then it will be ok, mine wasnt.
If you can get one to stay put, they are good, if you put 6ft. X 2" poles very deep in the ground on all four corners you can fix ropes to the top, or wrap a rope right round it then fix like guy ropes on a tent.
For around £30/40.00 they are probably woth a go, even if only for two years.
