Tonnelle very poor. The roof is smaller than 10 cm with respect to the frame which is also very fragile. We must therefore force to hold the roof up and suddenly the seams of the canvas tear. Besides the roof is already torn place before mounting! The seams tear at the slightest touch of the wind. This gives the impression that it is for single use and disposable as soon as you climb. If I could put no star, I would do! Never purchase this product! You will not be arbor but you'll save time and especially money.
