I'm afraid the assembly of this goal resulted in a critical problem - two parts broke. My son and his mother attempted to assemble the goal, unlike one other reviewer who didn't receive any instructions, with the aid of these - although the goal came in an unbranded plain brown cardboard box. Unfortunately two parts were assembled incorrectly and they managed to break trying to separate them.
The fault, I guess, largely rests with them but on inspection of the instructions there are some issues. In essence each part is labeled with a letter of the alphabet both on the part and in the instructions. All of these parts mirror each other on each half of the goal - so a `B' section forms the vertical upright pole on both the right and left sides of the goal. This is true except parts "F' and `G' which are exactly the same dimensions but are fitted in different positions on the right side of the goal compared to the left. Fitting these incorrectly caused the problem and the breakage. Giving these parts different letters would avoid the problem which is likely to occur if the instructions are not read in detail, something unlikely to happen with the eagerness to assemble the goal on delivery.
The goal is made of circular plastic tubing so is light and can be easily moved. Parts are in cases difficult to slot together, and even more difficult to get apart, so whilst the goal can be moved around the garden it's not really designed to be taken apart frequently. The lack of a carry case for the parts makes this clear despite the manufacturer's comment that it's designed to be taken apart. Reflecting the assembly problems, which reflect on the quality of the instructions, and perhaps the build quality, I can only give two stars. Moreover the design is very similar to an existing goal we have so I don't see much new here.
