The assembly instructions are a tad vague, especially when it comes to the nuts and bolts sizes required.
The upright peice of metal that holds the food grill is made of very flimsey metal (almost to the point that anything heavier than a sausage starts the whole BBQ to bend!).
Aligning the grill holder (mentioned above) with the screw holes round the base unit took me a total of 35 minutes and 6 screwing and unscrewing of nuts/bolts.
A simple 'alignment' mark would erase this.
Total assembly time took over 1 hour due to the above - be warned!
