About 4 hours for one person to assemble. Positives: Looks great, the LED lighting is a nice touch and the fire works as advertised. Negatives: I used clear packing tape to support the LED wiring. When viewed from any angle other than dead centre the holes for wiring are an eyesore, I cut the bottom off two yoghurt containers to fill the holes. Given the cost of this item, surely a pair of white silicon disks with slots for wires could be included?
