This water table is big hit with my 2 and 5 year olds. They love being able to stand in it and splash around. Especially love using a toy bucket and watering can to transfer water to the waterfall areas. Was easy enough for me (mom) to build on my own. There are no pre-drilled holes but with my own wimpy arms I was able to screw all of the screws in to the plastic pieces where instructed. The palm of my hand was a little sore the next day. Once built, it is still lightweight enough that I can easily lift and drain it each day and carry it into the garage to store overnight. *do make sure to read the very simple instructions on primping the pump before each use- simply pour some water down the top of the pump and make sure the bottom of the spout is covered with at least an inch of water*
