Excellent. We saw this super soaker on the Gadget Show and decided to purchase them for our boys (7, 5 & 3), they absolutely love them and have no problem using them a little heavy for the 3 year old but he managed quite well needing a little help with the water pump. Plenty of water in the gun that you don't feel as though you are constantly filling it up. Only problem is we now need to buy more for us parents. Bought at have half price.
