My kids were very excited to about this water gun. It has a huge reservoir, but it fills up quickly in our pool and is easy to operate. My kids enjoy playing both in the water and around our property and their water guns have a decent amount of fill so they dont need to refill as often as our old water guns. Overall we are pleased with this and other water guns we own from Kiztoys and would highly recommend them to anyone wanting to have some FUN.
