Firstly, let me say that the Kiztoys water guns are basic. This is by no means a bad thing though. It means that absolutely anyone can use them - you just need the strength to pump the handle. There is a handy, large outlet hole which makes them so simple and quick to fill. Kids could do this easily. The water pistols are a generous size and give off a good jet of water that reaches a decent range. Most of all, they are just great fun. They will while away any hot, summer day & I'm sure they will get a lot of use.
The listing on Amazon also says you can use them with ice cubes for an icy blast, or even fill them with coloured water & make washable graffitti art. I haven't tried this yet, but it's a nice idea and it's something we will do. They seem good value for 2 large guns, and they are exactly what I was expecting - good fun!
