Higher quality: unlike other sprinklers on the market, our trampoline sprinklers are made of thicker and more durable PE material that can withstand high water pressure. The hose is made of metal material and is more durable. It lasts well all summer and can be used repeatedly on hot days. Unique design: Our sprinkler is patented, can be rotated 360 degrees, and children can easily control the water pressure through the valve. This allows the trampoline water to be sprayed locally so that if the child feels too cold or does not want to spray water, they can jump or close the valve.
