It is suitable for a wide variety of dry foods such as cereal, trail mix, candy, granola to nuts, beans, rice, etc. The unit's as-needed dispensing keeps food sanitary and germ-free, while its airtight seal helps prevent food from going stale and preserves freshness for up to 45 days, which means less food wasted. This food dispenser is ideal for parents as it promotes growing independence as children learn to serve themselves or for people living a healthy or weight conscious lifestyle. To use, simply place a bowl under the spout and twist the knob. The unit's portion-control system uses a soft, flexible paddle wheel that won't crush cereal, reduces messy spills, and dispenses a measured amount with each twist--about an ounce. Kids will enjoy turning the knob and watching cereal fall perfectly into their bowls, and parents can be assured that kids won't be spilling cereal all over the kitchen counter. Other highlights include durable scratch-resistant and shatterproof construction, a removable bottom tray for quick cleanup, and an easy-to-assemble design.
