This 21 Gal Stainless Steel touchless trash can is designed and engineered by NINESTARS, the world's first legal patent holder. With its sleek rectangular fingerprint-resistant design, it can be used in almost any place, such as the home, office, kitchen, bedroom, dorm room or a kid's room. This durable trash can uses the most advanced sensor technology which can be found in all Ninestars trash cans. Pass your hand or debris within ten inches or a 130° angle from the infrared sensor and the lid will automatically open. The lid will remain open if debris or hand remains within the range of the infrared sensor. Three seconds after your hand moves away from the lid, it will close automatically. Power lasts up to 6 months in normal daily usage. It includes a ring liner to keep trash bag from public view for a neat and clean appearance.
