The DryBuddy Magnetic Sensor and cable attaches to standard cotton briefs to sense wetness (urine). The patented magnetic sensor is designed to attach firmly to briefs with great ease and comfort. It has no moving parts. The briefs do not get folded or clipped. This makes it extremely easy to use, even in the dark. Very convenient to use and clean. With no moving parts and all surfaces completely exposed, the magnetic sensor is extremely easy to clean and dry. Wash with soft soap and warm water. Dry with soft cloth. No digging into nooks and covered spaces for cleaning or drying. Very easy to attach. The cotton briefs are clamped between the two sets of magnets. The briefs do not get folded or clipped. This makes it extremely easy to use the sensor, even in the dark. No supplies are needed. No tapes, pads or other gizmos to waste your time and money.
