Main function: improvement of respiratory efficiency and lung capacity. Through regular training, the strength and endurance of the respiratory muscles can be effectively increased, thereby improving overall respiratory efficiency. Users will notice that their daily breathing becomes smoother; during sports activities such as running and swimming, breathing becomes less labored and lung capacity increases.

Widely applicable to a diverse group of people: · Sports enthusiasts: athletes and fitness fanatics use it to improve their sports performance and endurance, and to delay respiratory fatigue during intensive workouts. · General public: suitable for office workers who sit for long periods, smokers (who want to improve their respiratory function), as well as singers, wind instrument players, and others who require strong breathing control.

Design features: Breathing intensity can be regulated by means of an adjustable switch. The resistance is easy to adjust by opening the device and adding extra weights; this allows breathing power to be trained and lung capacity to be increased. The device is portable, lightweight, and compact, allowing it to be taken anywhere, regardless of location or environment.

Usage: This smart model with an electronic display features a built-in pressure sensor that automatically increments the counter with every correctly performed breathing exercise, eliminating the need for manual operation. By exercising for 10 minutes daily, users can start with low resistance and gradually increase the difficulty and duration of the workout as their fitness improves.

Activating the smart counter function: The device does not have physical buttons. Simply blow on it or shake the device to activate the digital display. It is equipped with an automatic shutdown function: if the device is not used for 2 minutes, it automatically switches itself off to conserve energy.

Troubleshooting: The screen does not light up or does not count. If the display does not light up or does not register breaths, check the following points: 1. Battery level: Ensure that the device is fully charged. The red charging light turns off once charging is complete. 2. Orientation of the weights: The weights must be placed with the dark side facing upwards. If they are placed upside down, the device will not function properly. 3. Minimum number of weights required: A minimum of 2 weights are needed to tap against the top cover during use. This ensures that the sensor is activated for an accurate count. 4. Automatic shut-off function: The device switches itself off automatically.
