※ Purchased on Mercari in April 2023. I have not used it since purchasing it. ※ The main unit is new and unused. ※ There was one D-pad missing from the start, so there are only 4 pads instead of the 5 that should be included. ※ Regarding the gel to apply to the sensor, the expiration date is not indicated, and although I haven't opened it, it's been over 2 years. Please use it at your own risk. I will include it as is. ※ Although it's been 2 years, it's unknown when the previous seller purchased it. ※ Operation has not been confirmed, so it is being sold as a junk item. Everything in the photos is included. 【From the website】 Dfree is a device that uses a sensor to detect bladder fullness and notifies you of the timing of urination via an app. 【Addresses various urination concerns】 Supports concerns such as frequent urination and anxiety about going out, wanting to use it for toilet assistance, wanting to use it for children's toilet training, and wanting to visualize the urge to urinate. 【Various usage scenarios】 Wanting other measures while using diapers or urine pads, wanting to make toilet guidance in caregiving easier, wanting to prevent bedwetting in children, usable in various scenarios. 【Ultrasound measures bladder fullness】 Uses the same ultrasound as an ultrasound examination to capture changes in the bladder.

Please understand. ※ I have a child with severe physical disabilities at home. Due to the season, they are prone to illness and may require hospitalization. Therefore, it may take some time to ship. Please consider this if you are okay with that! ※ I am raising 6 children, and shipping will only be on weekdays. I am sorry, but I cannot ship on weekends and holidays. I will be taking a break. I will ship within 4-7 days from the following week. I will contact you if there is a delay. I will strive for a pleasant transaction. Thank you for your consideration. Thank you for viewing.
