Wireless intercom with two-way communication and the ability to connect up to 4 units. Purchased in June of this year and only opened once to confirm the contents. All accessories are included. I am selling it because my parent is entering a care facility. The exterior film on the stand for the intercom is still attached, so it's almost like new. When shipping, I will lightly clean it and wrap each accessory in plastic. Please refrain from purchasing if you have any concerns. Thank you. - Brand: ELPA - Model: WIP-5150SET - Features: Two-way communication, call function - Number of connectable units: Up to 4 - Rechargeable: Portable rechargeable type - Communication range: 100m Thank you for looking.
