I deposited $5000.00 with Fujian Baotong Electronics Co Ltd. In return, they shipped 20 faulty and non-functioning/faulty long-range cordless phones and broken battery chargers. I have since learned that the Baotong Senao phones use old technology and are poorly reverse-engineered copies of a product manufactured in Taiwan. The BT-H258PLUS LCD- Cordless Phone Handset is a knock off. Do not confuse it with the original Senao products from Taiwan.
