Query: Duro-Med Alternating Pressure Pump and Pad

Duro-Med Alternating Pressure Pump and Pad, GrayThis equipment is designed for 110V 60 Hz operation and as such is suitable only for use in North America.It would help if this information is promptly displayed as part of the product descriptions.I purchased the equipment without being aware of this and have difficulties making use of the equipment in Australia. However, Amazon has been a very fair trader and has refunded me in full. Full marks to Amazon.Ken kwongQueenslandAustralia
