I bought this unit on the Amazon.co.uk website (cheaper) and it was delivered with a European 220v cord. Perfect. The device is very effective and gives a very pleasant feeling of clean teeth. If ca effectively replaces floss (we'll see next visit to the dentist) this is a great purchase. Only downside, the tank a bit tight. It allows for a complete wash, but if one wishes to take his time or a little time is to insist on a tooth, you must re-fill the tank.
