This one works on overseas voltage....others don't,
Amazon Verified Purchase(What is this?)
This review is from: Braun Oral-B Triumph 4000 Four-Mode Power Toothbrush (Personal Care)
No doubt you've read the other multiple reviews on here telling you how good this brushes so I won't repeat that.
However, it is worth you knowing that this model is dual voltage (110-220v) which means you can charge it overseas e.g. USA. However, Oral-B have been cost saving and their newer basic cheaper versions are no longer dual voltage which means they are useless when you take them on holiday with you. Make sure you read the manual before packing for your holidays otherwise you'll be left toothbrush-less on your trip after a couple of days use.
