For those who don't have or want 240 volts. We each have an Oral-B 2 x AA battery toothbrush (bar code 4210201822233) It is not as good as a 240 volt one, but it's about all I have found that is reasonable. Batteries last for weeks but we are using rechargeable & have a 12 volt AA charger. When cleaning teeth it feels like your 240 volt rechargeable toothbrush is somewhat flat but it's not too bad. It feels solid & well made with a good weight in the hand. Considering it has the same rotating action as the 240 toothbrush we both think it is pretty good. It does not have any of the fancy pressure functions etc, but it has the same basic rotating action just a bit slower.

At about $25.00 we think it is worth buying if you like an electric toothbrush but don't use 240 volts while traveling. Going overseas it will save mucking around with mains adapters & take up less room, just buy some AA batteries locally if you run flat. It comes with 2 x AA batteries which work well, & 1 brush, so pretty good value.
