Purchased as a replacement for a Braun one of similar price that had only lasted 8 months. I much prefer the Sonic Spinbrush. I hadn't noticed that it has a standard shape brush head and not a small circular one. It feels as if the larger head does a better job. It is called a spinbrush but as far as I can tell the centre moves back and forth. The brush is soft so I wonder how long it will last. Good value at £8.89 now £6.
