1st December 2012 I brought a electric toothbrush with four replaceable heads through Groupy. It was around $30.00 and my other toothbrush had broken. It took nearly 4 months to be delivered. When it was it was such a poorly designed toothbrush. Hardly any vibration. I have sent numerous emails to Groupy but have had no reply. I have wasted a lot of time and energy trying asking them to have a look at the product before the sell it. But have had no feedback. Disappointing. I terrible service.
