I’m not holding out too much hope. They haven’t been available for a few years now. However, the Soladey-3 is almost identical, except the handle is a tad thinner. The other differences was that the Ion5 had a soft head already mounted and an extra soft head in the packet with a little head protection case. Of course this meant the Ion5 was more expensive. The Soladey-3 is mounted with a medium head. The inner workings of both of these toothbrushes are the same.
