I have lots of favourites depending on my mood, of recent times my suction toys, the InsideOut and the Melt are great but if I have to choose just one overall fabulous toy for me it still has to be my Mantric Rabbit.
So good it still takes pride of place in my profile picture, it feels like it was made to measure and fits me perfectly (though from reviews this seems a common feature). It is superb value, I think, for all it offers. To find out exactly why I think it is so great you can read my full review here
