Mine is broken and already looking in a lot of shops, can't get them here in Brazil. I had the same one as you and also newer model. Newer model has simpler brushes, not the whole thing with a magnet. That magent alway got full of dirt and has to be cleaned. The new one hasn't that problem. I liked the newest better.. But mine works 2 years and than i need a new one.
I also think it is the best vibrator to travel, girls like the sonic vibrations

I should upgrade and use this one for .. travelling..
