I've heard that, too, and it's really put me off them. :/
I do wonder if maybe there was a defect of if they've corrected it but I'd want something solid to go on before investing that much in something that could have really gross issues.
I hear these toys are really difficult to clean :/
It isn't very difficult to clean but, you do need to pay a little more attention to the this one as opposed to a toy that is a solid silicone toy. I described a seam between the metallic looking plastic and the silicone in my review. I just like to inspect that seem to make sure it is clean on a regular basis. Otherwise all you need is some soap and running water to clean this toy.
