I did find an update but it was asking for too many accessibility permission for me to be comfortable with so I did not install it. One bump and both of them are in the floor! one of them came loose after about 2 hours on the car. The fit was fine along with some growing room. And I did i am loving ? ?? ?? ?? ?? it! These toothbrushes work great and are good for the environment. Will continue to buy this brand and style. I ordered them in my usual size, 9. Now me and the hubby both wear Crocs and I don?t make fun of him anymore ?? I contacted the manufacturer and they sent me a manual, mind you, this was before the product was released, I was really impressed that they were willing to do that.
