Thank you much. This helped a lot. It sure looks like you had good times with your toothbrush lol.

I have an almost equal one.

Questions:

How do you managed to get it so clean? Mine is 1 year old and no matter my efforts to keep it clean, the rubber parts are turning black;

Is yours powered by AA batteries? how you managed to not break the lid that holds the batteries together? I have to put some strength when I replace batteries so the lid actually closes and I don't get flying batteries while I am brushing.

Apart from all of that, love it.
