Query: Best system ever made. Are they no longer on the market?

I had a previous model where I had to apply the toothpaste. I liked the unit but hated applying the tooth paste. When this unit came out I purchased it immediately. There is no mess, no caps left off, and i am not looking for where I last put the tooth paste or brush. Also, never have to be concerned about a toothbrush laying on a dirty sink or counter and ugly hanging on a toothbrush holder.
