I like this simple product very much
I like this simple product very much, and I use it everyday since I bought it.  it's very efficient.  my one complain is the tube.  I hope the factory can supply an extra tube in the package.  the tube can't handle hot or warm water.  the end of the tube broke twice with warm water, and I cut it short.  luckily my teeth can handle cold water, most people can not.
