I don't understand the purpose of spending so much money on certain toothbrushes, many people may disagree. These Up&Up ones are budget friendly. I feel good replacing them every few months, than replacing some other fancy toothbrush. Plus, they get the job done. I found I have 'cleaner' teeth, and better gums, than some of my friends and family who uses the fancier ones; we actually use to go to the same dentist and I was said to have the better teeth/gums.
