Works very nicely for the price!
Not much to say-it works well when used properly (if it stops from too much pressure-your using too much pressure).  I used it on my kid's teeth (4/6/7). The older 2....took the yellow off...and polished all our teeth!  Really works well-I understand the cheap price-it is cheaply made...but well made and does what it is meant to do!!!  Definitely say get it if your goal is for polished teeth :)
