this review title is: do not get it and the content is: i was disappointed in this because it did not seem to be much different from the regular nozzle i use all the time i even turned the water all the way up and it did not blow the nozzle off as predicted since i have been getting rave reviews at the dentist i think i will just stick with the regular nozzle so much easier than having to switch refill switch back for the next time actually i can keep them for replacements if when my regular ones wear out if they ever do.there are other information for this review, one is this reviewer did purchase it and the other is 1 people think this review is helpful.
