This is our second machine of this type and it became necessary to renew after 2 years of dedicated multi-daily services of the first device. Easy to use, more adjustable jet powers, several different nozzles with or without a brush to get anywhere in the mouth. One is sometimes surprised to eliminate residues that would not have imagined present between teeth, certainly subject to local degradation and then sources of infections. A must for us that wants to maintain good health!
