Great travel toothbrush
Started with Sonicare years ago after periodontal surgery on advice of the periodontist.  The charging base of the original corded set was cumbersome for travel, and finding a charging outlet was problematic when camping.  This battery powered toothbrush solved the problem nicely.  My gums get the proper care, my teeth get cleaned, and the batteries last surprisingly long.  This is actually my second battery toothbrush from Sonicare.  I accidentally dropped the first one after several years of very satisfactory use, and broke the bottom piece that holds the batteries in place.  Unfixable, I simply bought a replacement.
