Review (5/5): how to prevent leakage
i've had this toothbrush for about 4 months now and it still looks brand new. i just checked inside the battery compartment and it's perfect; i've never seen a drop of water inside it any time i've checked. inside where the brush screws on, it looks brand new also. there was a drop or two of water up in the brush shaft, but i think it had been prevented from dripping into the base by a seal*. the base shows no signs of water at all. i had the first version of sonicare toothbrushes that stood vertically on the recharging base and those always had water dripping down into the inside. what's the difference? i read so many reviews of water leaking into the base and the battery compartment i decided to store it vertically, but upside down. that's right: UPSIDE DOWN.
honestly, some of the negative reviews i read had me so scared, i've been pretty obsessive with it. after i brush my teeth, i rinse it well but only to about an inch above the logo. i certainly don't submerge the whole thing. then i vigorously shake off the excess water. then i wipe the outside of the toothbrush with a towel. then i stick it upside down in a toothbrush slot until next use. did i mention i was obsessive? well, anyway, it works like a charm and it's still in perfect condition.
also, i have not used any of the newest models of sonicare, but i'd rate this one as slightly better than the original model, which had a guard around the brush that got in the way. sonicare is the best performing toothbrush i've ever owned by a landslide.
*or more likely because it was upside down.
