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.<br /><br />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.<br /><br />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.<br /><br />*or more likely because it was upside down.
