I have 4 of them -- still working since 2010
These are great toothbrushes but many people seem to be having reliability issues.  Not me, though.  I bought 4 of these in 2010 for my family.  All of them are still working and I have replacement heads delivered regularly via Amazon's &#34;Subscribe & Save&#34; program.  Great!  We use them with rechargeable batteries; they last almost a month between charges.<br /><br />But let me repeat what others have said: you simply have to LAY THEM DOWN TO DRY.  Don't stand them up on the base.  I had read that advice in the reviews when I bought them.  My kids and I quickly got used to laying them down after use.  However, my wife really had trouble learning this and she kept leaving it upright.  Her toothbrush would occasionally stop working so I would open it up and let it dry thoroughly and it would start working again (although there is some corrosion inside.)  She finally learned to lay it down, though.<br /><br />Highly recommended (unless you are unwilling to slightly modify your behavior for a bargain!)
