This unit handled a deployment in May 2008 and is still operational in September 2011
I purchased this sonicare unit in May 2008 when I deployed to Afghanistan.  I decided to take this item over my regular sonicare foreseeing the problems with electrical current and I didn't want to destroy a $60-75 unit.  I paid about $28 for this item.  I placed this item in a regular ziplock bag in my ruck sack and used it every night with no issues.  It probably got banged it quite a bit.  I changed batteries no more than 3x.  It served me well.  I always wiped it dry and stored it in a the ziplock bag.  The bottom did chip and it made it difficult to remove the bottom to replace the batteries but that was the only issue. I have noticed that the inside case is starting to rust but it is still operational and still going with no issues.  I will definitely buy again...3 years + and still running.<br /><br />Update - March 2012 - Unit is still going strong.  Use it everyday, change the batteries about every 60 days.  Best Sonicare, I've ever owned.<br /><br />Update - July 2013 and still using it everyday!<br /><br />Update - July 2017, the handle finally died.
