Bests & Worsts Reviews from Amazon

I have been using this toothbrush since I purchased it in March. I don't travel much so I keep it at home in the charger most of the time. When I traveled the first time, I did not take the charger since it stated it should hold a charge for 5 days. When I reached my destination (several hours in a car) that evening the toothbrush power was dead. I just chalked it up to a "perhaps it went off in the bag and wore down the charge". The second time I traveled the same thing happened. I was so annoyed and wasn't sure if I had stored it next to something that would cause the charge to disperse. Now the third trip (this time I took charger with me), same thing. This stupid toothbrush will not hold a charge! I find that ridiculous. I bought two of these and my son's toothbrush is fine. Mine is clearly defective and now I can't return it because I didn't travel enough to "test" it. I read that others had the same problem so I'll have to research and see if P&G is offering replacements.
