A year after purchasing..
... and I'm still using it.  When I bought it here on amazon, like others I didn't get the right item, and it didn't come with the tongue freshener and the interdental cleaner.  I complained to amazon, who then told me to take my complaint to the manufacturer.  well, I did and they gave me 3 different complimentary brush heads.  They also told me that they don't carry the tongue freshener anymore.  Oh well, I have a regular tongue cleaner anyway.  The 2 minute timer is pretty nice even though I don't pay attention to it at all.  The pressure censor doesn't seem to work because no matter how hard I press, nothing happens.  The battery life is great, still works like I just bought it... I only have to charge it once every 2-3 weeks.  Overall, I'm still very happy for purchasing this product.
