Ex Input:
I bought this product on December 5, 2012. However, the battery died already in March 2013. In May 2013 it was hard to charge - sometimes you had to press and hold but by July after 10 uses (I was listening for about 2 hours per day average) It started acting up. The bluetooth stopped working so music sounded like the speaker is blown. So no matter how much I try to fix it, it's useless. Don't buy this!

Ex Output:
Bad review


Ex Input:
It is definitely a unique design. Unfortunately, it does not function well. You have to be very precise with your touch and you don't really feel the brush on my teeth at all. Not sure how else I can complain about something when it's still working perfectly after several months. One of the things that makes this toothbrush stand out is that there is no battery. With other batteries, they inevitably fail or die because they're always sitting around. This one doesn't.

Bad review

The headlight assemblies were easy to install, no problems there. However, on my 2004 Silverado 2500 HD both headlights now have intermittent blinking.
