I bought two of these alarm clocks for my sons' bedrooms. Like other reviews, these clocks do not keep accurate time in either room. The only purpose they serve at this point is to charge their cell phones overnight. This product is a waste of money and I highly discourage consumers to purchase it.

I really like Pippa's writing. This sci-fi slash fantasy combination has me hooked. Cannot wait til the third book is released. Plot keeps you guessing about what challenge will come next, and how will the character grow with it. Please keep this series coming...quickly preferred. ;-)
positive

I have purchased 4 of these, the claim to work for hot liquids however 3 of them cracked on the first use and fell apart. The plastic does not withstand drinkable coffee temps.. I’m not a huge hot freak, but these did not last.
