I purchased 2 of these lights and was surprised at how bright they are. Very convenient for places you can't or don't want to run hardwired electricity. They would also be great for a camping trip. I will definitely be buying more.

Ex Output:
positive


Ex Input:
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.

Ex Output:
negative


Ex Input:
This door knob set was just what I needed for my remodeled bathroom. It looks nice, was easy to install. Now my wife wants to change the Door knob sets in all the bedrooms.

Ex Output:

positive
