[EX Q]: I bought these to help with what I've read, to get the Jawbone to fit better. These ear pieces were hard to get into the ear no matter what size I tried. For a wireless earpiece you want to be able to get it on and off your ear quick if you need to, and these prevent you from doing so.
[EX A]: Negative

[EX Q]: This portable heater is good for use in your office, den or sleeping area..It is quiet and efficient,and is good for spot heating...please keep away from drapes or rugs,and small children,who might mistake this heater for a toy...Otherwise this is a good deal...Mine came with a remote to adjust setttings more easily...4 star rated...
[EX A]: Positive

[EX Q]: This movie is such a bizarre combination of morality and immorality it seems like no one would really like it, but there are always exceptions.If you're looking for a sweet Christmas tale, watch A Christmas Carol or The Grinch. If you're looking for potty humor, watch Beavis and Butthead. This movie tries to be both, and in the end, the sick humor and complete meanness just cancel out the moral message the plot tries to portray, leaving the viewer with nothing. Anyone who has the impression from these reviews that this is a "moral" movie, please beware, it is far, far, from it. There were glimmers of morality and good humor in there, but they were all but eclipsed by the nastiness.
[EX A]:
Negative
