After twelve hours, the red light was still blinking and the battery still would not charge. I returned this defective battery for a full refund and bought another brand which works perfectly.

input with options: Title: The worst phone that I had ever bought Review: The phone is slow, and the keybooard is too responsive. Sometimes I press one number and it is dialed twice. When I answer calls usually they are put on hold. I wont buy any other sony ericsson product ever. At least mobile phones. Also, sometimes the home charger does not charge my mobile. It is really bad. Is this product review negative?

input with options: Title: Could Have Been Better Review: There's some good material in here, more appealing possibly to the causal aviation enthusiast than a real aviation enthusiast. A tour de force in stretching a small amount of aircraft footage into a feature length DVD - don't expect extended sequences of ground or aerial manoeuvres. Frequent interjections by the narrator talking over nothing more that a title page for tens of seconds gives the impression of padding the material out, and I think this would be a correct view since there is precious little information imparted in these padding sequences. The 'which is the best' trump card approach really wouldn't I believe appeal to a true aviation enthusiast - which is the best fighter aircraft for example exercises a rather purile discussion - if you're really into aircraft this DVD set is gloss with no substance.
