Product review (1 stars): Some good, some not
I'm not sure why this item shows that it is in stock and ship immediately, and then takes 2 weeks to ship even with Prime.  That's besides the point though.  I bought 3 of these twin packs.  2 out of the 6 are not usable.  The liquid inside is disconnected and nothing corrects it.  Swinging it in my hand from shoulder down to side multiple times as the instructions mentioned did nothing.  I even taped these to a fan blade in an attempt to centrifuge them.. no help.  Warming the bulb up.. no help. These 2 are worthless. The other 4 seem ok.
