Really surprised that there hasn't been more talk about the crown sf. Especially since so many people were complaining about the original one.
Got my Spire yesterday w/ crown sf and can't wait to try it out. But I will most likely buy some lithium AA for it since most post about problems is in regards to the Spire's preference for good batteries. They keep the voltage up longer, so the Spire should like that.
