Perfect continual communication every step of the way. The packaging came apart and I was fortunate the mini flashlight didn't fall out. 4mm more and it would have been lost. There wasn't enough tape on the self-made corrugated envelope. The flashlight works but the strobe does not. It's okay though, I just use it around the house and for looking at my electronics and firearm projects. This is the nicest seller I've ever had...honest!
