100% in agreement with the OP! As a matter of fact, thanks for this thread, which motivated me to go through my collection to make sure there were no vampire drained cells. Unfortunately, I found some.
Ideally, I prefer a hard on/off switch in combination with an e-switch for adjusting the mode, but those are pretty hard to come by. I think I have two in my entire collection with that setup. I wonder if there are any enthusiast flashlight forums out there that could incorporate the dual-switch setup into a cool new flashlight model…
