Not to be disagreeable but, I disagree--LOL. I like the leds if for no other reason than troubleshooting. If the led is out, the battery is dead, if the led is lighting and I'm not getting a vape, it is the atty. If I ever wanted to stealth vape I can just turn the battery around in my mods then, no lights. Also, If you're not familiar with my mods, the led serves dual purpose--It can also be used as a flashlight for those late night bathroom trips or to land planes on remote landing strips--LOL
