Alrighty, well I've had my Sig+ for almost 48 hours now and used it almost exclusively all weekend. I did vape on one of my mechs briefly while waiting for batteries to come off of the charger but the Sig has pretty much been in my hand since it's arrival. This is one seriously nice box. At first I thought that I'd mainly use it at home but forget that! I deliver pizza part time and worked a nine hour shift on Sunday. The Sig came with me and I used it all day at 40 to 50 watts, and the batteries lasted me all day and then some. It's also with me at my main job today and while I do love my mechs and iStick, my Sigelei is my new flagship mod. It's already the first one I reach for. I'm currently vaping "Fruit Rings" from Everyday Drips (6mg) in my MXv1, 22 gauge, .3 ohms, at 40 watts, and it's beautiful. I have no more vape itches to scratch. Endgame achieved!
On question though. When do you pull the batteries for charging? I find that when the battery meter reads 50%, the battery voltage is about 3.5v, so that's when I put new batteries in. But it does take alllll day to go from 100% to 50%.
Sorry if I'm a bit rambly. I'm just really, really pleased with this purchase!
