That Price is definitely only for the Mod!!! The Batteries (and Chargers) in most Kits are too cheap for most USA Vendors to carry - too many problems with the Batteries, and the Chargers are extremely Cheap (like $5 Retail, Cheap). And I wouldn't want that KSD brand. IMO, $58 is way too much for the KSD, and $40 is too much for finished Copper/Brass/Whatever. You can get a Stainless Steel Vamo V3 from Discount Vapers for $50, when they're In Stock, or ~$57 from MVS.
According to Discount Vapers, the "Internals" are the same, only the AVG Function is gone now. It's only RMS now.
This is somewhat true. There is also a Stainless Steel model now as well. But it does come with two tubes now.
Personally, I don't find that new look all that bad. Do I wish they hadn't changed it? YES! But I think it will help with the Grip. I didn't want a V2 over the LED Screen. But my question is, if it's more Efficient, etc., with stacked 18350's, I wonder of there's a way to stack 18650's. I know it would be as long as a Police Night Stick, and probably just as deadly, but I'd like to know of an additional battery tube can be added to accommodate stacked 18650's. I'm a pretty heavy vaper, and I have 4 brand new Panasonic 2250 mAh IMR Hybrids, but Zero 18350's as yet.
