Now what I really want to talk about, and have discovered, fiddled with, experimented with over the course of 2 weeks and pretty much explored every option and researched every video out there, is the Odysseus. I'm currently looking for an Odysseus Base for the GGTS that I pre-ordered as well, so if any of you out there have one to sell please do drop me a pm. I'm lost for words with this product, it is just simply put, the most versatile rebuildable tank system out there. You can pretty much do anything you want with it, replacing the wicks and coils at pennies with the highest grade materials you could possibly get (as a vaper, you're inhaling this, so in my opinion, I'd want the best materials available). Anyways to carry on, if you like double wicking you can double wick, triple wicking, you can triple wick, tune it to ANY resistance you want and have it work the way you want, plain and simple, this product caters to your every need, and the best part? It's NEVER going to die, full stainless steel construction, very strong, very durable, the threading is fabulous and just top notch. Juice flow control, what can I say, this thing works, a pinch to the right or left could very well be the difference in your vaping experience, depending on how much power you vape at, the juice flow control system allows you to tune it in to that, and if you want close it all the way when you go to bed or leave it open, this thing never leaks, I've not had it leaked on my one whether leaving the juice flow control open or in any other situation where I've been experimenting with it. Again a more expensive product, but pays itself off in the long run, replacing wicks and coils for close to nothing, somewhere around the cost of 50 cents if you do your own coil, compared to buying a new atomizer or cartomizer which can cost anywhere from 2.50USD and upwards. Talk about dry burning, I dry burn this thing every 2 refills and on several occasions I've had the coil catch fire, and still there's nothing wrong with it. Unlike pre-built cartomizers and atomizers where I've shorted them out from over-doing the dry burning process I never have to worry about it with the Odysseus, the materials from wires to wicks can withstand up to (I don't remember the exact temperature) a ridiculous amount of temperature, so even when it caught on fire at the top nothing is damaged (I do maximum dry burns holding it for the full 16 seconds a Provari can do). So just wanted to put my opinions out there on the stuff that I've experimented with so far, this product is not a beginner product but it is something that I would recommend you get into when you feel that you're up for it.
