I'm sorry, but I just cannot believe so many people are still messing around with these little plastic carts, the sapphires or kisses or whatever. Maybe it's just a location/availability thing... The kanger evod2 glass tank works excellently for oils, it's Pyrex and metal and the wicks and coils are replaceable. I've used the little plastic things y'all are referring to, o-pens, most of the aspire and kanger tanks and different mods, different pre-loaded carts from dispensaries, the evod tank works best and actually looks normal on a battery! I know function is important, I just find it hard to believe no one has lost their mind over the way those sapphire carts look on a battery. I mean, come on! And they're almost entirely plastic...I'm a little surprised, I guess, that such an aesthetically displeasing design is still being tolerated. I know they work, but so do 4 or 5 other carts that look entirely normal on a battery.
Another aside from the evod is the ipuff. It's an elliptical battery, and the 3-in1 do flower oil and wax, but it has a refillable cart that is made specifically for oil, and it works very very well. I bought the battery for $15 and a cart loaded with a gram of 78+%thc oil for $40, lasts me about a week, I pick up oil and refill the cart. The oil is thick but the cart does a good job of warming it up, it's made specifically for oil, work great. On ebay I found a 4-in1 by Dry Vapes for about $20.
For wax and shatter, please stop liquefying them or tearing your pro tanks apart to expose the coils. The atomizer to buy is the seego vhit type b atomizer, get the one with DUAL COILS. It comes with a metal dual coil cup that has a cap, the cap catches all splatter and returns to the coils. You can get these on eBay for about 15 bucks. You could also buy what is called an "un breakable tube" on eBay, to replace the glass piece, and you would be set. I've had one working for about 2 years now, I just order replacement cups every once in a while. Looks like a normal ecig, I use it everywhere without attention. The seego vhit "rise" atomizer is a nice one too, but I prefer the vhit type b personally. They work fine with oil too, you just have to load it up a couple hits at a time.
Look, I know those sapphire carts have lots of supporters...I guess because they usually work. Just wanted to offer an alternative, something that always works and actually looks good, too. And no reason to liquidize your concentrates to put in tank and use with a pen. I guess that's why people are taking perfectly good concentrates and liquefying them, I have done it...but in my case it was for vacation and convenience...but generally, I use my tiny vaporizer atty on my ecig battery, it works great for everything. From someone who has used the sapphire carts too, just sayin, there ARE other! better options.
What sets the Evod apart from every other bottom coil wicked atty?
