Totall bummer i havent posted on this thread in 8 months or so, but my ego Tank attys only were good 2 me at the beggining<maybe 2 months>, and havent had any success in cleaning or maintaning them at all, kinda feel like i got jipped cust I have 510 regular attys that are workin fine over a year later<some even with no major maintenance> But cuz of my experience with the cone shaped eGo style attys I havent bought any more thinking I would be wasting money, but i have found a solution and I suggest any1 look it up. "The Pumpcart solution" by Gotvapes, like dripping but not having to have a bottle of juice everywhere u go, and the "Pumpcart solution" as they call it, works IMO 100 times better than any tank system out there, just like dripping, and they offer a "bridgless atty" to come with the pump carts and its a 510 that rocked my world!!!!!! BIG SHOUT 2 GOTVAPES.COM FOR THIER VISION OF THE BEST VAPING SOLUTIONS AND IMPECABLE CUSTOMER SERVICE, PEACE!
