This is by far the best tank to date I have ever used! And I have about 25-30 tanks in my drawer....I coiled and wicked it with a lot of skepticism about leaking....after watching a vid ..I still was not sold....my other half purchased this because it looked cool.. ...but I do the building... this tank is amazing...Flavor is spot on....since I am a dripper exclusively ...my tanks are still in their boxes..The flavor and vapor are amazing! And NO LEAKING.....Not saying it won't ever leak...but it will be user error if it does...Top fill is perfect! Build deck is easy to build on ... . If you haven't tried it ...buy it....even if you're a dripper, you will love it! Eciggity kudos to your faster shipping, I was amazed at how fast I received my last two purchases!
