Tobeco Big Dripper RTA
One of the first RDTA (Rebuildable Dripping Tank Atomizer) devices to hit the market, The Big Dripper is built just like a regular atty but it has a 5ml tank that sits on top. It also has an Auto Dripper or Push Activated Dripping function, so when you are ready to drip, you just press down on the drip tip and it will automatically drip 3 drops of juice on the exact spot on your coil/wick.
I thought for sure this product would change the market and while it is great and innovative it needs improvement. I do enjoy it and used it quite a bit. If you are comfortable building then you will have no problem finding a build that works well on this atty.
