Watch the 40-second breakdown.
The video runs 40 seconds. Here's the map.
The first half is monthly cost. The tall stack on the left is what you pay every month right now. It's five things stacked on top of each other. Each block is one bill. The bigger the block, the bigger the bill — they're not all the same size. The short dark bar beside it is TankSpotter. The red line across the stack shows where our price lands on that pile.
The second half is setup — the money you spend once, up front. It lists six setup costs. Then two bars: the long one is what all that adds up to, the short one is TankSpotter.
That's the whole argument. The tall stack is the bills you already pay, piled up. The short bar is the one bill that replaces them.
