|To the point|
And she's right. It gets straight to the point and gives you the product benefit right there. It "Stops Smelly Sinks."
I think this is great marketing. If I had a smelly sink I would want a product to stop that. Seeing it made me wonder if we had a smelly sink. I was in the supermarket. I couldn't go and sniff the sink to check. I was tempted to buy it just in case. Maybe I could use it to make sure my sink didn't become smelly.
The first rule in marketing is tell people about the benefits, not the features. I don't want to know what it's made from, or what the active ingredients are, I want to know what it does or, more importantly, what it will do for me. This marketing puts the benefit front and central. I know if I use this it will stop my sink from smelling. It's clean and efficient marketing copy and I think it's great. Well done, Buster.
(I mean, I didn't buy it. But if I have to sort out a smelly sink in the future, then I probably will.)
