We asked the triallists to imagine they were about to buy a shower head and to rate how likely they’d be to purchase each model. We then repeated the question – after telling them the shower head would save $100 a year in hot-water bills.
- The Aquatica/Eco-Stream and Methven were the shower heads most likely to be purchased.
- The models most likely not to be purchased were the Flexispray Pulsar and Foreno.
- The other heads were somewhere in between.
