Ian your right as a part of an overall message it might be useful, but I'm seeing more & more companies using it as a the sole reason to chose them,
how many websites & leaflets have i seen with loads of info on why they are Eco-friendly, but none of them mention how using turbo dryers can have suites ready to use in 30minutes or carpet ready within 90minutes, which to the customers is a bigger selling point.
all I'm saying is don't lose sight of what's really important to the customers, of course mention it, but don't make it the meat & potatoes of your message
