The latest National Trust mag has an ad for something called an Ecocamel Jetstorm shower head. It claims to reduce your water and energy comsumption while giving you a good pressure "spa-like" shower, by sucking air into the water flow.
Reviews are very mixed, some rave about it, others are scathing.
The offer is a good price, with 30 day money-back guarantee (though you do lose the cost of P&P in both directions)
Anyone tried one? If so, what do you think of it?
