LIZ SHEARER: On the down side,it really works outto be quite expensive and,much more surprisingly,itunfortunately leaves a strange taste...you knowwhen you've drunk from it...so all in all,myrecommendation would be it's got plenty ofadvantages,but it is rather expensive so I'd say youshould maybe buy it.
Moving on to a natty little device...the Whistle KeyHolder.Basically this is where you whistle and thekey holder gives off a high pitched noise and flasheslight so you can find it.One advantage of this modelis that it also has a small light.You press the button and this means you can find keyholeseasily.I also felt the small size was a real advantage.On the weaker side,I did find the noiseunpleasant.Which I'm sure the designers could have done something about.And I found that itdidn't work through metal,so it's mainly useful for finding in coat pockets,cushions,etc.Buttaken as a whole I thought it was a masterpiece of design and would highly recommend it.
