PRESENTER: Good evening.Tonight's show comes to you from the Good Home Exhibition in Duke's Court,where we've been trying out some of the latest gadgets on show here and getting our resident expert - Liz Shearer - to tell us which ones are worth buying and which will die a death.

LIZ SHEARER: Well,hello.Yes,John,I've been investigating four new household gadgets and sorting out the advantages and disadvantages and then really deciding what are 'Must buys',what are 'Maybe buys' and what are 'Never buys'.Let's start with this vacuum flask for keeping drinks hot.Well...I felt this had quite a lot going for it,most of all is the fact that it contains no glass and is therefore unbreakable to all intents and purposes.It's made of stainless steel which is guaranteed for 20 years...hope that's long enough...and it's true what the manufacturer claims - that it does maintain heat for 18 hours.So that's pretty good.
