It amazed me it made that much of a difference! Probably didn't think intitally as my old ones seemed find though those were digital ones and the new ones are just cheapy non-digital ones. Unless there were out too, always seemed to correspond though so goodness knows! Mind you, the reason I figured they'd broken was because they were knocking a few stone off, even after changing the batteries...hmmm...unless carpet in that case too but they were fine before!
I'll have to stick them downstairs out the way somewhere!
