Yup hairy ..you`re right of course..... that`s what I get for logging-in just after getting out of bed !!! Was only onto my first cup of coffee as I was typing ..lol. Yeah I didn`t look properly so missed the dot/point before the `5` and read it as 5-ozs instead of 0.5 ozs ..... so your calculation is correct, which makes the price quite ok really..... the `Tracksafe` is not too dear so...... anyway, if Xeon wants to try it, I`ll happily pop a sample in the post and he can give us his verdict....
