I dont have any and never will - I've seen the frustration it causes - both here and in person.
Last night a lady who joined last week and bought a 12 week countdown said she didnt know whether to come this week as she hadnt lost anything.
She'd been on and off the scales several times a day and by her reckoning hadnt lost a single lb - in fact she thought she may have gained.
She lost 2lbs.
But had a miserable week inbetween, and very nearly threw away £50 worth of countdown thinking there was no point.
Absolutely not worth it.
I've been known to lose 3lbs in as many minutes simply by dragging my wii fit board 6 inches across the floor. Luckily I know not to take the slightest bit of notice of it.
