Torque Sticks--Anyone use these?

Great for a tire shop, not so great for an anal euro owner.

They are good to make sure you don't overtighten things, but I have found that if you go back with a real torque wrench, these aren't the most accurate things.

Went ahead and purchased the 90 ft/lb one and just wondering if anyone can comment on their usefulness?
