Review on Accurately Measure String Tension with Tourna String Meter - Black (One Size) by Aaron Parish

Read the fine print first, nylon strings only. Second, the arrow pointing to the pounds of the string, the arrow showing the reading is a small sticker that doesn't stick very well. As I rotated the device in my hand to look at it, the sticker peeled off and stuck to my hand. I don't think there's a way to find out exactly where it's stuck. So I read the pamphlet that came with him and he started talking some nonsense about how the weight of the pounds could vary between what he was wearing and what he was reading, maybe ten pounds. So what's the point of having this thing if you can't get over ten pounds? Ridiculous. I would send it back but for 22€ it's not worth my time.
