This model only gets 3 stars because of the stupid product barcode sticker. At first glance the ruler is fine, but I ended up having to either squeeze or erase the cork to remove the sticker. I suspect they didn't put a sticker on the stainless steel side as the numbers and ticks are just painted on and will likely rub off, especially if some sort of solvent is used to remove the d*#m sticker.
