Review on Accurate Micrometer Millimeter Conversion Measuring Tool for Household Use by Ken Martinez

Not impressed but luckily I only need it for a rough measurement. The caliper itself is pretty flimsy. If you just slide it, you'll feel it flex and twist. As you can see from the photo, mine also had a scratched screen. The packaging was perfect to the point that it was either broken or damaged in production. Not worth the hassle of sending it back but I would absolutely not recommend buying one unless you just want something very cheap that will fit most things other than precise measurements.
