I have no idea if other reviews are accurate as far as measurements go, but for my use case I just need consistency. I'm tired of using the paper sheet flattening technique as the paper shrinks and isn't as even. Using a 0.05mm gauge provided a near perfect match to the base instantly and without much fuss. Just twist until the sensor slides freely. -1 star for tool oil, which you absolutely must remove because if it gets on your bed, it's very bad. I would prefer something that doesn't require rust preventive oil as other reviews mention rust if you remove the oil completely.
