Review on Accurate Micrometer Millimeter Conversion Measuring Tool for Household Use by Justin Santiago

Can't comment on accuracy because every time I tried to use it the battery compartment would open and the battery would pop out. In the end, when trying to measure the inside diameter of the drain pipe, the battery hatch opened (as usual) and the battery popped out and went into the sewer. I got so fed up with this happening all the time that I just threw it away and now I'm looking for a better quality digital caliper that doesn't open the battery compartment and the battery falls out every time I try to use it. Save yourself a major headache with this cheap junk and don't buy it.
