Review on 📏 Allnice Micrometer Millimeter Conversion Tool by Marcus Zimmerly

The Allnice digital caliper came with three batteries, one in the caliper and two spare batteries. The body is ordinary and very cheap plastic, with no foam or any kind of padding layer to protect the caliper from scratches. When I opened the case the caliper was already on and there were deep scratches on its set screw. I found the biggest problem when I measured the current draw of the battery. It draws about 250uA when off and 300uA when on. That means the caliper will drain the battery even when it's off, so there are two spare batteries in the case. This model does not have data connectivity in case you need it. will sometimes find that the caliper needs a new battery to turn it on.
