Review on AMTAST Digital Stainless Measuring Conversion: Perfect Precision and Accuracy! by Carlos Reyes

These calipers are great after about an hour break in period. When I first received the item, the sag is about 0.0005. I use the term "slack" because I don't know the correct term, but I basically discovered this while zeroing (and zeroing) the caliper under normal effort. I was then able to press hard and get the caliper to read -0.0005. After a day or so of use, however, that "sag" is more or less gone, and it seems to perform on par with the $100 caliper I use at work. In short I really like this caliper, it seems to be well constructed and does a great job of measuring. A solid 5 stars for the price! The caliper part is a bit larger (about 2mm) than I'm used to (see last picture). The wheel is very coarsely structured and enables very good grip. The measured values are easy to read. Comes with two batteries and a screwdriver for installing/replacing the battery.
