Very pleased with fit and functionality. I needed this ASAP to review hot work and it did what it was supposed to do. It was a little difficult to figure out how to reset, but once I figured it out, it was very easy to use. You can also "set" +/- your zero as needed to calibrate it for whatever reason. I don't know how it will be useful to me, but the option is there and they've spent time developing it, so it should have a purpose that I haven't encountered before. I wish there was a cheaper option but this was the only model I found that did what I needed.
