This appears to be very well made, high quality, nice choice of materials and finish. I appreciate the cover bag. Display is lit and very easy to read. I had no problem with calibration, as apparently one reviewer did. However-- note that the level calibrates to Zero at whatever angle the level is sitting during the cal process. It does NOT calibrate to absolute horizontal. So, if your "calibration" surface is off horizontal, the cal process sets that surface to Zero. The benefit of this is that whatever other surface you read produces an offset to the "calibration" surface (e.g., for cutting boards to fit accurately to both surfaces). I would prefer that the manufacturer called this process "Reference" rather than "Calibration", as the latter word strongly implies "with respect to a universal standard (i.e., local horizontal). But if you use the tool as the manufacturer intended I think you will be very pleased.
Also note that the level includes bubble vials like those of a standard "dumb" level-- so you can detect if your reference surface is off level, regardless of how your level happens to be "calibrated". Good feature!
