Very poor instruction manual
Great tool for the price and pretty straightforward and easy to use. However, the manual is extremely lacking, and I am unable to take advantage of the "easy field recalibration." The manual describes putting the power switch into the CAL position, but it doesn't exist. The manual also shows two different sized tripod mounts, but there's only one. This unit cannot be used with a construction tripod, only a camera tripod.

Lightweight, compact, adaptable.
This unit works well and the mounting adapter is versatile, however, the magnets are a bit weak, so keep a grip on it if you are working at height ! It would be good if they offered an adapter arm that would let you attach it to things ABOVE the device so it can be hanging down (like magnetically attaching it to the BOTTOM of a steel beam). The owner's manual doesn't show you how to remove the battery compartment cover, so it's a bit of a fumble the first time (the manual does tell you, but not very clearly). Pay attention to the LABELS for the battery polarity, because the battery holder is constructed so it LOOKS LIKE they all go in the same direction, BUT THEY DON"T ! The storage bag is just large enough for the device, but no spare space / pocket for the attachment strap or storing spare / removed batteries.
