I bought multiple laser meter. Unfortunately one was not working correct. I made contact and the same day it was arranged to come and collect the device. Investigation need to be done. I yesterday received a brand new device. Thank you for the good service

Unfortunately I couldn't like any of the devices with cellphone using Bluetooth.
But the rest of the devices functionality are working great.

Unit looks well made and does what it should. It is a little smaller than I anticipated, not that it really matters. Having only the two buttons is good for simplicity sake, but they have many uses depending on whether you short press, long press, double click etc.
It does look like the companion mobile app they mention (that supposedly can connect via Bluetooth) is no longer available or was pulled from at least the Google App Store. Not the end of the world but would have liked to see how that works.
At the price, it is really worth it. A similar specced unit at a local hardware store was about double the price.
