It´s easy to handle and use. Light weight and it seems to be accurate enough. I`ll make some more test with them, but is just what i need right now. Very good price/quality rate. i like it.

Taken out of the box it didn't work at all. After a few times of removing and inserting the battery container, it started to work. There must have been some lack of electrical contact between the PCB and battery container. The bigest problem is that there is completly no indication of battery polarization, therefore I attached some pictures with properly assembled batteries. There is an information in user manual that thsi device must be calibrated when is often used. The problem is that there is no way to calibrate this device.
