time will tell if it is better than the yellow ones, for the moment I can say that it is better assembled (I recommend, however, to immediately open the various components with the gaskets and remove the processing residues to ensure a good seal), and to calibrate simply immerse it in the appropriate solution and keep the relative button pressed to start the AUTO-calibration (no screws to turn with the screwdriver). batteries and sachets for the calibration solution NOT present.

The product looks great, even if it's done well in aesthetics, the battery is new and the test is working fine.

There is the type of instruction and the battery voltage to be inserted. And there are some settings adjustment tools.

Perfect item. Fast shipping. Excellent seller!!!

AAA+++
