product received in good condition. indoor main unit is bigger than my 6 inch smartphone and is bit heavy in weight than expected. All functions having calibration option which is awesome. Display is visible without backlight also. Screen display with backlight visibility is best if kept below eye level, from other sides it doesn't have good visibility. Barometric pressure was the main reason to buy and it's sensitive too, but it's brown color is difficult to read without backlight. Outdoor unit looks like ac remote but no backlight. visibility is good. It sync temp and humidity to main unit without any time lag. The main unit us also powered by adapter provided which is 100 to 240v input and 5v output. Adapter socket in main unit have groove, so no extra bulging. While plugged in, I taken out battery and it was still working. No charging current is provided to battery. Additional plug was packed outside the box for compatibility, but it didn't required here in India.
