16 days of delivery, by AE Saver shipping, tracked. Came in antistatic bag. The IIC address is 0x77. NOT compatible with bme280 (0x76) running on the same I2C bus, you'll probably need a hub module for this. The readings are quite odd, well I can explain only humidity, temperature and gas resistance by a burn-in period which official datasheet warned about. If the item is genuine, the lifiteime would be about ~ 10 years, I hope.
Product as described. Not tested yet. Looks like good quality.
