Package arrived well packed. The product works, fits the description. Good correlation between the inner and outer sensor. I've placed the outer sensor about 7 meters away and it works. The touch screen is not great, but works.
Everything is fine. The item was shipped fast enough. There was something wrong with tracking but it did not affect the delivery. After one day of usage I can confirm that the device works properly, the measurements are accurate, the range of connection is enough for a house with two thick walls on the way. I am satisfied and recommend the Seller and the product.
