Very cheap. Not exactly. I liked the idea without batteries. I bought 2 of these, put them side by side, calibrated to the temperature, and when it warmed up or cooled down they didn't match the temperature anymore. The humidity sensor is nothing more than another temperature meter. Spend a few bucks on something better, thank me later. Pros: Inexpensive, gives you a rough idea of temperature, can be hung or hung on a counter, washable, no batteries. Disadvantages: no accuracy even among themselves, difficult to calibrate, humidity far and never correct, cheaply made. You can't count on it.
