4.0" LCD Indoor Digital Thermometer/Humidity Meter w/ Clock (1 x AAA)

Pros: Large and clear display, nice look. The unit can be put on the wall or left standing on the table.

Cons: A partially drained battery (not dead, about 50% capacity remains) renders the display significantly dimmer than fresh one.
A buzzer is very quiet too, only usable as an alarm in a very quiet room and only if the unit is positioned right next to you (which may be okay for someone).

Other: Does what is is supposed to do, notthing more, nothing less.

Pros: 1 - Very Usefull. 2 - It is a cheap product. 3 - It is the only one that has alarm function, models alike. 4 - Just spend one AAA battery.

Cons: 1 - Alarm function is confusing to use. 2 - Product quality reflects the price. 3 - Although manual in English, it is very simple and does not cover all details of the operation of the product.

Other: It's a great product with excellent cost benefit. I had to judge if your measurements are accurate.
