Digital Compass Security Clip with Thermometer and Watch

Pros: Well, it works. It can give you the temperature in ºC and in ºF, it has a compass, a clock, and it has a blue back light, very useful during the night.

Cons: It's not very well build, it looks very plastic and not very well assembled. Not very strong. Also I'm not sure if it will support rain or snow. The thermometer is extremely slow. I bought this device to check the temperature in the streets while walking, as i moved from Spain to Norway and I'm still courious to know how cold it is outside, and if I get out of the car and start walking, after 10-15 it still reads the temperature inside the car. Also, the compass need to be calibrated, as explained in the instructions, but it's nearly impossible to do it. I have tried several times, turning myself slowly with the compass in my hands, trying to follow the 360º turning in one minute, but it always says that need calibration again. Anyway, it's quite precise, even without calibration. It's as precise as the iPhone 3GS compass. Not professional precision, but enough for a normal user. I think such quality level should be cheaper.

Other: Would be more useful with a "faster" thermometer. And I think the calibration of the compass is not necessary for a normal user (and a professional one should buy professional devices, not this).
