Choosing the right IR thermometer

Hello , I want to use a distance thermometer with Arduino mini pro in order to capture and store temperatures from distance. I am between these 2 choices:

choice_1

choice_2

What is your opinion?

Buy the cheap one and if it doesn't work for your application buy the expensive one and you have a cheap one in the cupboard for a rainy day!

What is the maximum distance that the MLX90614 can measure?

Here is the datasheet Datasheet for MLX90614 - Free Download #Melexis

It does not say something, that's why I asked.

It measures temperature, not distance.

There is no "maximum distance". The MLX90614 measures the average temperature of the entire, 90 degree conical field of view.
