Has anyone seen this type of thermostat controller for a fridge. And if so what do they think of its use?

Basically the fridge power cord is plugged into it and the temp prob is put inside the fridge and it turns the fridge on/off to control the required temp. It is basically a switch at the wall for the fridge. I am guessing it would turn on for 10 minutes every hours or so? I am just wondering if that is ok for the fridge? That said, doesn't the thermostat do the same anyway?

For example:

Silver, I have the same type of temp control on my fridge.  Many refridgerator thermostats keep the temperature too cold and can't be adjusted high enough.    In my case the fridge runs for about five minutes every 2 or three hours.  I can't see why it should hurt the cooling unit.  I've had one running this way for several years.

I found this video, I am thinking on making one

Silver, I placed mine about 2/3rds from the bottom near the center, but I found that the temp stays fairly even throughout since the unit isn't running that often creating cold spots.  It's probably more important to check the thermostat against a known thermometer.  Many of the less expensive controllers aren't very accurate.  Mine measures 3 deg F low so I just set the temp higher to compensate.  I set my range to +/- 1 deg and it holds the well within that.
