Well, from what I can see.... The CoopCreation "Star-Bator" is a FINISHED product. Not just a PART! The item you have shown is just A PART you have to install in a bator you build. The "Star-Bator" Is a finished, ready to plug in and use Item! ( with minor tweeking)
Just my observation!
Added: If you read the info provided on the part page, you can see it says you have to install and solder it together yourself!
Direct quotefrom part shown: "Please note that this electronic kit requires assembly and soldering, and the incubator box must be of your own construction. Also, the kit requires a 12 VDC / 2 Amp power source to operate such as a wall plug type supply. "
