I am thinking about purchasing coils from vapor shark, is this a trust worthy site?

I have the Koopor Mini mod the picture in my profile. I have an atlantis 2 subtank

I just recently purchased a mod capable of temperature control. I purchased nickel coils for my tank. I am not understanding how to set up the mod in order to use the nickel coils. How do I know what temp. to set the coil to? What is the proper protocol when I first put the nickel coil on my mod. What should the settings be? Thanks
