I love my K100 mechanical. Use it with a AGA-T RBA set up with very low resistance coils. You said you know nothing about mods, so here are a few pointers on the K100. It is mechanical so there no electronics in it. Nothing to protect you from shorted coils or over discharging batteries. If the batteries you get with the kit are protected, all that should be taken care of, as long as the batteries protection circuitry does not fail.
It's is not a mod that I would recommend for a newbie. I use unprotected batteries to not limit the available power. I check the battery voltage off the charger most times to make sure it's not over 4.2. I check the voltage again as I sense that it's getting low to make sure it's not going below about 3.4. If I sense a shorting coil I fix it right away. I would not use anything other than RBA's on this mod. There just is no point in my opinion. If you decide to run with this mod, please learn about mechanical mod safety issues. They can be very rewarding, but can also cause grief. Best of luck with it
