As stated before mechs aren't that difficult.
Just realize that batteries have limits if you're going sub-ohm.
Personally I like between 1-1.4 ohm coils which with a quality battery (AW IMR, Sony, etc) is well within it's limits.
A cheapo ohm meter or a VV/VW device that reads ohms is a must.
Make sure you're connections are good within the mech, and between the mech to the Atty.
My order of operations:
I wrap my coils then check ohms on either my MVP or on the cheapo ohm meter I bought.
If within range I test fire, and tighten up the coils.
Check ohms again.
Connect base of atty to top of mech mod, and make sure the adjustable pin makes contact.
install battery in mech, install top/base of atty to top of mech.
Adjust switch pin, and install base/switch of mech checking for good contact of battery terminals (shaking you can hear if it's loose).
Once on the mech with battery installed I test fire the coil again checking for good glow (inside to outside) of coil, and good fire time.
Wick the coil
Test again to check for vapor production.
Continue building the atty to completion. One more test fire to hear crackle of juice, and feel atty, and mech for any undue heat (this would mean a poor connection somewhere).
Fill with juice
Enjoy.
Check periodically that everything is still making contact. Some mechs will unscrew a bit in your pocket. A second to twist the bottom cap/switch to snug before use is better than a hot mech.
Personally I love the mechs.
Gives me a lot more control over my vape without any electronics to fail me.
Test fire with wick, and juice before building atty>>>
Some of my toys (Notice the ohm meter in the background)>>>
My go to pocket vape (sorry for the dirty hands but I was in the shop doing some woodworking)>>>
Vape on.
