Someone was telling me that it would be a good idea to have a back up mod. I'm currently running joytech 200w is there a smaller unit that's not as blocky that offers a nice wide range in wattage? Id be happy from 20w-80w. Any suggestion would be great

thanks guys. I'm happy with the joytech and it's only 4 weeks old. I don't have any issues with it but someone mentioned it would be good to have a back up! Do these things break down a lot or do the last a long time?
Having a backup mod and atty are a FANTASTIC idea.
Sometimes batteries vent ruining your mod, sometines you accidentally drop the mod and thr board snaps or the wires break.
If you dont have a backup mod and it dies you will be forced back onto the stinkies just from addiction to nicotine.
Myself i use a Kayfun Monster Mini on a Mini volt when i am out and about.
At home i have two eVic Vtc minis, Sigelei 75, and istick60tc
Attys i hsvd three silverplay nanos, and three kayfun monster mini attys in a drawer, on the counter i havr the Griffin, Goblin Mini, and a Freakshow mini RDA, and waiting for four Goblin Nanos to arrive.
Come hell or high water i am NOT GOING back to thr stinkies when i am under stress.
Have been nicotine free for three months.
