If you need reliability and ruggedness a Mechanical Mod is for you.
My preference it the new generation of TC Mods with Sub Ohm Tanks.
The new generation of VW TC devices are very reasonable and in my opinion Clearo Tanks like the Crown have caught up to dripping in terms of flavor.
The TC APV have the ability to operate on regular Watts Mode, so a TC Mod gives you the expandability to experiment.
Right now I have Mechanical Mods gathering cobwebs because I'm enjoying my current setup so much
Cloupor Gt 80
Udell Crown Tank
I like my Cloupor because it has a smaller form factor then most other Dual 18650 Mods
and it vapes great. It comes with Nickel Coils for Temperature control and a .25 Ohm and .5 Ohm Atties.
Aside from the nickel the other two are stainless steel.
Some contenders are the
IP3LI
Snow Wolf
Joyetech VTC available for $50.00 at Angel Cigs
My suggestion is look these up on youtube and watch movies of the reviews.
If you are new to vaping, don't have 18650 Batteries or a Charger, the Joyetech VTC is a great entry model because it has the battery built in
and USB Charging.
By the way unless the Apv has a passthrough I would strongly suggest that you go with a two battery Mod
My Cloupor is going through 12-15ml of Juice with time to spare for 24 hours at around 45-60 watts.[Depending my Mood]
a one Battery Mod has a tendency to need changes of batteries often especially at high Watts.
Ijoy VTC has a built in 5000mah battery and is supposed to last all day.
