I have been interested in mech mods for awhile now, mostly because I have not been able to get a regulated device to last more than 6 months. I either have terrible luck or am hard on my equipment. I use RBAs in all my tanks and have a Velocity dripper clone I bought just to play around with.
I haven't been able to figure out if it was something I really wanted to invest in. I understand all the basic principals of their operation and what not and have read a bunch of of articles about their safe operation. So I was asking one of the guys at a local B&M about them. I explained to him I really didn't know if I wanted to mess with one or not. He kind of explained how they work and how the coils are really the key to making the device work the way you want. Then he told me that they have some on sale for $5.00. He pulled out an Eh Pro Dynast and a Kamry K100. I ended up picking the Dynast, new Samsung 25r and a spool of 24 gauge kanthal. I figured, $5 was a reasonable cost to at least try one out.
Got it home put the battery on the charger, wrapped up a couple of coils wicked it up. It was Too hot and spitty, resistance was around 2.8ish. I pulled it apart and Wrapped another coil, too cool and too long to heat up resistance was around 4.5. So I pulled it apart again and wrapped up 2, 24g, 6 wrap contact coils on a 3mm Screw driver came out to .35ish. (I preface the ish part with the fact that my eleaf ohm meter read the atty at .35 and my IPV D3 read it at .3). Wow, just about perfect. Nice vapor production and great flavor. A little cool but I tend to like a little cooler vape. I will definitely play around with it some more but I have it running pretty well right now and am enjoying it immensely. There is something satisfying about getting a nice vape off a totally mechanical device.
I just wanted to share my experience, Hope I didn't bore you all.
