Why? Because variety is the spice of life. I'm happy with chicken but I still like to try other delicious animals. I think mechs look great and they are small. It doesn't hurt the prices are really good on some. Besides, I don't need a reason to buy one. Just because I want one is good enough for me.
Nothing wrong with that concept at all. I like variety, too, especially with my juice flavors. However, despite owning several types of mods both unregulated and regulated, just two of the same type get nearly 90% of my attention.
A big plus to me for the regulated mods is keeping the vape experience the same from start to finish on the same battery. A mechanical (unregulated) mod will not have a microprocessor on board to do that, so the best vape will be the first one on a freshly charged battery; it will be downhill the rest of the way after that as the battery depletes its stored energy.
If you are used to adjusting your voltage to your flavors, you'd no longer have that option with single voltage. I found that I was always attempting to adjust voltage when I made a short return to mechs for a while. I typically switch out 3 - 4 flavors a day on my tanks, and each one uses a different voltage "sweet spot". Does it make THAT much difference? No, but I know I missed that option when I no longer had it.
When I began using RBA's, I had full intentions of putting a AGA-T on my rarely used Silver Bullet. The thing is, I found that I don't care for ULR coils or low resistance vaping in general. I prefer my coils to be around 2.0 ohm. And I found that I preferred the RBA on the Provari's more than the SB because I have more options to adjust the voltage to the flavor...again.
I totally believe mechanicals have their place in vaping, but for me I will always prefer the regulated vaping experience.
