I started on regulated devices, but over the last couple of years have shifted towards just using mechanical devices 95% of my time. Selling off or gifting away the majority of my regulated devices. I primarily use a VS DNA 200 to dry fire my coils, check Ohms and for my Boreas.
I prefer the aesthetic and performance of mechs, I like that I can build and tweak my coils to tailor my vape. I like that I have no restrictions on my builds outside of Ohm's law and common sense. And find that Mechs offer better power to weight ratio as well as delivery albeit at the cost of battery life (using mechs on the go means that you are carrying around spare batteries and I am happy to pay that cost).There isn't a regulated device for instance that can match the power output and performance of the Anubis Mod at it's size or cost.
In my opinion the money spent on mechs goes into build quality, engineering and design of the device rather than chips, wires and marketing. Aside from TC, there has been nothing new of any significance on the regulated market. Yes devices have contested claims of being more powerful and have got smaller, but if anything devices are poorer on the whole and have a shorter shelf life. Sigelei used to be my go to brand, my Sig 100w and 150w (which I gifted away) are still going strong, compared to the 213 which aside from its size was disappointing in its build quality and overall perfomance.
Admittedly I do like the DNA chip however Escribe quickly lost its charm for me. I like the concept but in practice was an additional complication, I just want to juice my wick, press a button and vape.
Whereas the Mech market has been releasing innovative exciting designs constantly with top build quality and have been getting better year on year. Devices that have reverse polarity protection, devices that require no tooling to disassemble. Direct to battery connection, customisable options.
Mechs are a life style choice
