Own a Reo Grand mechanical squonker fitted with a Reomizer RDA, but it's fire button and overall shape hurts my hand. It's mostly being saved for a rainy vape day, but I'm still glad that I own one.
My second most used mod currently is a
Segelei Fuchai 213 Plus, which appears to be very similar to the Fuchai squonker you linked. It's a very well made mod. Uses up both batteries in a days time using a sub-ohm tank (@ 30 - 40 watts) The only reason its not used more is I've becomed so attached to my newer
JAC Vapour B DNA75. It is extremely comfortable to use, is very small and extremely well made, and fires my sub-ohm tanks (@ 30 - 40 watts) all day with a single 18650.
I've used both regulated and mechanical mods over the last few years. There are pro's and cons for both. I've used regulated exclussively for over the last year or so. I like being able to adjust my wattage (and vape) on the fly, and there is no denying that regulated is the
safer way to go.
The Pro's & Cons of Regulated vs Mechanical Mods:
Regulated Pro's:
The battery power to the atomizer is controlled (or regulated) to stay the same throughout the battery charge, from a fully charged battery until fully discharged.
The power can be adjusted to increase or decrease the voltage by the user, allowing the user to change their vaping experience.
Has built-in protective circuitry against atomizer short circuits, shorts in the 510 connector, or fire button; accidentally putting the battery in backwards; over discharging the battery; accidentally pressing the fire button too long (auto cutoff timer); and over-heating of the processor.
Has built-in battery voltage and atomizer resistance meters to check battery voltage status and the ohm rating of the coil.
Regulated Cons:
Generally speaking, may not be as well made or as durable over time compared to a mech. Electrical components may fail over time or from physical abuse.
Unless it is a "high wattage" regulated mod, will not be able to fire a sub-ohm resistance coil.
Mechanical Pro's:
Generally speaking, are made to be more durable and able to withstand some physical abuse. No electronic components to fail.
Mechs are able to fire sub-ohm coils because there is no protection circuitry or processor amp limits to prohibit it.
Many mechs are machined to be quite beautiful, nearly art pieces. Many are manufactured in a limited run, in limited quantities, and inscribed with the number on the mod.
Why do people choose a mech over regulated?
Mechanical Cons:
No protection circuitry. This is the big one for beginners. The new user must always be aware of the signs of a short circuit, which could cause the battery to vent into thermal runaway. The mod must have ventilation holes in case you experience a venting episode and which should prevent your mod from becoming an exploding pipe bomb.
No voltage regulation of the battery. As the battery drains from use, the vape quality will progressively diminish.
