Ok I modded this thread.
I'll start with one I'm really intrigued with it's technology and performance potential.
It's "the Precious" made by Caesar in Romania. Which I've made up my mind to order the new version L which will be avaiable end of July. He makes this in 3 different sizes. The Precious L, M, S. S being the smallest 10440 mod in the world, M being the smallest 14500 mod in the world, and L being the smallest 18650 mod in the world. He's also making the very limited edition U ,only 6 made for the 1st 6 original purchasers of their first model the Precious L. New features on the Precious U will also be implemented in the new L and will eventually be in the M and S versions.

Here are the new features of the U very limited edition:
These features will also be in the new version of the L.
Besides the usual features of the L:
* best ventilation system, directly over the battery vent holes
* touch sensor
* smallest size available
* lowest possible internal resistance
* over-current protection and under-voltage protection
The currently implemented and tested features are:
* undervoltage protection with visual indication, unit shuts down afterwards, not allowing to deplete batteries to a dangerous level
* overcurrent protection, resets itself when shorted atomizer is exchanged, the user just needs to exchange the shorted atty
* general on/off switching
* constant voltage from the first to the last vape
* very easy voltage selection on the Precious itself, with visual confirmation
* variable from 0,0V up to 8,4V in 0,1V steps, without the need of multi-meters, voltmeters or any other equipment
* 3 colored LED for status indication, can be turned on or off for stealth usage from the unit itself
* green led intensity can now be user selected for stealth and normal mode
* menu to select voltage and LED mode operated from the touch switch
* just one touch switch for user input, retaining the beautiful simplicity of its predecessors
* settings are stored in the unit and retained between battery changes
* possibility to use it with or without the automatic juice dispenser
* atomizer activation limited to 15 seconds, allows long drags without hitting the safety limit. 15 seconds is a very safe timing, not limiting the user while still not destroying the atomizer if it is reached by fault
* user will be able to change cutoff timing
* the first 8 seconds are indicated by a green color , from 8 to 12 seconds with a orange color and from 12 to 15 seconds by a red LED color
* timing of different colors can now be user selected
* when the batteries are close to depletion, the first 8 seconds will be lighted orange instead of green to let the user know that batteries will need to be replaced (stevemontuno’s idea and request)
* if the atty activation limit is reached, the Precious switches to OFF state, protecting the user, batteries and atomizer
* if left powered on and unattended, the Precious will shut itself OFF after 30mins of inactivity, for safety reasons
* can now be changed by the user in 1min increments or turned off completely
* it detects and applies the correct settings when powered by 1×18650, 2×18350 or 2xCR123A while the U will also support 2×18500 in selected units
These are all the features that I want and need in a PV. I tried to create the simplest and most user friendly device, incorporating all the possible safety features while keeping it small in size and still allow for versatility.
"If any of you have some ideas, need a feature not implemented or would like to contribute some insights from their own experience please do now, as the final moment is nearing fast." quote by Caesar the designer.
Settings that can be changed on the Precious itself:
* voltage, has menu for volts and tenths of volts
* LED stealth mode: on or off
Settings that can be changed through a computer application by connecting an adapter instead of the atty:
* voltage
* stealth mode
* LED brightness in standby mode (stealth or normal)
* auto shutdown period if left unattended in standby mode (1-250secs), can be turned off
* LED color times when activating the atty (default 0-8secs green, 8-12secs orange, 12-15secs red)
* activation cutoff timer (default 15secs cutoff)
