I received my Throathit Twin 18650 variable mod this morning from Throathit on UKvapers http://ukvapers.com/topic/4828-throa...-variable-mod/
I knew it was good from researching it and looking at reviews but seriously this is an unbelievable piece of kit and I would recommend it to anyone. It feels so solid to hold and you can tell it was made with a lot of love.
It gives between 3V and 5.8V using the dial knob on top. The performance is excellent and it gives the voltage reading under load while vaping with the button pushed in, you just need to look down on the meter as you are vaping to see the indicator.
I've already tried it with a 1.5 ohm dual coil carto with tank at 4v with tobacco flavoured e-liquid and the throathit vapour and flavour are all great. I also tried it with a 3.0hm boge and a nice vanila/chocolate e-liquid at 4.5V with tank and it just performs brilliantly, the most satisfaction I've got since I started vaping.
It comes with 2 AW IMR 18650 batterys inside the bombproof case and just needs to be plugged in like a mobile phone to be charged. Going on other reviews I'm sure it will only need to be charged every 2 or 3 days and it can be used while in charging mode also.
I'm not going to say anything about the safety features as its all in the link above if anyone wants to know other than it does have a lot of protection built into it.
Here's a picture of it, I asked Throathit to change the usual red button to black and I also got him to relocate the 510 connection so I'd be able to use a tank on it.
