As the new owner of that afore mentioned red evercool box, I have a few things to say about it.
This thing is pretty awesome.
The inside of the box is extremely clean, and by that I mean everything is neat and organized, and even the soldering work is nice. The big red button that was put on it has a very nice tactile feedback. It's stiff but not too hard to press, and when it clicks, the button gives completely. There is no half way pressed with this button, when you press it, you most certainly know it's on. Plus, it just feels nice, it's 1 of those buttons I just love to press.
The airflow is nice around the connector, this varies from 1 e-cig/mod to another, even when the same standard connector, in this case 510, is used. I noticed on this connector that it has a fairly raised middle section, this might have something to do with the increased airflow, and also likely makes better contact with the middle post on my cartomizers. I've had to press down on the center cup of an E2 cartomizer to get that center post pushed out some in order to make contact at various times with other mods, maybe this will solve that.
The red led is nice and isn't too bright, the on/off switch at the bottom is extremely useful, as is the fact that it has an evercool regulator and greatly extends my poor little 14500's battery life. The voltage dial is stiff enough to not change when it's slipped in your pocket, and provides decent grip. The led light flashes when the batteries are low, I don't know how this works, am fairly sure it was intentional, and it sure is useful. I know this sounds like an ad, but I really do have a hard time finding something to not like about this mod. If I had to think of something, I'd say it needed a separate on/off switch for the led, so the little lady doesn't annoyed with it in bed. After all is said and done, I really don't see anyone beating it for the price.
James, you did an awesome job, and I appreciate the extra work. I very well might be ordering another 1 (minus the led for bedtime use) very soon.
