She said the majority of the problems are associated with using too much liquid and allowing the liquid to invade the switch. She also says that most of the people have had the wetbox for months without a single problem.
So it's user error? LOL
It seems that the unit itself is 'allowing the liquid to invade the switch'. And why is the switch located right where the leakage
into the box
will occur? Everyone at some point with any atty/carto will overload the liquid. Over squeezing, over filling carts, over dripping... we all do it. The excess should stay outside. That's why sealed connectors and manual e-cig batts are preferred.
And what about the switch itself?
a bottom juice feeder that will work with 510 l.r. and reg. attys.
A standard Joye 510 atty will want to pull about 1700mA. A LR at 1.5Ω will want to pull about 2400mA. That little tact switch that is used is rated for about 50mA. So with a LR atty the switch is expected to handle
48 times the current it's rated for. These types of switches are also not very robust, they are not made for the constant activation that we subject them too.
Trying to cram the components into a 2AA box is part of the problem. There is no room for a decent switch, the switch is right next to the leakage point and refilling means carefully navigating the wiring. Leakage into the box is a design flaw the wooden bottom feeders out there don't have.
HighPing's mod addresses two of these issues. He moved the switch away from the juice bottle, placing it under the battery, and sealed the tube/needle atty connection.
