I received my trident clone last night. reminds me of the Stanley Cup a lot in hockey.
A couple things about the device. The connection at the bottom, the threads are pretty horrible. Bad machining is the only way I can explain it, really. The device had a broken O-ring, which is whatever I suppose.
3 main problems with this device
1. The device when fully assembled, the middle shaft piece is too long. The unit can not be placed together flushed as it was intended and line up properly with the air holes. You either have to flip the shaft upside down so the top isn't flush, or vice versa. Measure twice cut once darnit
2. The pins that you run your coil through aren't made like the real thing. Working your leads through the posts is very difficult as they are at weird angles and under the lip of the dish/cup that you drip into. Very frustrating.
3. There's only one air hole. If you want to dual coil, you really want two air holes. Theres one air hole and the air control only has one set as well. i don't have a drill press so i'll try to find someone that does.
Fix : Basically, you'd want to chop a whole section off of the top cap cap. This would alleviate the problem of the middle shaft being too long.
You're also going to want to drill another set of air holes for the control and an air hole on the other side for the second coil. You'd want to keep the option of turning one hole off if you only want to run a single coil from it.
It was cheap, so I can only complain so much I suppose
