Does anyone know if there is adjustable juice flow through the drip tip like in the mister silica? Is it worth selling a KF 3.1 to pik one up? Waiting on more reviews and info to come out before I commit to a lowly 21mm -_-
The juice control on the MISTer is much easier to use then the Aqua. The air control of the Kayfun 3.1 is much easier to use then the Aqua. Having both juice and air flow control in one device, that's what makes the Aqua worth trying/having.
I've used the Aqua for a few days now and I am enjoying it. Dual coils with dual air channels make for much denser clouds then either the kafun (3.1 or Lite) or the MISTer. I would be hard pressed at this point to pick a favorite since they all fill different roles.
1. MISTer Silica Hybrid: It's a hybrid so it looks the cleanest. Very easy to set up. Juice control is positive and easy to see how open you have it set with the full open/full close lines on the tip. Issue with flooding when refilling that can be overcome with careful filling. Only mod I currently run silica on due to it's solid tank and leaking issues.
2. Kayfun 3.1: Very easy to use airflow control but even at wide open would never be considered "airy". Tons of flavor due to the placement of the air channel under the wick deck. Easy to coil up, quick to clean. If you get the right tip or bottle, the juice fill port is a god-send, with the wrong tip or bad alignment it's a PITA. Expensive and very tall, looks "off" on some mods.
3. Kayfun Lite: Easy to set up, lots of places are carrying this now so parts are easier to come by. Both the Lite and the 3.1 give some of the best flavor you'l get out of a rebuildable. Will not give you large clouds and is 100 percent the wrong device to chase sub ohms due to heat issues with insulators melting.
4. Aqua: You get air flow and juice flow control. This is excellent if you're someone who likes to try different juices with different vg/pg ratio's. If you like to try different materials (cotton, silica, ekowool), these controls give you the ability to fine tune to your build. It's a well made mod, the machining is very clean and the look is beautiful to me.
A word of warning, my aqua was one of the dirtiest devices I've ever bought. Machine oil, fine metal particles, and grease on almost every part. I was very careful with my cleaning and did get it all off, but it took longer then any other.
It is built to handle sub ohm, so you can chase the clouds and it does give you some good clouds out of a device of this type. Flavor is on par with the Kayfun but slightly muted (IMHO).
All in all I would say I like the Aqua and it will be part of my normal rotation. It's not the end all be all that some reviewers have seemed to suggest, but it is a great little device. If you have the means I would suggest picking one up.
To clarify, I do own and use all 4 devices so i'm speaking from personal experience and opinion.
