I have the squape clone from Focal Ecig, and I'd have to say it's %95 perfect. the last two atomizers have been dreams to work on, and they've put my Kayfun lites in the closet. The Squape clone from Focal Ecig is the version I have. The problem with earlier ones, was they coated the center part too far, but that was fixable. These, they seemed to correct. The width is slightly larger than 22mm, like the original. It's by far one of the heaviest and largest atomizers I have, but it also holds a tonne of juice. 510 connector is the right size, and most of my drip tips fit it. It has a glass tank and copper center pin. Air inlets are through the 510, and I use the 510 adjustment to regulate the airflow on my nemesis, but it leaves a slight gap for air. On a flush system, it is too tight of an airflow, so a slight gap might be needed. To fill it, you take it off the mod and fill it along the side like you would a CE5 or an Aqua. The chimney uses a hex head to remove, which is done only for cleaning (nice option/design feature). Cotton only needs to run straight to the juice channels, and I've had almost no gurgles... Only slight gurgles when it starts to run low. I've not yet had a dry hit with it, and that's after owning it for 2 weeks. once you take the deck off to refill, you can also remove the drip tip, and it will sit on the table like a small cup. the deck can be worked on, or you fill it. I don't know what coating they put on the deck and chimney, but it seems non conductive and well coated. The screw leads actually grip and hold the kanthal real well... it's almost as if it grabs and holds it. Either thumb screws or a flat head will tighten it.
The downsides:
It's large and heavy... Very heavy. For those reasons, I wouldn't consider it very portable. Also, the air inlet is through the 510 connector. Even though I like the draw, it is fairly noisy drawing all that air through the 510. The atomizer is stainless, and the top part has a bunch of evenly spaced lines. Although it makes it good for gripping the atomizer, it stops halfway down and gives it a strange look. the juice "port holes" maks it look like something you might see on a ship or a rocket from the 50's.
Overall, I think it's the best design out there ATM, but someone needs to make another clone that is more aesthetically pleasing. Design wise, It's what a large kayfun lite should be.. glass tank, lots of juice, well designed. Kayfuns still beat it in looks, but it has become my at home all day atomizer.
