So i just got the squared in for a couple of hours and my god. If i would describe it i would say, its basically what the kayfun v5 should have been for dl vapers. The tank is extremely well made, even better than the v5. The airflow this time, i didnt even need to lube the o rings with vg. Everything was smooth af from the box.
I made alot of pics and didnt know if this site supported the resolution of them and the quantity so i made a album on imgur >

As you can see i fit in a framed staple coil (2x28g ka1 and 8ply .3 ribbon).
In the beginning i was kinda lost a lil bit since i wanted to install it normally past the screws. But since my coil is fairly big/wide the leads of it would kinda get pushed to the coil ( i know from experience this can create nasty hotspots). So instead i chose to wrap em around the hooks and it worked suprisingly well, even though the coil was flat. I didnt get 1 hotspot or uneven firing! (prolly because of the flat connection being OP)
As you can see the driptip seems to be just a tiny touch bigger than the original. Same goes for the neck of the chimney. The Juice flow holes have been made big enough to the point where i can chainvape a whole tank on high wattages without ever getting dryhits.
The original kayfun v5 seemed to be a device that compensated on alot of things to be able to do MTL and DL both. But MTL was kinda airy and DL restricted. This one however is clearly a DL tank (my type of tank). I love how they made single airflow holes on bot sides instead of dual holes. It made the airflow even smoother and even when sucking on it like a madman there is absolutely no whistle, not even a slight sound.
The lowest airflow setting is kinda comparable to the normal kayfun v5. But because this fits a staple build, the flavor i get from it is even BETTER than the normal kayfun v5. YES ITS BETTER (if you're into DL that is).
I found that even with this coil in there it vapes amazing on the lowest airflow setting on just 30w. So you can still buy this tank and use it at work and it will still last you prolly as long as the normal v5 (it has a 6ml capacity with the glass and 7.5 with the stainless steel sleeve). The full open setting is kinda comparable to a goon with 1.5/1 airflow holes open on both sides in dual coil. It is still restricted but if you pump up the wattage to lets say 50 (which is no problem whatsoever) you will get as much vapor production as most high end sub ohm tanks nowadays while still retaining as much flavor (maybe even more since you get rlly dense cloudage and the vape starts getting a little warmer).
I've been rocking it in the second airflow mode which is just a tiny bit airyer than the full open kayfun v5. I've been rocking it at 45w and man, its just incredible. I'd go as far as to say that this is better than any flavor i ever extracted out of my goon OR kayfun v5 or any atty for that sake.
And this is without a doubt the smoothest airflow i have ever experienced. Going from dual holes to single big holes in the airflow really made a HUGE change in smoothness.
As far as the feel, it feels very sturdy. If you own an authentic kayfun v5 you know what i'm talking about. My kayfun v5 is prolly 2 times as heavy as my NRG tank from vaporesso. Yet the NRG tank is 25mm and the k5 22mm... So needless to say, this 25mm is quite heavy. As i mentioned its even better build than the k5 and feels alot sturdier and smoother too. As you can see in the pics the topfill juice holes are a tiny bit larger too.
Conclusion/tl;dr :
-If you are a kayfun v5 owner and you are a DL vaper, or even if you arent a k5 owner and you are a DL vaper and you've been searching for a tank that you can take with you and lasts you a whole day.
-A tank that can perform and produce serious cloudage when you want too.
-A tank that will produce incredible flavor.
-And above all, a tank that feels like i'd prolly lasts till you're 90 years old and ready to pass it to your grandkids.
Then yes this is the tank for you. It's everything the kayfun v5 is but better, ALOT better.
Ofc this only applies to DL vapers, as this isn't a MTL device by any means.
If you are a MTL vaper, i would suggest you check out the Kayfun prime. Heard great things about that one also.
except for the airflow, which is hard to see in the vid.
