This Uktem kit is great! I love the style/ the way the Prime looks with this kit/ it’s really sharp! And it is a much more durable setup- while still maintaining a view of your juice level! I highly recommend to anyone with the Kayfun Prime.
Creme de Vape has the best customer service and wonderful product selection!

I bought this as I didn't want as much breakable glass on view and a stronger ultem window for travelling/going out. Initially, I thought this wasn't as "pretty" as the original, but my views have changed and I now actually prefer this setup. The window allows you to keep an eye on your juice levels (unlike the all metal barrel) and it works as good as the original glass option.

As it's an original Svoemesto product, there's no issues with fitments and the threads/machining are all super smooth.

All in all a great product, that will make your tank less prone to breaking and continue to use it as intended.

Looks great. Easy to use. Very nice for seeing the juice level. Highly recommend.
