I am a lot more impressed with the ruzgar, although I havent ordered one yet.
It's kayfun styled build deck with a quartz tank and windowed stainless steel sleeve.
RÜZGAR RTA (English) by HIGHWIND ID - VIENNA VAPER REVIEWS - YouTube
Ruzgar is OK, but it has issues, I'm not all that thrilled with mine, Top fill is not the best on it, floods easily if not careful, airflow not the greatest, a bit tighter then a KFL+, juice capacity not the greatest, all that and 4 times the price!
I prefer the look of the Ruzgar, but other then that, I just don't see any benefits. What I would consider a decent though somewhat costly alternative to the HC would be Quartz kit, AV threaded top fill cap, and chimney, added to your choice of KF, and you have a winner. But for the $32 I paid the HCigar is a decent option.
