    Uwell Crown 4

    Posted by Bob Carpenter on Feb 01, 2020

    Thanks again Eciggity for the great service..I have the Falcon King,Uwell Crown 1 and uwell Nanchaku to compare the Crown 4 with..The Crown 4 has the best flavor of all of them for my style of vaping..I go for flavor first not clouds..I find the mesh coils best for me...Coil life seems a bit shorter than some others,I use 50/50 Tobacco blends,wattage about in the middle of recommended..I don't care for too warm of a vape,clouds are fine for me..No leaks,fit and finish are very good..Even with all the hype,for me,the crown 4 has better flavor than the Falcon King,I taste more of whats in the liquid mix,slightly sweeter..The Nanchaku is a close second but not quite up to the Crown 4..This tank is a flavor machine with OK clouds,I also had an RTA and the crown still has better flavor to me..The mesh coils do take maybe a quarter tank to break-in..Bob

    Best Crown ever!!

    Posted by ZeeMill on Jul 29, 2019

    Crown 4 tank is better than I expected. Still the great flavour as the Crown 3 - but zero leaks!! And the tank is larger so less filling! I have had this for a week and I still catch myself checking for leaked juice. I loved the flavour with the Crown 3; but the leaking drove me nuts! It was time to move on and I am glad I did!

    Crown 4 - Worthy addition to your tank collection

    Posted by Jim Clement on Nov 29, 2018

    Combines the best features of the 2 and 3. Great airflow. Cloud city with max VG. No more condensation problems. 904L coils last a long time.
