The Uwell Crown 4 Tank is the latest subohm tank from the Crown Tank series. Introducing a patented self-cleaning technology, the Crown 4 Tank atomizers can absorb the e-liquid in the condensation holder through regular usage and vaporizer it, reducing juice leakage and manual cleaning. The Uwell Crown 4 Tank is designed with a 6ml tank capacity with its pre-installed bulb glass, threaded 90 degree screw off top-fill system, and utilizes exclusive Uwell coils. The Uwell Crown 4 Coils utilizes Stainless Steel 904L (steel commonly used in luxury watches) with results in better flavor and longer lifespan. With Pro-FOCS Flavor Testing Technology, Uwell guarantees the perfect flavor profile for a satisfying vape.

Amended review

I figured out the top cap, after applying quite a bit more pressure I got another quarter turn. I wish it was a little bit easier to use. But the build quality and finish is very good

Faulty top cap

I hate to give this 2 stars. The build quality is nice. Good flavor and vapor. However the top cap on mine is either faulted or I'm doing something wrong. It has come off 3 times in just a few days use of normal use. It literally comes off in like 1/8 of a turn or less. Disappointed to say the least.

Beautiful!

I'm going to start by saying out of all the rainbow tanks I own this one really shocked me! It is the brightest and most shiny! That aside, the tank itself is on par with the quality of tanks being released lately. The flavor is great, cloud production is great and it is pretty to look at. I would have rather have seen this come with mesh coils but aside from that this is a great tank. I purchased the mesh coils for this and that is what I've been using so idk how the ss coils that come with it perform.

Don't come into this like its as easy to use as the Crown IIi

I thought this tank was going to be so much greater than my Crown III. I wasright. However, you need to know the following... 1. It is NOT easier to open this tank to change the coil. The coil is still easy to change but if you aren't careful, you will disassemble the whole tank and that is a mess if you still have fluid in it. 2. The glass is NOT held in place like the Crown III. A simple misguided twist and your fluid will be everywhere. 3. Crown III and Crown IV coils have the same longevity. If you vape sweets it will still die off faster than other flavors. Same goes for darker flavors. I love this tank. The flavor is amazing with the new coils, but please don't think that better is easier. This is my takeaway on these tanks. I continue to purchase this type of tank for the ease of coil replacement. Arthritis makes it hard for me to use other tanks because of their replacement requirements.

Best crown yet! A must-have for flavor & ease of use!

Great tank!!! Having coils that pop in & out, make changing coils a breeze, & when the coil is out, the juice doesn’t spill, or leak. I’ve been waiting for a crown w/bubble glass, aside from the expansion glass for the Valerian.
