These are an amazing coil, I'll be honest they don't last as long as the 0.5ohm coils but they're not far behind, the big difference is how crisp and clean the flavour is. The Crown III is the only stock coil sub-ohm tank that I use but with the addition of these coils to the range it's hard for me to see myself upgrading anytime soon.

Love my crown3 tank still,liked the 0.4 coils best for flavour but near impossible to find now,so these are am extremely welcome addition!!

I contacted Uwell at the start of 2019 asking if they had any plans to do a Mesh coil for the Crown III as it is still a popular tank and that people don't want to retiring it to upgrade to the Crown IV just to be able to try mesh coils. I heard nothing back from them (not surprisingly) and was about to order the upgrade but then FT got these in stock and I ordered straight away. Well they're as good as I'd hoped for, the flavour is so crisp and clean, the vapour production is thick and rich in flavour. If you're still one of these people like me that hates having to upgrade un-necessarily then I urge you to give these coils a try, you'll certainly not regret the choice.
