I have Copper Vapes & SJMY clones, A lot of people are turned off by the plastic Tanks.
Their missing out! these Rose V3's have flavour for days, The JFC works good, capacity could be a little more, but the nice small look is good to. The Rose V3 is in my top 3 single coil tanks!
Only little down fall I find & it's with both versions I have, is a bit of leaking thru the 510

It's not that bad but I find I have to remove them & wipe the bottom & the 510 connector on the mod occasionally. I guess it's the SMY version with the 510 pin protrude issue? cause both of mine are good
