“Quite good but nothing new. The fill system not as good as the previous one the V2 bottom fill, I suppose it's done for manufacturing cheapness I only brought it as my V2 has a malfunction with the chip and I can't find a replacement chip,I might remove the new ones d put in the V2 and convert the V3 to a open box mod when the guarantee period has ended will be a good v1 lol”
