I would give zero, but it won't let me post the review. The biggest piece of junk I have ever bought. I've been vaping since 2018 and have changed 10 mods. This is the worst thing ever. It has a DNA board, so it does deliver good power, but everything else is trash. Within a month it got scratches on the body because I wear a ring on my left hand. The button feels fake, it wobbles and makes noise. The bottom part, the base, where the screen is too, got covered in scratches from the table and desk where I put it. The worst of all is the screen, which has no protective glass at all. It was moving left and right, and although it is at the bottom of the mod, it has no sealing whatsoever, so moisture that was on the table at the shop where I placed it just ruined it. Most likely a drop of water got inside. It is only good if you keep it in a glass case and look at it. It is useless for anything else. Even if you see it for 30 euros, just don't buy it.
