Hi
@Kato2611
Usually cheaper vapes don't tend to have great production but I would have expected you to feel something.
I guess the obvious things for me would be what temp is it?
How are you packing it? It's a conduction vape so you'll want to pack the chamber tightly for best results.
Is the mouthpiece clean? Sometimes they can get a little gunked up, but again I would have expected you to have vapour stop to have this.
It may just be a faulty device. I don't think there's much more advice I can offer, I have a lot of vapes but given we inhale from them I tend to stay clear of Chinese plastics - one of my first ever portables was a flowermate and I really hated it.
