Excuse me but I am not hating on it. I have been vaping oil with electronic vaporizers for a long time now and have gone through so many vaporizers. I know what I am doing. I will post a video so you can see yourself. If I am spending $300 I do not expect it to leak at all!!! Also, i should be able to use whatever concentrate I want after spending $300 And u can't repack it with wax after first use until the insert cools down.
