Hi all, read through most of this forum and I’d like to add my thoughts. I received an MV1 (black chrome) in the 1st batch and I had various issues: Uneven vaporisation Scratchy mouthpiece Heat sink element that mouthpiece slides into not staying in place Charred material after use (almost exactly 50/50 black and green undervaped) Silicone piece that heatsink slots into was not fitted correctly I logged my issues with Ghost and Bud and once I spoke to Ghost and showed them the issues they sent a replacement. Got my replacement yesterday and I noticed an improvement in the mouthpiece/heat sink build - the heatsink stays in place better when pulling out the mouthpiece. But I noticed that the latch on my replacement model was stiff, this was not an issue I had with original model. After a couple of uses the latch just would not budge, I spent almost an hour trying to get it open before seeing a video saying that if you stick your nail in the left hand side of the latch piece and pull from there it will release, so I was only able to get it open like that. I could also see that the uneven vaporisation was still happening and a lot of my material was under vaped. Now I have 2 faulty units, both with uneven vaporisation but with different build issues. From what I have seen so far from using the 2 devices the MV1 does not get close to my Crafty in terms of efficiency and ease of use. I would also add that a friend of mine got the silver MV1, and he has had none of these issues and is happy with the performance of the device. I would just like to get a proper working model in my hands but this has left me very disappointed and I am losing faith rapidly.
