I have two MV1's. One I bought and one resulting from beta team participation.
I do not doubt anybody's claim that their MV1 is not operating properly and there is no way I would contest anybody's posts along those lines.
But mine work perfectly as do quite a number of other people. A large number including many very experienced vaporists.
I too don't like the crucible design as I just think its a bit of a PIA....but pretty much all vapes have something to object to. Some don't like bags and diss the Volcano. For others its a god send. Some object to plastic housing of the Mighty/Crafty while for many others this is THE consistent, workman like, vape of all portables. Some like unregulated vapes like Milaana while others think that's crazy. Etc, etc., etc.
So, while its not my favorite design feature, its more an annoyance than a serious issue for me at least.
I do get very smooth, powerful vapor from my MV1s. I'm sorry that not everybody is experiencing this also but I have watched Ghost...over a long period of time...provide good customer support including warranty replacements, until they get a user happy with an properly operating device.
The only other thing about the MV1 that I think needs to be high on the priority list for improvements is power control. Its simply a fact that the units run hotter on the first load of a fully charged battery and then drop down a bit for the duration. I just up my temps to 410 or so on subsequent loads and it vapes just fine....but I would like to see this corrected. Optimally, power to the coil should be consistent across the discharge curve of the battery. Now, power management (and especially determination and display of remaining battery power) is notoriously difficult to do with Li Ion batteries but others do seem to have done it better than Ghost's initial try.
If I had an MV1 whose performance I was not satisfied with, I would definitely contact Ghost for repair/replacement. That's why we have warranties, yeah?
