As everyone else has stated I'm really unsure where you heard to stay away from the MVP. The MVP is said to be an excellent mod and most users if not all users of the MVP love it. I have considered buying an MVP and I have a couple friends who have the MVP and love it. I have been looking at a box mod which is the iTaste VTR. I really really like the iTaste VTR for the build quality, looks and everything it has to offer. Of course with the VTR you have the spinning wheel at the 510 connection area which is said to cause a lot of ohm readings to be off. Innokin has fixed the issue from what they say with the wheel not able to spin. Some shops online or locally still carry only the first version with the wheel that spins freely. But there are a couple stores online that carry the version that Innokin has fixed the wheel from spinning. From what I have heard the fix to wheel not spinning has resolved the ohm issue.
So I am unsure if you were maybe referring the VTR instead of the MVP. Yes some people have said to stay away from the VTR because of this spinning wheel which over time throws the ohm readings off. So if you would like for the ohm readings to not be throwed off then choose the updated version of the VTR with the wheel that is stationary and no longer spins. Best way to find the VTR without the spinning wheel is to contact some shops online that you are interested in buying the VTR from and asking which version they have available to ship.
I plan on my next mod to be the iTaste VTR but the updated version without the spinning wheel connection because I don't want my ohms jumping all over the place and I want the device to function properly for a pretty good time.
The VTR will be my first mod as I currently am using a ego style with a mini protank 2 and its a great little setup but I would like a lot more to be offered. I plan on buying the iTaste VTR this Friday coming up
I hope this might of helped and if not sorry
