Out of the box mods, the iTaste MVP is still the highest rated, with the original "ego threading" flaw already fixed.
I've had mine for a good week and the only bad thing about it is waiting for it to re-charge after I deplete the battery. Seriously thinking of getting a second one, since the sales keep coming on them. Certainly, I would love to have an OHM reader or have variable wattage as well, but the build quality is exceptional with the iTaste. It's only the size if a pack of cigarette 100's, and isn't very heavy, but it feels sturdy, fits in my hand well and fires perfectly for 2 days before I even see any yellow lights.
I really don't want to have 2 of the same device, and have been looking into the other box mods. I was nearly sold on the TMAX, even though it was bulkier, until Smokey posted that video, and then others chimed in saying that happened to them. The other two are plastic... with plastic buttons...
So if I don't grab a discount Vamo, I will be grabbing a second iTaste in a different color so I don't have any downtime.
