I've been using the Rogue for a little over a month now. I am delighted, I even wrote a short Rogue vs Mighty comparison, which I am posting below. Unfortunately yesterday this happened, first the Protect E20 error and now also E08. I wrote a message to Vapefully yesterday, still waiting for a reply.
Rogue vs Mighty:
After a long search for something more handy and portable, but at the same time not worse than Mighty, I chose Rogue.
If you like to do one huge session, Mighty is a slightly better choice. I like to sit down and take it easy and vape slowly, so for me the Rogue is the perfect choice. The Rogue chamber holds about 2-3x less herbs (I always use capsules) compared to the Mighty. The same amount of herbs in the Rogue you simply have to separate into 3-4 capsules/sessions, so the fun is longer. If you have the capsules prepared then swapping for fresh ones is about 5 seconds only, so it's not even uncomfortable. In addition, with capsules, the chamber of the vaporizer after a month is not dirty at all.
The Rogue is a device with noticeably more convective heating, you have to take long slow inhalations to get a lot of vapor. The Mighty's conduction heating produces so much vapor that it comes out of the mouthpiece on its own, you don't have to inhale hard at all. The vapor in the Mighty is noticeably cool. In the Rogue with a standard mouthpiece is warm but not hot (I personally prefer this).
The Rogue heats up in 15 seconds (the Mighty over a minute), and you can use it almost on-demand, as well as stop the session without wasting of herbs. To get a similar flavor and thick vapor, the Rogue needs to be set 10-15°C (50-60°F) lower in temperature. For example, the best temperature in the Mighty for me is 185°C (365°F), while in the Rogue it is 175°C (350°F). At 210°C (410°F) in Mighty the herbs turn brown, and in Rogue they are much darker, even almost burnt in places.
I am thrilled with the Rogue and at this point it is the better choice for me. However, I don't want to decide which device is better. They are certainly two strongly different devices, but both equally good.
P.S. Sorry for any mistakes, I don't use English on a daily basis.
