I used to own the Mighty+. The difference is the mighty+ uses USB type c vs a barrel port. I also believe the heating element was slightly upgraded to allow for a quicker heat up time. I paid about $200 slightly used through POTV. I liked it for awhile until I didn't. I wish I had went with the Tiny Might 2 purple heart edition. My recommendation is don't go with the Mighty+. Storz and bickel are amazing but what they excel in is the desktop experience and not the portable experience.
