Review Summary
The Open Sesh is one is the smallest vapor cups available, with the smallest glass container as well, but it’s also the easiest to use, in my opinion. It has a clicky button—unlike the Omegatron, which doesn’t have a traditional activation button, and unlike the Zenco, which uses a flush, non-clicky touch button. The Open’s button is easily my favorite. It also has four voltage levels, and for solo users who want a quick sesh, the “Sesh” is a great option in 2026.
