About this vaporizer
The Convex 1.0 is a butane convection vaporizer that takes its time — eight seconds to heat up rather than five — and the extra seconds are there for a reason. Slower heat distribution means the heating element reaches a more even temperature before air passes through the herb, which translates to smoother, more consistent vapor at up to 220°C.
WPC compatibility is built into the design, not an afterthought. Attaching it to a glass water piece drops the vapor temperature further and adds filtration. No battery, no charger, no app — just a torch and the device. For experienced butane users who have already settled on this style of vaporizer, the absence of electronics is a feature rather than a limitation.
One-year warranty covers manufacturing defects. The Convex 1.0 suits people who want a reliable convection butane device without the brand recognition premium of some of the larger names in the category. It rewards patience during heat-up and technique during draws — short, steady pulls extract more than fast aggressive ones.

Convection principle
Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporization at controlled temperatures releases über 95 % of the desired active compounds, while combustion by-products are largely avoided. Source: PubMed 16637053
Materials and craftsmanship
Technique and learning curve
Flavour and comparison
Yes, when a high-quality jet lighter is used correctly. The flame does not touch the material directly. Butane burns cleanly into CO2 and water.
The learning curve is steeper than with electric devices, but it becomes intuitive after a few sessions. For many people, the variable flavour is part of the appeal.
