When you have two compact vaporizers side by side, put them on equal footing. First, compare battery capacities—write them down. Next, look at the heating element material. If one uses ceramic and the other uses metal, the ceramic one will likely taste better. Finally, check cartridge compatibility: a 510-thread is standard, but some devices only work with proprietary pods, which limits your options.

Don't get distracted by color options or LED lights. Those don't affect performance. Instead, ask: which one will last through a movie without charging? Which one will preserve the flavor of my oil? Those answers will steer you right.
