Comparison FAQs
What is the biggest difference between the G Pen Pro and the RiO?
The biggest practical difference is heating approach: G Pen Pro runs convection while RiO runs conduction. That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
Which is cheaper, the G Pen Pro or the RiO?
G Pen Pro is the cheaper option at $90 compared with $150 for the RiO, about $60 less. Live retailer pricing can shift, so confirm before buying.
What's the difference in heating between the G Pen Pro and the RiO?
G Pen Pro uses convection heating, while the RiO uses conduction. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
Can I set custom temperatures on the G Pen Pro or the RiO?
G Pen Pro controls heat with modular - 3 stages, while the RiO uses manual. Both let you change temperature, just with different levels of precision.
How much flower do the G Pen Pro and RiO hold?
G Pen Pro lists a chamber capacity of ~0.25 grams; the RiO lists N/A.
Is the G Pen Pro or the RiO better for microdosing?
RiO is the better fit for microdosing in our database, typically thanks to a smaller chamber, finer temperature control, or both.
