The biggest practical difference is price tier: the Boundless Terp Pen sits at $25 while the Modul is $350, a gap of about $325 that puts them in different buying brackets.
Boundless Terp Pen is the cheaper option at $25 compared with $350 for the Modul, about $325 less. Live retailer pricing can shift, so confirm before buying.
Boundless Terp Pen uses ceramic & stainless steel coil heating, while the Modul uses conduction. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
Boundless Terp Pen controls heat with draw-activated, while the Modul uses digital. Modul gives you finer per-degree control.
Boundless Terp Pen is the better pick if low-profile use matters. It's tagged as stealth or pocket-friendly in our database, while the Modul is more conspicuous in hand and harder to keep out of sight.
Modul charges over USB-C; the Boundless Terp Pen uses a Micro USB port. USB-C means one fewer cable to keep around if your phone and laptop already use it.
