The Puffco Peak Pro is a countertop e-rig with a built-in glass water chamber, app control, four temperature presets, and a session-style draw that pulls like a small bong. The Puffco Proxy is a modular pipe-format e-rig where the heating base detaches from interchangeable glass attachments, allowing the same atomizer to be used with traveler stems, art glass attachments from artists in the Elbo Artist Collection, and standard Proxy glass attachments. In daily use, Peak Pro buyers prioritize draw volume, water filtration, and the most polished out-of-box experience with no glass-matching decisions to make. Proxy buyers prioritize modularity, portability, and the ability to mount the heating element to multiple glass formats including heady artist work that displays well between sessions. Both run the same temperature precision and similar atomizer technology, so the vapor quality is comparable. Choose Peak Pro for a stationary session rig that does not need accessory swaps; choose Proxy for travel, glass customization, and the option to grow the setup with art glass over time.
