Stündenglass Gravity Infuser vs Dr. Dabber Switch²: UK Head-to-Head

The Stündenglass Gravity Infuser Classic and the Dr. Dabber Switch² both sit on a table, both push what you draw through water, and both cost serious money. Beyond that, they’re built on opposite ideas. The Gravity Infuser is a 360° rotating glass-and-aluminium piece with no battery, heater or circuit board: water and gravity do the work. The Switch² is an induction-heated electric rig with a temperature sensor, heating modes, an app and a rechargeable battery.

So this is a head-to-head between two very different machines, not a test of which one is “better” at the same job. We go round by round through how each works, heat and power, session style, cleaning, what’s in the box, warranty, and where to check price and stock. Every product figure comes from the manufacturers: Stündenglass’s own product pages and FAQs, and Dr. Dabber’s Switch² product page and Knowledge Base. We’ve checked our own listings against the same pages.

The short version

• Stündenglass Gravity Infuser Classic: a non-electronic gravity infuser. Stündenglass lists it for mixology, culinary, hookah and aromatherapy use, and says it works with dry material, concentrates and hookah setups. You light material in its bowl, or connect another device through a 14mm male joint, and rotate the unit to fill and push out the top globe. 10-year warranty.
• Dr. Dabber Switch²: an electric concentrate rig that heats a 20mm quartz insert by induction, from 250–650°F, in 5–20 seconds. Up to 30 heating cycles per charge, USB-C pass-through charging, 2-year warranty.
• The real choice: no electronics and a gravity-hookah style session, or set temperatures, no open flame and push-button heating.

Round 1: how each one works

Stündenglass Gravity Infuser Classic

Stündenglass calls the Gravity Infuser a “360° rotating glass infuser” that works through “cascading water displacement, opposing airflow technology and the natural force of gravity”. You fill the bottom globe with water, light material in the bowl and turn the unit over. As the water drains, smoke is pulled into the top globe through the built-in percolation; rotate it back and the smoke is pushed out through the mouthpiece. It is a patented design, and Stündenglass describes it as “a complete set that includes an aluminum bowl kit and a glass liner” that can also connect to any smoking or vaporisation device with a 14mm male joint.

Dr. Dabber Switch²

Dr. Dabber describes the Switch² as using omnidirectional induction heating, so its insert “heats up evenly from the sidewalls and the base at the same rate”. A patented integrated infrared sensor reads the insert temperature. The 20mm quartz insert comes already installed (a sapphire insert is sold separately), and because the heat goes into the insert, Dr. Dabber says there are no atomisers to fail.

Round 1 verdict: the Gravity Infuser is mechanical: water, gravity and your own heat source. The Switch² is a self-contained electric heater. Which is better depends on whether you want electronics at all.

Round 2: heat and power

The Gravity Infuser has no heater, no temperature control and nothing to charge. That means no battery to wear out, but also no way to set a temperature: heat comes from what you light in the bowl or from the device you connect at the 14mm joint.

The Switch² is all about controlled heat. Dr. Dabber lists a 250–650°F range (about 121–343°C), set in 1° steps in the app, a 5–20 second heat-up depending on the setting, and three dynamic heating modes on the product page (Descent, the default, plus Ascent and Steady). The app adds Hill, Valley and Custom. Power comes from LiFePO4 battery cells with over-voltage, over-current, under-voltage, over-temperature, short-circuit and reverse-polarity protection. Dr. Dabber quotes up to 30 heating cycles per charge, with USB-C pass-through charging and 60–90 minutes for a full charge. Its Knowledge Base adds that higher heat settings, longer hold times and brighter LEDs drain the battery faster.

Round 2 verdict: the Switch² wins on control and convenience; the Gravity Infuser wins if you want no battery or electronics at all.

Round 3: session style

A Gravity Infuser session is a ritual. Fill the bottom globe up to the top of the visible glass, rotate the unit almost all the way, light the bowl, and let the draining water draw smoke into the top globe. Then either draw from the unit or rotate again so the smoke is pushed out to you, which Stündenglass calls contactless consumption, through the 45° adjustable mouthpiece. The included 3ft silicone hose is there for direct draws. Stündenglass also describes cold-smoke finishing of food and drinks, with smoke pushed through the hose into a beverage cloche.

A Switch² session is push-button. Fill the glass attachment with water just above the perc holes, choose a temperature and heating mode, wait 5–20 seconds, load with the Drop heated loading tool and draw through the glass. Dr. Dabber recommends a cool-down of about 20 minutes after three or more consecutive heating cycles, as the top and back of the unit can get warm.

Round 3 verdict: the Gravity Infuser is a showpiece, social, hookah-style experience; the Switch² is quicker, repeatable and controlled.

Round 4: cleaning and care

From the Stündenglass FAQs:

• Clean only with water and isopropyl alcohol, or soap and water. Abrasive cloths and other cleaning agents can permanently damage the anodised and painted finishes, and alcohol can damage painted logos.
• Quick clean: empty the water, add ½–1 inch of isopropyl alcohol, refit the top globe, rotate until clean, then drain and rinse with clean water. Clean inside the valve via the magnetic bowl intake adapter end cap and rubber plug.
• If it gets hard to rotate, clean it straight away: build-up on the valve seals can make it stick and eventually tear them. A deep clean involves removing the globes, upstems and mouthpiece elbow.
• Don’t remove the bottom globe from the bottom side when it is full of water.

From the Switch² Knowledge Base:

• Swab the insert after every session, first with a dry cotton swab, then with one dipped in isopropyl alcohol while the insert is still warm. Never remove the insert while it is hot, and never torch it.
• Clean the glass attachment by shaking it with isopropyl alcohol (91% or higher recommended), rinse with warm water and air-dry fully.
• Remove the glass by resting both hands on the crown and pushing up gently from the bottom with your thumbs. Never pull it off by the mouthpiece.
• Do not use isopropyl alcohol on the outer shell.

Round 4 verdict: the Switch² needs a quick swab after every session; the Gravity Infuser needs regular valve and seal cleaning to keep it rotating smoothly. Neither is low-effort if you neglect it.

Round 5: in the box and warranty

Stündenglass Gravity Infuser Classic (Stündenglass’s list): anodized aluminum frame, borosilicate glass globes, silicone hose assembly, infusion chamber assembly, cleaning kit, sticker set and a reusable craft box with handle. Stündenglass backs it with a 10-year warranty; check its terms for the details.

Dr. Dabber Switch² (Dr. Dabber’s list): Switch² vaporizer, Drop heated loading tool, glass attachment, carb cap, USB-C charging cable and charging adapter. Dr. Dabber gives a 2-year warranty on the battery, charger and electrical components.

Round 5 verdict: the Gravity Infuser’s 10-year warranty is far longer. That’s partly because it has no battery or electronics to wear out.

Round 6: price and stock

Prices and stock change, so we don’t quote them here. Both were in stock when we wrote this guide; check our Stündenglass Gravity Infuser Classic and Dr. Dabber Switch 2 listings for the current price and availability before you order.

The verdict: which one is for you?

• Choose the Stündenglass Gravity Infuser Classic if you want a statement tabletop piece with no battery, charging or electronics, contactless gravity-hookah style sessions, the option to connect other 14mm devices, mixology and culinary smoke uses, and a 10-year warranty. Be ready to clean the valve seals regularly.
• Choose the Dr. Dabber Switch² if your focus is concentrates and you want set temperatures, no open flame, a 5–20 second heat-up, app-based heating modes and USB-C charging. Accept a battery, a shorter 2-year warranty and swabbing the insert after each session.
• Don’t treat them as substitutes. They do different jobs: one is a gravity water-filtration infuser, the other a temperature-controlled concentrate e-rig.
