Transient Mist Flow Pro

How much does the Transient Mist Flow Pro cost?

Transient Mist's site lists the Flow Pro at $236 for the battery-free version and $248 with a Molicel 18650 battery, in black, with October 10, 2026 as the launch date. The prices are shown with a dollar sign, but the store's checkout is set to Australian dollars, so check the currency before paying.

Where can you buy the Flow Pro?

At launch, the only seller is Transient Mist's own website. Canadian retailer Soothing Vapours has said it tested prototypes and expects its first stock in mid-October 2026. Transient Mist's site also lists several US and UK stores as partners, but VGoodiEZ, one of them, has said publicly that it has no connection with the brand, so check with a store directly rather than relying on that list.

Is Transient Mist a legitimate company?

It is too early to say. Transient Mist has not named the company or people behind it, and the only contact details on its site are an email address and a Hong Kong WhatsApp number. Its website went live with pages left over from Mad Heaters' Tempest 2 manual, store policies that contradict its product pages, and a partner list that at least one named store disputes. Until independent reviews and established retailers appear, treat it with caution and only pay with a method that offers buyer protection.

Is the Flow Pro convection or hybrid?

Transient Mist does not put a label on it, but its description fits a hybrid. The foil heater warms the air drawn through the herb, and the aluminum bowl holding the herb absorbs heat from the heater, spreads it evenly and, in Transient Mist's words, acts as a buffer against temperature swings as you draw. That combination of hot air and a heated bowl is why we list it as a hybrid, while Transient Mist calls the T Vibe full convection. Our guide to convection vs conduction explains the difference.

Can the Flow Pro use dosing capsules?

Yes. Transient Mist says the chamber takes either loose herb or a pre-filled capsule, but it has not said which capsule size or brand fits. Our guide to dosing capsules covers why people use them.

What battery does the Flow Pro use?

A removable 18650. The product page lists a Molicel P30B rated at 3000mAh, while the manual names a Molicel P28A rated at 2800mAh and 35A continuous. For the battery-free version, the manual says any cell you buy must handle at least a 10C discharge. Twist off the bottom cap to swap it and fit the cell with the positive end facing down. Transient Mist has not published a sessions-per-charge figure. Our guide to vaporizer battery life covers caring for removable cells.

What temperatures does the Flow Pro use?

Session mode runs from 40°C to 220°C (104°F to 428°F) with a countdown of 100 to 500 seconds, and on-demand mode runs from 40°C to 240°C (104°F to 464°F) for as long as you hold the button. You can switch the display between °C and °F. Our temperature guide explains what different settings change.

Can the Flow Pro be used with a water pipe?

Yes. It comes with 14mm and 18mm water pipe adapters, and our guide to dry herb vaping with a water pipe explains how to set one up.

How do you calibrate the Flow Pro?

Transient Mist suggests calibrating after 2,000 to 3,000 heat cycles, or sooner if vapor or flavour changes at the same settings. Deep clean it first and let it cool for at least 30 minutes. Then hold the power and plus buttons together until it vibrates, press power three times to open calibration, and press it once more to calibrate automatically. The manual says a TCR value of 96 or 97 is normal. Press power five times to turn it off.

What warranty does the Flow Pro have?

The manual gives a 24-month limited warranty from the purchase date. It excludes batteries, O-rings, screens and glass mouthpieces, and it is void after unauthorized disassembly or modification, with the manual singling out the five main fastening screws as ones not to loosen. Transient Mist's store terms are stricter: they say it does not accept returns or give refunds on new and unused devices, does not repair damaged devices or supply spare parts, and only replaces damaged, incorrect or incomplete orders reported to hello@transientmist.com within two days of delivery.
