Glass versus stainless steel: what the material changes day to day
Both devices work the same way. You fill the chamber, put the Captive Cap on, hold the flame to the cap and draw once it clicks. The difference starts with the body. The G3 is a glass UniBody in which tip and midsection are a single piece, with a built-in glass screen and a three-sided outer shape that keeps it from rolling off the table. The manufacturer describes it as the entry point for anyone trying DynaVap or dry-herb vaporizers for the first time who wants a complete device at a low price.
The M 7, according to the manufacturer, is made entirely of stainless steel. Its tip has no cooling fins any more but more mass: that keeps heat in the chamber longer after the click and is meant to allow strong single draws, while the tip passes up to 20 per cent less heat to the stem, which stays cooler in the hand. A reworked tip geometry is meant to spread heat evenly, and the new Captive Cap fit lets more air through the chamber than earlier M models. These are manufacturer claims, not our own measurements.
For longevity the material decides. Stainless steel shrugs off drops and heat, glass can break. DynaVap draws the line itself: functional defects of the M series are covered for life, glass stems are excluded and only protected by the 90-day return on direct purchases. A G3 is therefore not a device for the next decade but a cheap way in, and a replacement does not cost much.
Chamber and dosing: 0.05 g against 0.1 g
The G3 chamber holds 0.05 g, and the manufacturer markets it as microdose-ready. The M 7 holds 0.1 g and can be reduced by half with the “Adjust-a-Bowl” feature, so it covers the G3 range as well. If you mostly vaporize small amounts, the G3 gives you the right chamber size with nothing to adjust. If you want to switch between a short draw and a full bowl depending on the occasion, the M 7 has both settings in one device.
Heat source: a flame for both, induction only for the M 7
A torch lighter heats both devices up to the click. For the M 7 the manufacturer recommends a butane torch or an induction heater for the best flavor. For the G3 it advises against induction heaters because of the glass construction, including its own model. If you want to heat without a flame, you need the M 7. Which heaters fit which DynaVap is covered in the induction heater comparison; how to control flame, click and airflow is explained in the DynaVap technique guide.
Accessories and upgrades: closed system against modular kit
The G3 is a closed system. According to the manufacturer, caps (standard, Low Temp, Perforated, Cap Armor) and the DynaStash, SlimStash and SlingStash storage fit; tips, condensers, dosing capsules and the DynaCoil do not, and the UniBody needs no condenser. The glass body is not tapered, so it does not sit in a water pipe.
The M 7 is the modular kit of the M series: tip, stem, condenser, mouthpiece and cap can be swapped individually, dosing capsules fit the tip, and the 10 mm joint plugs into common water pipes. You set the airflow through the new airport and the “Pivot” rocker. If you want to add a different tip later, a longer version such as the M 7 XL or more accessories, the M 7 keeps you inside the system; which parts belong to which device is shown in the DynaVap accessories overview, and tips and caps are compared in which tip suits you.
Box contents and starting cost
In the manufacturer’s shop the G3 costs 35 USD and the M 7 89 USD (as of 1 Nov 2026). The box contents differ: the M 7 ships with a tin, a cleaning tab and an empty single-flame torch lighter. The G3 includes the torch and the cleaning tab only in its US version; the international version comes without. European retailers put their own kits together, so the box contents of the individual offer decide whether you still need to add a lighter and butane. In the price comparison you will find the G3 from 31.45 € incl. shipping and the M 7 from 71.98 € Code VAPOCHECKER10 · incl. shipping, each including shipping to your country.
Who should choose which device?
DynaVap G3: for a first contact with the click principle, for small amounts and for anyone who wants a complete device at the lowest price in the range. You go without a water pipe, induction heating, dosing capsules, upgrades and the lifetime warranty.
DynaVap M 7: for anyone who intends to keep and build on the device. Stainless steel, swappable parts, a chamber that halves, a water-pipe joint, induction as a second heat source and the lifetime cover for functional defects are what the extra money buys. If you are going to buy the M 7 anyway, there is no need to pass through the G3 first.
