Review Summary


The Vexil is palm-sized portable that features a zirconia cooling system, magnetic mouthpiece, USB-C charging, four preset temperatures, and conduction heating technology. Its unique wide oven design brings draw resistance to near zero, further improving on the good vapor quality it delivers.


Since 2016, US-based brand Boundless Technology has been manufacturing and updating its product line. As opposed to releasing several new devices at every turn, Boundless has a select few that they run with opt to re-release them with better and more apt updates. Their CFC dry herb vaporizer was first released in 2018 and re-released as the CFC 2.0 (review) in 2019 and their popular Terp Pen was upgraded as the Terp Pen XL (review).

This is why it’s pretty exciting to see a new device from Boundless – the Vexil. A palm-sized dry herb vaporizer that features a zirconia cooling system, magnetic mouthpiece, USB-C charging, four preset temperatures, and conduction heating technology.

Compatibility: The Boundless Vexil is compatible with dry herb only. I tested the Vexil with Sour Glue CBD from InHemp and THC herb from my local dispensary.

Kit and Accessories

The Boundless Vexil comes in a small box, with all of its instructions printed out on the tri-fold flap that covers the device. The device kit itself doesn’t come with much, and rightfully so – it’s a compact vaporizer with a compact kit.

Here’s what’s you get:

  • Boundless Vexil
  • Cleaning brush
  • USB-C Charging Cable
  • Mouthpiece Screens (x2)
  • User Manual

Design and Features

At first glance, you’ll immediately notice the Vexil’s unique design. It actually looks somewhat like a remote for something and less like a vaporizer. While most devices are either pen-shaped and/or are rounded and minimalist – the Vexil is slightly flat, with several raised angles throughout its body. At only 154g, it’s a pretty lightweight device – but feels dense, solid, and balanced to the touch.

The main body casing is made of metal, which is quite new from Boundless since they are quite known for using plastic on their devices. It measures 10.8cm tall and 4.5cm in width – meaning that the Vexil is pretty portable and would definitely be concealable in your palm, and will fit any purse you place it in.

On the front of the device is a display with a flame graphic to indicate heating or temperature, and on the side are three small buttons, the power button, and two arrows for toggling through the 4 pre-set temperatures. The top portion of the device is an angular mouthpiece cover that sits on top of the smaller zirconia mouthpiece. Both of which are connected to the device by strong (and snappy) magnets.


The Boundless Vexil is powered by an internal 1800mAH battery which lasts 6 sessions on average. While that’s relatively average battery life, there isn’t a lot to worry about in case the Vexil does run out of juice. The Vexil charges via USB-C and goes from 0 to fully charged in 45 minutes. USB-C is a lot more stable than the outdated micro-USB and is just as easily available and accessible everywhere.

How to Use

The Vexil may have a somewhat complex look, but using the Vexil, however, is about as straightforward as it gets.

  1. Remove the magnetic mouthpiece and mouthpiece cover
  2. Load the herb into the oven
  3. Snap the mouthpiece back into place
  4. Click the button five times to turn the device on
  5. Press the up and down buttons to cycle through the four temperature settings- Green: 360F(182C), Purple: 380F(193C),  Blue: 400F(204C), and Red: 420F(215C).
  6. Wait for the device to reach the temperature. The light will flash as it’s heating and then become solid when it’s ready.
  7. Draw slowly and enjoy!

To turn the heater off at any time during a session, hold down the power button for 3 seconds and hold it for another 3 seconds to get it going again. Once a session is complete, the device then goes into sleep mode to save power, restart the heater- hold the power button again for 3 seconds. To turn the Vexil off, click the power button 5 times fast.


Boundless Tech calls the Vexil a “Compact Powerhouse” and it’s not hard to see why. It’s just as packed under the hood as it is design-wise. The Vexil has a ceramic chamber that holds .5g of herb and uses convection heating to get the most flavorful vapor possible.

The Vexil is also the first Boundless device to have zirconia pieces – namely the zirconia spiral cooling air path, and the mouthpiece. Zirconia is an advanced, neutral material that cools down vapor and keeps it pure. Within the zirconia air path is a helix insert placed in for good measure – since without it, the Vexil has a pretty short airpath. Meaning the vapor doesn't have enough time to cool down while traveling from the oven to the mouthpiece. The helix insert extends the airpath internally so that the vapor cools before exiting the mouthpiece.

All things considered, the Boundless Vexil performed well and provided great vapor quality. I’d like to particularly point out the wide oven which allowed for pretty low draw resistance. Most deeper ovens sometimes result in tougher milkshake draws and the Vexil’s oven design eliminates that issue entirely. Drawing from the Vexil is smooth and easy, and the vapor quality it delivers is among the best in its price point.

Bottom Line

With that said, the Vexil is intended to be a point & shoot vaporizer and it definitely is. As a long-time-vaper though, I’d have preferred that there was precise temperature control. While the four presets are well-calibrated to get high efficiency, I always prefer granular control over the temperature.  

Other than that small detail, I’d definitely say that its construction and design are unique for its class. The Vexil does extremely well for its price – and you can even shave off 15% off your bill with our coupon code TVG15. If you are looking for a second device or are a new vaper looking for your first, I highly recommend the Vexil.
