The Haze Square is a quad-oven, full-convection portable vaporizer that features a sturdy aluminum casing, stainless steel chambers, and a silicone mouthpiece that hides in the vape device’s frame. The Square vaporizer consists of various parts. There is the materials tray with the four separate ovens, which holds either the herbs, concentrates or e-liquid within the frame.

The tray sits in the twistable lid that connects via a locking mechanism to the battery and heater section, which is the other crucial part of the vape device. The battery and heater section also hide the mouthpiece, the up/down buttons and the USB port for charging the internal battery.

Kit Contents

For anyone thinking of buying a Haze Square, or the new Haze Square Pro, Haze Technologies (makers of both) went out of business last year. There may still be some units out there but get them soon, as there will not be any more made.

The Haze Square vaporizer, being an innovative, portable and versatile device, comes with a lot of goodies in the box, which is also quite significant as it has a lot to hold. The design and presentation of the Haze Square were on par with the device’s performance as a convection vaporizer.

Here is what vapers should expect to find in their Haze Square box:

  • Haze Square Vaporizer
  • 4 Material Pods
  • 2 Stainless Steel Concentrate Pads
  • 2 Silicone Lids
  • Mouthpiece
  • Wall Charger
  • USB-C Charge Cord
  • Cleaning Tool
  • Material Tool
  • User Guide

A Deep Look of the Haze Square

The Haze Square vaporizer does not depart much from its title, as it has a decidedly square, stout frame, with a single power/firing button in its center. The entire vaporizer measures 3” x 3” x 1.25” so it has a portable form factor, although it is a little bulky, but still lightweight at only 9oz. Despite having a lot of moving parts, it’s not hard to get a handle on using the Square, which we’ll get to later.

As the Haze Square is an on-demand vaporizer (meaning it creates vapor when the user presses the button), it does not use an OLED for users to set the temperature. Instead, the Square has five pre-programmed settings, which range between 320F-480F, which is the best range for these kinds of vapes.

Users can switch between these five presets with the up or down button on the device’s side.

Different colors represent each heating level:

  • Lowest – blue light – 320F
  • Mid-to-low – lighter shade of blue – 370F
  • Medium – purple light – 380F
  • Mid-to-high – lighter shade of red – 390F
  • Highest – red light – 430F

The Haze Square has an internal 2000mAh cell, and its large capacity does not mean it takes a long time to recharge. It should be mentioned that there are two versions of the Square, with only a few minor differences between them.

The Standard version uses a micro USB for the cell, while the Pro version has USB-C, which takes less time to charge. The Pro version also has a higher range, with its maximum being 480F, instead of the 430F for the Standard.

The Pro also has Bluetooth compatibility so that it can sync with a smartphone app for added customization. Aside from these differences, there is not much else that separates the two devices. Thanks to the unique port, the Pro can go from empty to full in only half an hour.

The time it takes for the micro USB port on the Standard to replenish the cell takes around 45 min, so there’s not much of a change. This port, for both versions, is on the outer portion of the square on the battery section.


Internally, the Square has a unique design. There are four individual material chambers. But to use solid or liquid concentrates, users have to insert one of the two stainless steel pads that come in the kit expressly for concentrates vaping, a common feature among the best convection vapes. The pads also work with e-liquids, according to Haze.

There is a locking mechanism on the opposite side of the power/firing button that users need to twist (until the line is horizontal) to release the latch. Once the two sides are apart, a small tab on the materials tray lets users take the tray from inside the lid.

The four chambers are all stainless steel. There are silicone lids that also come in the kit that can cover up an oven for use later, or as a portable, pre-filled pod. The way the Haze works is that the heating element on the opposite section, the cell section, lines up with a chamber, activates the heating coil.

The air heats up, and when a user takes an inhale the air rushes through the chamber, delivering the vapor to the user via the ceramic mouthpiece – aka convection heating. There is a clear, unobstructed vapor path, so the flavor does not get sullied.

The air starts heating up when the user presses the firing button. The heat-up time is minimal as it takes around five seconds for the device to vibrate to signal that it is ready. Vapers need to repeat this process whenever they take a hit.

And, of course, the grand design of the Square is its four-ovens. Once one chamber is exhausted, vapers need only switch to another chamber by rotating the device. There is a heater symbol on the battery section that lines up with the four different icons that symbolize the four separate chambers.

Users can switch between them even if they each contain different material. Because of the vaporizer’s versatile design, vapers can load any material into the chambers and have a combination of them inside the vape.

Vape Time

Getting the Haze Square vaporizer working is easy. The trickiest part should be loading the chambers, but it’s not that difficult once the tray snaps back into the lid. There are accessories that Haze Technologies used to sell to make loading more comfortable, but as the company went out of business, those accessories should be hard to find.

Anyway, once the chambers are loaded, users have to assemble the device, lock it into place, and click the power button three times to activate it. They can then take out the removable mouthpiece from its compartment, install it and then they can set the temperature via the up/down buttons near the mouthpiece.

Once they’ve set the device, they need to press and hold the firing button again to activate the heater. The total heat-up time is still, only a few seconds, around four to five, which is the best, as vapers get vapor immediately. The device vibrates when it is ready, and vapers can take their first hit.

Depending on the temperature set, the vapor quality varies from thin, and delicate to thick, and voluminous. The lower ranges from between 320F and 380F produce the most flavorful, but thinnest clouds, while the higher temperatures provide a mouthful of vapor with a robust and intense feel.

Switching between the chambers is also effortless. The chambers can hold around a quarter of a gram worth and seem to last for about four or five hits, for each bowl. Of course, the amount of hits depends on how long a person draws and how high the temperature is set.

A vaper could take one of two long hits, for a satisfying gulp of vapor or they could take four or five little draws to get the most out of the herb or concentrate. With four ovens to play with, a vaper can mix and match their strain, or rotate between different materials with ease.

The Vape-Off

The DaVinci IQ

The Davinci IQ is an herb vaporizer with a removable 18650 battery as its power source. It features ceramic zirconia throughout its build. The vapor path, which is also removable, is ceramic zirconia. The chamber is also ceramic zirconia. The IQ has two temperature control methods. There is a three-button control panel along the side of the unit.

The temperature range for the IQ runs from 250F to 430F. The IQ has what Davinci calls Smart Path heating, which is a collection of four heat ranges that a user can select, so the device stays within that range. The IQ is Bluetooth compatible, so users can sync their phone to the unit via an app and control the temperature or make other adjustments.

The Crafty

The Crafty is an herb and concentrates device made by Storz and Bickel, makers of the Volcano. The Crafty has a pre-installed heat setting that turns to 365F whenever a user activates the device. There is no OLED or adjustment buttons on the device, as the Crafty relies on its Bluetooth connectivity to allow for greater user control via a smartphone app.

The Crafty features a stainless steel and aluminum exterior, with a bottom-loading chamber. The Crafty also features a collapsible, and twisting mouthpiece on top of the device that swivels around. The device has an LED light to show when it is on and when the heating process is underway.

Pros and Cons


  • Unique and innovative design
  • Four material chambers for herbs, waxes, and e-liquids
  • Good temperature range
  • Fast recharging time
  • Good flavor production
  • Quick heat-up time


  • A lot of cleaning and maintenance
  • A lot of moving parts; it can break easily

Conclusion: The Final Word

Important: Haze Technologies is out of business. A few sites still have the Square and Square Pro for sale, but as the manufacturer no longer exists, don’t expect any customer service if the device is faulty, if it experiences problems or breaks.

The Haze Square vaporizer is a different take on what a vaporizer should look like. With its four-chamber design, it broke the mold, although it seems that that innovation wasn’t enough to keep the business afloat. The Haze Square still held up as a worthy entry into the dry herb game.

The vape’s performance never faltered, as it always managed to create stupendous vapor, both in terms of size and flavor. Switching between the temperature settings was smooth, and the device was responsive when the button was pressed.

The temperature range between the Standard and Pro was only minimally small, and the charging time between was also negligible with only a few minutes difference between them. Whether it was the Standard or Pro versions, there was not a lot to dislike about the device.

The maintenance and cleaning of the unit were more than others. As there are four chambers to dust off and wipe down, they should be cleaned after every session. The screens also need cleaning after every use to keep them clear. Keeping the Square vaporizer in good working order is the best way to ensure it always performs.

My way of understanding the significance of vaping came not only through the disruption of smoking but its effects on society as a whole. Now I bring people to vaping and bring vaping to people. I love using new gear, writing in-depth reviews and generally nerding out about vaping to like-minded people.
