Overview
The Haze Square Pro was a portable, battery-powered dry herb vaporizer manufactured by Haze Technologies (also known as Haze Vaporizers). The device was released circa 2017–2018, representing a significant departure from the company's earlier dual-chamber Haze V3 design. The Square Pro featured a distinctive square form factor and utilized a conduction heating method with swappable, pre-loadable bowl system — its signature feature being the ability to hold up to four individual bowls within a rotating tray, allowing users to switch between packed chambers on the go without reloading.
The device went through multiple development phases, with Phase 3 being the production version most widely distributed to consumers. The Haze Square Pro retailed for approximately $180 new. Haze Technologies ceased operations at some point between late 2018 and mid-2019, leaving the device without manufacturer warranty support, replacement parts, or firmware updates. A planned "V2" hardware revision was announced but never released.

Community Reception
Community discussion of the Haze Square Pro was relatively limited within the available thread data, with most surviving posts being marketplace listings rather than in-depth reviews. However, several observations can be drawn from community members' comments:
Positives:
- The multi-bowl rotating tray system was considered a genuinely innovative and practical feature, allowing users to pre-load multiple sessions and switch between them without any mid-session packing.
- Customizable temperature presets and LED color settings via firmware were appreciated, with one community member noting that the LED customization was "one of my favorite things about this vape."
- Battery performance was reported as reliable by at least one long-term owner who noted the "battery has been fine" over an extended period of use.
- When functioning properly, the device was described as a "fine working vape" that operated well without requiring firmware updates beyond initial setup.
Negatives / Concerns:
- The company's closure was a significant blow to the device's long-term viability. With no warranty support, no parts replacement, and uncertain availability of the firmware customization software, the device became an orphaned product. This was reflected in rapidly declining resale values — units that retailed at $180 were being offered for as low as $35 within roughly a year of the company's closure.
- Early production units (first batch) reportedly suffered from a seal issue that required the device to be sent back to Haze for repair. While the fix was described as quick and effective, it indicated quality control challenges during the initial rollout.
- The planned V2 hardware upgrade, which was offered as a free upgrade to existing owners, was never delivered due to the company going out of business.
Overall, the community's engagement with the Haze Square Pro appeared cautiously positive regarding the device's concept and functionality, but enthusiasm was tempered by the manufacturer's reliability issues and eventual closure.
Tips & Techniques
Loading:
- The Haze Square Pro's bowl system allowed users to pre-load up to 10 individual bowls (with the Adventurer accessory pack) for grab-and-go use. Community members took advantage of this by loading multiple bowls in advance for outings or extended sessions.
- Bowls were available with or without lids, offering flexibility in packing style.
- The included loading tray and cleaning tray were purpose-built accessories to streamline the process of filling and maintaining the small individual bowls.
Temperature Stepping:
- Users commonly configured their five temperature presets in ascending steps and would work their way up through the presets during a session. One community member reported using 320°F–340°F–360°F–380°F–400°F (160°C–171°C–182°C–193°C–204°C) as their preferred progression, while another configured 355°F–385°F–405°F–425°F–445°F (179°C–196°C–207°C–218°C–229°C).
Firmware & Customization:
- Temperature presets and LED colors were set via companion software, originally available for download. After the company's closure, users noted uncertainty about whether the software remained accessible and suggested sharing it via USB if needed. Users were advised to configure their preferred settings and leave the firmware alone if the device was operating satisfactorily.
Temperature Guide
Based on community-reported preset configurations:
| Temperature | °F | °C | Reported Use |
| Low / Flavor | 320°F–340°F | 160°C–171°C | Light, flavorful vapor; low visible cloud production |
| Low-Medium | 355°F–360°F | 179°C–182°C | Flavor-forward with moderate vapor |
| Medium | 380°F–405°F | 193°C–207°C | Balanced flavor and vapor production |
| Medium-High | 425°F | 218°C | Fuller extraction, denser clouds |
| High / Efficiency | 445°F | 229°C | Maximum extraction; less flavor, more clouds |
Two distinct temperature-stepping philosophies emerged among users:
- Wide range approach: 320°F to 400°F (160°C to 204°C) — favoring flavor and moderate extraction, with the top temperature still in a relatively moderate zone.
- Higher range approach: 355°F to 445°F (179°C to 229°C) — starting at a moderate baseline and pushing into higher extraction territory.
No single community-agreed "sweet spot" temperature was established in the available discussions.
Maintenance & Cleaning
Detailed cleaning procedures were not extensively documented in the available community discussions. Based on the information available:
- Haze Technologies provided a dedicated cleaning tray as an accessory, suggesting a structured cleaning workflow was intended for the individual bowls.
- Concave screens were used in the bowls and were available as replacement parts; keeping fresh screens on hand was advisable.
- The pick tool included in the OEM kit was presumably intended for clearing bowls and dislodging residue from the small individual chambers.
- General best practices for conduction vaporizers apply: regular cleaning of bowl surfaces and screens to prevent residue buildup, which can affect both flavor and airflow.
Common Issues & Fixes
Seal Issue (First Batch)
- Early production units from the initial manufacturing batch experienced a seal problem. At least one community member reported this issue and noted that Haze resolved it with a quick service repair, after which the device functioned without further problems. With the manufacturer no longer in business, users experiencing this issue on unrepaired units would need to attempt a DIY fix or source compatible sealing materials.
Firmware Software Availability
- Following the closure of Haze Technologies, the companion software for customizing temperature presets and LED colors became difficult or impossible to obtain through official channels. Community members suggested sharing the software via USB-C flash drive when selling or trading units. Users were generally advised to set their preferred configurations and avoid unnecessary firmware changes.
Orphaned Product Concerns
- With no manufacturer support, replacement coils, batteries, screens, and other consumable parts became finite resources. Community members selling units often noted the inclusion of extra coils, batteries, and screens as significant value-adds. Users who still operate the device should maintain a stock of spare parts when possible.
Accessories & Modifications
OEM Accessories:
- Adventurer Extra Pack: Included additional coils, an extra mouthpiece, an extra loading tray, and additional bowls (up to 10 total), expanding the device's pre-loadable capacity.
- Extra Battery: Removable and swappable; spare batteries were available and highly recommended for extended use away from a charger.
- Concave Screens: Replacement screens for the individual bowls.
- USB-C Flash Drive: Used for firmware updates and settings customization.
- Loading Tray / Cleaning Tray: Purpose-built accessories for bowl management.
- Bowl Lids: Optional lids for individual bowls, useful for pre-loaded transport.
Community Modifications:
No specific community-developed modifications or aftermarket accessories (such as third-party WPAs or custom stems) were documented in the available thread data. Given the device's relatively niche user base and the manufacturer's early closure, the aftermarket ecosystem for the Haze Square Pro was likely very limited.
Comparisons
No substantive comparative discussions between the Haze Square Pro and other vaporizers were found in the available community thread data. The device occupied a unique niche with its four-bowl rotating tray system, and direct competitors offering a similar multi-chamber portable design were uncommon in the market. The device's predecessor, the Haze V3, featured a dual-chamber design (supporting both dry herb and concentrate) but used a fundamentally different form factor and chamber arrangement.
