Background

The Solo 2 by Arizer is an upgraded version of the Solo vaporizer that was released in 2011. It’s a dry herb vape that delivers tasty and satisfying vapor. It mostly retains the look of the previous model but it has an OLED screen and three buttons on the front. This allows users to precisely set the temperature, as well as change some of the options like the screen brightness, auto-shutoff countdown, and the volume of the beep indicator.
What’s In The Box

The kit comes with everything that you need, plus a few things that you’ll find useful:
- Solo 2 Vaporizer – It has two different color variants which are the Carbon Black and Mystic Blue.
- Borosilicate Glass Stems (aka Aroma Tubes) – It has two different sizes: 90mm and 110mm.
- Glass Aroma Dish – This is for using aromatherapy herbs such as lavender (which is also included in the kit).
- Stainless Steel Stir Tool: This can be used to stir the herb in-between session to further vape the herb efficiently. And also to empty out the oven at the end of the session.
- Filter Screens – There are four filter screens that are included in the kit that you can use to keep the dry herb in place.
- Carrying Case – You can use this to store the unit and the aroma tubes when you’re traveling.
- Wall Charger – Unlike some vapes that use a Micro-USB, the Solo 2 comes with a proprietary charger that plugs into the outlet.
- User Manual
Additional Accessories

There are a variety of different accessories available for the Solo 2 and it’s also compatible with the accessories from the original Solo (except for the exotic charging stands since they changed where the charging port is located). The most interesting accessories are the various mouthpieces:
- Curved Mouthpiece – This mouthpiece curves at the top and allows users to vape without having to hold the Solo 2 directly below them. In my opinion, this is the best mouthpiece for Solo 2 and it would have been nice if it was included in the kit.
- Tipped Aroma Tube – This mouthpiece has a tapered opening that feels more natural to inhale from. This allows users to inhale less vapor during each draw.
- Frosted Glass Tube – This is the accessory that you need if you want to attach the Solo 2 to a water pipe.
Design & Features

The Solo 2 is 4.5″ tall and 1.75″ wide which is the same as the original Solo, but Arizer redesigned the Solo II by taking .25″ off the bottom and .375″ off the top. This makes the Solo 2 easier to hold and feels much nicer in your hand. It’s still not pocket-friendly but the included carrying case makes it easier to carry around while you’re traveling or taking a hike.
Full Digital Session Control

This is the most notable change made to the Arizer Solo II. Instead of having seven temperature lights and 2 buttons, it now has a circular menu pad and an OLED screen that displays necessary information like the temperature setting, battery life, and other options. With these changes, you have full control over:
- Temperature: You can precisely set the temperature that ranges from 122°F-428°F. It is adjustable in one-degree increments.
- Auto-Shutoff Timer: You can adjust this feature from 5-15 minutes.
- Volume Indicator: It can be turned down or all the way off.
- Brightness: The LED display can be adjusted to high, medium, or low.
- Start-Up Timer: You can set the length of press required to 4, 6, or 8 seconds to turn on the device.
Most advanced vapes have a smartphone app that you need to download in order to precisely set the temperature and adjust any other similar settings as mentioned above. It’s great to have access to these features directly from the vape without the need for a cumbersome smartphone app.
Better Airflow

First, let’s understand what is draw resistance and why lower means better. Draw resistance affects how hard or how easy you need to take a hit from the mouthpiece. A strong draw resistance requires slow and longer draw, while a vape with low draw resistance requires less effort which you can either take a slow or fast draw. Regardless of whether you’re a beginner or an expert vaper, you should always opt for vapes with lower draw resistance since it’s easier to inhale the vapor.
The previous Solo had poor draw resistance which affected its overall performance. On using the Solo 2, that’s not the case, it has a better airflow that provides a smoother and less restricted draw. There are also factors that somehow affect the draw resistance of the device: how fine you grind your herb and how tight you pack the herbs into the oven. So make sure you use a fine quality grinder like the SLX Grinder V2.5 and pack the herbs not exceeding 0.15g to make sure you get the most of the vapor from the Solo 2.
Fast Heat-Up Time

Arizer Solo 2 is considered as one of the fastest vaporizers when it comes to heat up time. It takes about 30 seconds to reach the vaping temperature between 380°F-400°F. The reason for that is the whole bottom part of the device is a big battery that has a lot of power available. It supplies the heating oven an enormous amount of energy while preventing the herbs from combusting.
Aside from the fast heat-up time, the Solo 2 features a ceramic heating element that uses a hybrid heating method that utilizes both convection and conduction heating. This helps with the flavor of the herb since it’s more efficiently vaped.
Long Battery Life

Arizer Solo 2 has an impressive battery that can withstand up to three hours of constant use, which could translate into multiple sessions over several days without the need to catch a charge. This is insanely big compared to standard vapes that typically last an hour of vaping. It takes up to three hours to fully recharge, and the Solo 2 supports pass-through charging so you can continue vaping even if it’s charging up.
Perfect Oven Size for Solo Sessions

The Solo 2 vaporizer is named ‘Solo’ since the oven size is perfect for solo sessions. It can hold up to 0.15g of dried herbs which is decent enough for beginners to take a couple of hits before starting another session. As for me, I use this to vape with my evening cup of tea in my backyard and get the right amount of herbs for the rest of the night.
However, if you’re a heavy user or are planning to use it in a party amongst friends, the bowl size won’t be enough. You may need a vaporizer with a bigger bowl size that can hold up to 0.3g-0.5g. One of the few examples is the Utillian 722 or the Zeus Arc GT.
How To Use

The Solo 2 is very easy to use since you just need to stick the end of the mouthpiece into your herb and then stick it into the oven. This vaporizer has one of the quickest filling procedures out there. Yes, the overall plainness of the design might not be too exciting but hey, it’s sturdy and functions well.
To use it you need to:
- Place the bottom end of the glass stem into your herb, tap the end to create a small space between the herb and the opening, and then place the tube into the herb chamber.
- Hold down the menu button and the up button simultaneously to turn on the device.
- Press the up-down buttons to choose the temperature in 1° increment or hold them down to select the temperature in 10° increments.
- Inhale from the mouthpiece when heating is complete.
Other Settings: Use the Menu button to navigate through different settings (Temp settings, Audio/Beep, Power-On Delay, Shut-Off Timer, and Brightness) and use the Up and Down buttons to adjust them.
Cleaning And Maintenance: The things that you need to clean are the glass stems. You can easily clean them with the included cleaning tool to scrape out any herb residues from inside of the glass stems. If you want to thoroughly clean them, you can soak them in isopropyl alcohol for 5 minutes, and then rinse them out with hot water.
Performance & Vapor Quality

Arizer manufactures different types of dry herb vaporizers whether portable or desktop vapes such as Arizer Air 2 or Arizer V Tower that provide great value for its price. The Solo 2 is no different. Aside from the quick loading, it heats up extremely fast! The thing I liked about the Solo 2 is it doesn’t get hot after extended use unlike from smaller vapes.
As far as vapor quality, the Solo 2 produces smooth, pure, and cool vapor thanks to the hybrid heating system and the glass stems. Speaking of which, the glass stems are made of borosilicate glass which is heat-resistant and durable. It helps to keep the vapor cool and preserves the flavor of the herbs.
The glass stems have three functions: mouthpiece, vapor path, and where you load your botanical material. The longer mouthpiece is better for keeping the vapor cool because of its length. While the vapor feels warm and intense with the shorter mouthpiece. So keep that in mind when deciding which mouthpiece to use.
Bottom Line

Overall, Solo 2 boasts improvements in every front from the previous model-which proved itself a valuable vaporizer, and established Arizer as a major player in vape manufacturing. It’s smaller (just a little!), has a longer battery life, heats up quicker, and features precise temperature control. Yes, it can’t fit in your pocket but this big guy produces excellent vapor quality that can accommodate both beginners and intermediate users.
Due to its size and durability, this is a great vaporizer for keeping at the house to share with guests or packing away for hikes and camping trips. It could have been better if it had haptic feedback and a session timer display. Other than that, this is a perfectly-designed vape worth under $200, and possibly one of the best dry herb vaporizers on the market. If you want a portable vaporizer that fits in your pocket with a replaceable battery, I highly recommend the Arizer Air 2 or if you want a bigger bowl size, the Crafty+ is right for you.
