The Utillian brand of portable vaporizers has released some highly popular devices, and maybe the most popular was their 420 model. An updated sibling version of the 420 has recently been made available, the 421. The 421 dry herb portable vaporizer comes with some similar features that users loved, such as a glass mouthpiece for smooth, tasty rips, a digital display, and a ceramic heating chamber for easy maintenance. There are some interesting differences on the 421 that we didn’t see on the 420. Do the upgrades on the 421 perform better than its sibling? Read on and judge for yourself.

Heating, Aesthetics & Discreetness

The Utillian 421 uses conduction heating and heats up in about a minute. Of course, there are devices out there that heat up faster than that, but for what it is; the 421 will be ready for use relatively quickly. The 421 is very discreet, and is compact enough that you to get a tasty vape rip in a manner that won’t draw too much attention. The unit fits nicely in your palm and in any pocket. Its look and feel is similar to a small flask. The design and the glass mouthpiece resemble a lot of e-cig mods, which adds another layer of discreetness. The 421 looks sleek as well, which an attractive black anodized aluminum finish.

What’s Included With the Utillian 421

Straight out of the box, the Utillian 421 obviously includes device itself. In addition, you also get a USB charging cable, extra screens, and a tool for packing your dry herbs. The tool is handy for making sure that you don’t spill any precious material and allows you to pack everything in the chamber well enough to ensure proper airflow. Your 421 will also include a useful shield that protects the glass mouthpiece from overheating. The 421 will also be protected by a direct warranty of 1 year.

How the Utillian 421 Works/ Ease of Use

Using the 421 is about as easy as they come. There is only one button on the device, and to turn it on or off, you simply press the button 5 times and wait a minute for it to heat up and be ready. The unit has 6 preset settings ranging from 180°C/356°F -190°C/374°F – 200°C/392°F – 210°C/410°F – 220°C/428°F – 230°C/446°F, which cover a pretty wide range of temperatures. For what it’s worth, the 420 from Utillian offers a good amount of choices in the temperature flexibility department. To switch temperatures, just hold down the button and let it do its thing. The digital display on the unit is bright and easily visible and simple to understand. You’d be hard pressed to find a device that is simpler to use than the 421 – no frills, no fancy bells and whistles, just a straightforward unit with solid performance.

Vapor Quality of the Utillian 421

The combination of a glass mouthpiece, a ceramic chamber and a new airflow valve means that the 421 produces similarly decent vapor quality that the 420 did. The airflow valve on the 421 does make a noticeable difference in the amount of vapor you will produce with the device, but the taste, flavor and smoothness of the 421 is basically the same as its predecessor. The Utillian 421 has a 2300mah battery that will last you about an hour of continuous use.

Cleaning & Maintenance of the Utillian 421

Similar to its predecessor, the ceramic chamber of the 421 is easily cleaned and maintained. We recommend giving the device a thorough clean after every charge or two. This will ensure you remove any lasting debris and deliver high quality rips.

The Utillian 420 VS The Utillian 421 Comparison

And now, the part you’ve all been waiting for… What are the differences between the Utillian 420 and the Utillian 421? For starters, the 421 has a new airflow valve at the bottom instead of the storage compartment, like we previously mentioned, and also has 6 preset temperatures instead of 4 like on the 420. The 420 comes with a boost feature that increases each of the 4 temp settings by 5 degrees, so technically the 420 does have more temperatures overall. But the 6 presets on the 421 offer a wide array of temperatures that don’t disappoint. As we’ve said, both the 420 and the 421 have a glass mouthpiece and a ceramic chamber that deliver fairly high quality vapor.


  • The Utillian 421 has a ceramic chamber for easy cleaning and maintenance, which also means fairly even heating and solid vapor production
  • Glass mouthpiece means vapor rips that are pretty tasty and flavor rich
  • New airflow valve at the bottom of the Utillian 421 delivers smooth draws and some decent sized clouds
  • 6 temp settings with a wide array gives you some flexibility
  • Bright, vibrant digital display that is easy to read and understand
  • The value that you get at this price point is impressive and you can’t really beat it
  • Protected by a direct 1 year warranty


  • The Utillian 421 is only compatible with dry herbs, no waxes or oils
  • The device has 6 preset temperatures, which should be plenty for newbies, but might be viewed as a bit limiting for experienced vape users. Would’ve been nice to see a precise digital temperature control.

Bottom Line

The Utillian 421 is a well-built, easy to use, durable, discreet and attractive portable vaporizer that delivers solid vapor production and quality. It is a great choice for any newcomer to the world of vaporizers, and experience vape users could most certainly do worse if searching for a second device. If you’re looking to leave combustion behind in favor of vaporization, but don’t want to break the bank in the process, the Utillian 421 might just be the device for you.

    Lit it hits I love the name 420 421 haha we smoke every day after school at 4:20 so the name 420 is perfect for what we want. The best strain to vape thru this I think is AK-47, hits like a truck and tastes so stinky lol

    As a medical cannabis patient I felt inclined to throw in my own Utillian 421 review to help out any others in the same situation as I. Overall I think it’s a good vaporizer for a budget however for my amount of usage and requirements it falls short.
    The battery life is alright but I often ran out halfway throughout the day and often wished it had a removable battery. As well as that I found the flavor to drop off after hit number 6 or 7 and I could also swear the performance after a few months wasn’t as good even with religious cleaning. I have a friend with a different Utillian vape which he swears is better however I have not been able to try it out yet.
    I’m currently looking for a different weed vaporizer and willing to spend a lot more money on that. Is there something anyone would like to recommend? I’m looking for the best cannabis vaporizer under $200 I would say. It would be greatly appreciated, thank you very much in advance!

    I like my Utillian 421 vape thanks for the fast shipping and this guide helps. Whats the best temperature to vape weed at though? I get small bit of smoke from my vape and want bigger clouds. Someone on Reddit said I should upgrade to a bigger vaporizer and I think it was a boundless?

    1. Avatar for Tools420 Tools420 says:

      If you’re looking for bigger clouds then try using it at higher temp. settings 220-230 degrees Celsius. The Boundless CFX or the Tera are more powerful and can produce thicker clouds. If you’re looking for something that is small and packs a punch I recommend the Zeus ARC.

    I’d also like to throw my $0.02 in with my Utillian 421 review. I think it’s a good starter weed vape but after a few months I found it worth it to upgrade to a different herb vaporizer (The Arizer Air). Maybe I’d suggest getting a more expensive weed vaporizer to start off.

  6. Avatar for Steven S. Steven S. says:

    Is this a good first weed vape for first timers? I don’t really smoke weed yet but I used a friends herb vape and want to get one. Is it worth it to get a more expensive vape or would this be good enough? I’m 24 and like to use sativa cannabis vaporized because I feel more uplifted.

    Anyone know how the Utillian 421 vs Utillian 420 compares? I bought the Utillian 420 and was thinking of upgrading to this vape tho.

    1. Avatar for Tools420 Tools420 says:

      The 421 has a bigger battery, 2 extra temperature settings and an airflow valve at the bottom of the unit. We actually did a comparison review getting into specifics Utillian 420 vs 421 Review
