The Twist Slim pen is one of the top vapes on sale from Ooze. It is a small device with all of the essential functions needed to have a positive vaping experience, including 15 second preheating mode and compatibility with 510 cartridges. The vape pen also has one of the best on the market Slim Twist battery.

This vape is made for people who want an affordable device that can be depended on to handle a wide range of vape cartridges.

Ooze Twist Slim Pen Vape Experience Review

The Twist Slim is a tad more expensive than the original Slim, selling for almost twenty dollars, but the extra money spent on this pen is worth it.

  • The Slim comes equipped with a decent Ooze battery that allows for more vaping time and a very efficient USB smart charger.
  • It also has a preheating mode, which is suitable for vaping thick oils.
  • It handles most cartridges pretty well, providing steady output as long as the battery is charged.

Vapor Production

This pen produces very high amounts of vapor for something so small, even on its lowest voltage setting. The clouds get even larger the higher up the user goes on the voltage.

Vapor production varies, depending on the kind of juice, but it is excellent overall. This is thanks to the battery and its steady stream of output.

Power Modes

There are no power modes on this vape except for the adjustable voltage dial at the bottom. The power starts at 3.3 volts and goes to 4.8 volts. Adjustments are made by clicking the firing button on the battery.

The Differences Between the Slim Twist Pen, Slim Twist Pro, and the Ooze Fusion Vaporizer Kit

The Slim Twist Pro has a few extra features that put it above the Slim Twist.

  1. First, it has the ability to vape concentrates. It also has more in the starter kit, including three dual quartz wax atomizers and a silicone dab tool.
  2. But, they cost up to forty dollars; however, considering the extra features, the twenty dollars extra are worth it.
  3. The Ooze Fusion pen is designed for vaping concentrates, and it is very affordable at around fifty dollars. It has a powerful 650 mah battery, and it has three voltage settings: 3.6, 3.9, and 4.2 volts.
  4. Another advantage is that the battery can last for several days, and it takes two hours to charge.
  5. Additionally, the starter kit is fully packed, coming with a smart USB charger, a dab tool, and three different coils. There is even a silicone jar for storing concentrates. The kit is effortless to use, making it ideal for novice vapers.

Ooze Slim Twist Pen Starter Kit

Ooze Pen Starter Kit

The Slim does not come with much, only the pen and the USB plug. Customers have to buy cartridges and pods separately, but these accessories are widely available and sell at varying prices.

Internal Building Quality and Design

The build and design quality are very good for a pen of such size. The threading on the battery is well made, so there should be no problems with cross-threading.

Still, screw it onto the battery carefully to avoid problems. The connection between the battery and cartridge is solid, and there have been no connectivity issues.

Slim Pen Twist Battery

This Twist pen uses a 320 mah battery, which is sufficient for a device of this size. It should last most of the day if used in moderate settings. Slim Twist battery helps to cope with the hit.
The user can choose a precise voltage between 3.3V-4.8V to find the best clouds and flavor.

A USB plug for charging comes with the package for charging the battery. The USB smart charger has overcharge protection that extends the overall life of the battery.

Ooze Pen Battery USB

The only thing a new user needs to be aware of is that the device needs to be recharged on a USB wall smart charger. Non-Ooze chargers can decrease the battery life. It is inadvisable to plug the Slim Pen Twist battery into a computer.

LED Battery Indicator

The charging light is on the USB smarter charger.

  • It shines red when charging, and it turns green when fully charged.
  • Another light is in the form of a ring around the firing button on the battery. It glows green during use or when charging the battery.
  • If the battery needs to be charged, the light flashes green fifteen times.
  • For connectivity problems, it shines four times.

What Cartridges Work with the Ooze Twist Pen?

The Ooze Twist battery is 510 threaded so that it can work with nearly any kind of cartridge. This connection allows the user to vape nicotine and oil cartridges, including denser oils thanks to the preheating feature. The cartridges can be disposable or refillable, depending on the owner’s preference.

What Are Ooze Pens For?

Ooze Twist pens are for vaping nicotine liquids and THC/CBD oils. Rigs and box mods are the best pieces of equipment for vaping THC, CBD, and nicotine liquids, but pens are more portable and less expensive.

They also produce less vapor than rigs and mods, making them ideal for people who want to vape discreetly. Ooze pens like the Fusion and Ooze Twist Pro can be used for dabbing concentrates.

How to Use the Ooze Twist Slim Pen

The Twist Slim battery is easy to use, and it can be figured out in less than a minute.

  1. The first thing to do is choose a cartridge, fill it if necessary, and screw it into the connection in place of the USB smart charger.
  2. With the cartridge in, click the power button five times in succession to start vaping.

The voltage on the battery is adjusted by turning the knob at the bottom.

  1. Start on the lowest voltage setting first, and then gradually increase it until the most comfortable setting is found. Thicker oils may require the use of the pen’s preheating feature.
  2. Activate it by clicking the firing button twice.
  3. Click it once to exit preheating mode.

How to Refill Ooze Slim Pen

Whether a cartridge has to be refilled depends on if it is refillable or not. Non-refillable cartridges can be thrown away when depleted.

For refillable cartridges, unscrew the mouthpiece, pour the liquid inside, and avoid pouring it into the chimney. When filled, screw the mouthpiece back on.

Ooze Twist Slim Pen instructions

  • Screw in the 510 cartridge.
  • Click the firing button on the battery five times to turn on/off.
  • The battery will heat while holding the button for 15 seconds.
  • Click the button twice to activate the continuous heating.
  • One click will deactivate the preheat.
  • Adjust the battery voltage by rotating the dial at the bottom.

Alternative Products to the Ooze Pen

Ooze Twist Slim Pen vs. Frio Twist Vape Pen

Frio Twist Starter KIt

The Frio Twist is a very good vape pen as well, and it is available at nearly the same price. The most significant difference between these vapes is that the Frio Twist comes with a much more powerful 1,100 mah battery that lasts significantly longer than the Ooze Twist Slim’s 320 mah battery.

Ooze Twist Slim Pen vs. Puff Buddi Twist

Puff Buddi Colors

The Ooze and Puff Buddi are almost identical when looking at the specifications. They have similar voltage settings, preheating modes, and the same battery.

Both pens are also 510 threaded. The only difference is that the Puff Buddi is a few dollars cheaper than the Ooze.

Frequently Asked Questions About This Ooze Pen

  • How to Use the Twist Slim Pen in Preheat Mode

    Preheating is best used for thicker oils so that they are vaporized more effectively. While using wax it is needed to increase the temperature a few notches before preheating

  • How to Clean a Twist Slim Pen?

    The only part of the Slim that needs to be cleaned is the connection. Ensure there is no liquid on it, and occasionally wipe it down with a damp cloth. A dirty connection can affect the vaping experience, so be sure it remains clean.

  • Why is My Twist Slim Pen Blinking Green?

    • When the vaporizer battery is depleted, the green light will flash fifteen times 15 times. Charge it at this point.
    • If the battery flashes four times, there is a connectivity issue. Most likely, the cartridge was not screwed in all the way or is cross-threaded.
    • Try unscrewing the cartridge and screwing it back on. If this does not work, contact Ooze and ask them for advice.
  • Is Ooze a Good Brand?

    Ooze has gotten a lot of positive attention, and they are ideal for people who want reasonably affordable devices that do a good job vaporizing nicotine liquids, oils, and concentrates. They take care of producing high-quality vaping gear for almost 15 years.

Final Thoughts This Ooze Twist Device

There is not much to complain about when vaping these pens. They are designed for vaping oils and nicotine liquids and nothing else. Also, they are easy to use and do not require a lot of time to figure out.

The fact that they are dual compatible with nicotine juice and oils is a major advantage. The only complaint is that the battery light does not have different colors to indicate how much life is left. Overall, though, this is an excellent vape that is worth the money.

I love the written word, and in my career as a journalist, I strive to provide the facts about everything I write about. There are too many false and alarmist stories out there about life and vaping mainly. My mission is to make e-cigarettes less scary to people with informative articles and extensive research on not only the possible evils of cigarettes and Big Tobacco, but the objective side of e-cigs.

    Worst Vap pen on the market. My first one lasted a week. The second one lasted 3 DAYS!! Customer Service does not care. So save your money, but another brand.
