I have a Stiiizy Liquid Diamond All-in-One Disposable Pod THC pen that I think may have been given to me by a friend or recommended to me by someone who liked its sleek, modern design and wanted me to try it. Honestly, the first time I took it out of the box I thought it looked like a futuristic gadget from another world and not something I would associate with marijuana.

However, having gone through many pods since I started using mine, I consider the Stiiizy to be the iPhone of vape pens – and I mean this in a good way – easy-to-use, reliable, and a great introduction to vaping for new users. Unlike a lot of guides that simply lay out step-by-step instructions, this article provides the guidance and insight that I wish I had available to me right off the bat.
First, Meet Your Device
Take everything out of the box. You will find the battery (the power source, which looks like a rectangular stick), and the pod (a refillable cartridge that contains golden Liquid Diamond oil).

- The Battery: This is the heart of the system. The Stiiizy pen does not have any buttons; instead, it uses a draw activation mechanism, which means you simply inhale to create a vapor stream. Easy enough. On the top of the battery is a magnetized connector, where you attach your pod, and at the bottom is a USB-C charging port.
- The Pod: This is the fuel. I have found the Liquid Diamond oil, made by Stiiizy, to be superior to their regular distillate oil. For me, the high produced by the Liquid Diamond oil is clearly stronger and has a more complex flavor profile and smooths out quickly, and comes on slowly (has a creeping quality).
From Box to High: Step-by-Step Instructions
1. Charging Time.
Charge the battery before doing anything else. A weak battery is unable to vaporize the oil properly, resulting in poor hits, clogs in the pod and a disappointing user experience.

- My Experience: I use a phone charger block with a USB-C cable to charge my battery. A full charge takes approximately 30-45 minutes and once charged, the light on the battery turns from red to blue. When I'm low on battery, I charge it as soon as the light begins to flash red while I'm mid-hit (this indicates a low battery signal).
2. Connect the Pods Using Magnets
I am impressed with how well Stiiizy designed this aspect of their product. Simply press the pod into the magnetic connection on top of the battery and you'll hear a 'click' and feel the pod secure itself onto the battery. Do not force it, the magnets help position the pod correctly.

- My Tip: Keep the area around the magnetic connector spot clean. A small piece of pocket lint can prevent a solid connection. Wipe the area with a cotton swab to keep it clear.
3. The Inhale Technique: Sip, Don't Chug
It's very tempting to take a huge, deep drag off a vape pen. However, avoid it.
Put your lips on the mouthpiece and take a slow, gentle and steady pull of the vapor for 2-4 seconds. Think of taking a slow drink from a straw while drinking a thick milk shake.

The oil is very potent. Taking a small sip allows you to control the amount of oil you get, and you'll know how much THC you've taken. Additionally, if you take a large pull, the vape pen could overheat and burn the Liquid Diamond oil prematurely.
Mistake I Made: My first hit was extremely long and hard. I coughed for 5 minutes and ended up feeling very high and anxious in a matter of minutes. Begin with a small sip. You can always take another sip, but you cannot take less.
4. Hold It? Or Not?
There is an old myth that if you want to maximize your THC absorption, you should hold the vapor in your lungs for a certain length of time. This is not required. Once you have taken a breath of vapor, I simply hold it for 2-3 seconds to allow the vapor to dissipate, and then exhale naturally. Most of the cannabinoids are absorbed immediately.
5. Be Patient And Pay Attention To The Vape Pen
Do not attempt to take another hit for at least 10-15 minutes after your first small puff. Vapor-based THC products produce a quicker onset than edible products (typically within 5 minutes) but the effects from the Liquid Diamond oil seem to develop slower and creep up on you. Allow the full development of the high before taking another hit.
Personal Insights & Pro-Tips
- Store Your Device Upright: Store the device vertically at all times. If you leave it lying down (especially in a hot location) the oil can drip into the airway, creating a clog in the device, which can be frustrating and waste valuable oil.
- Fix Clog: If you feel resistance when you try to breathe in, you probably have a clog. Panic and try to inhale harder. Instead, follow these steps: Remove the pod from the battery and put your lips on the mouthpiece of the pod and give a short, powerful exhalation into the mouthpiece. You will usually hear a distinct "pop" as the clog clears. Another method to clear clogs is to lightly preheat the oil by placing the pod in the palm of your hand and rubbing it back and forth for 30 seconds.
- Tolerance & Quality Of Liquid Diamond Oil: If you have previously used other vapes, be aware of what you are getting yourself into. The Liquid Diamond oil is significantly more potent and complex compared to other distillates. The high appears to be smoother, cleaner and less "high-strung" to me but it is undoubtedly strong. Treat it with respect.
- Social Aspect: The Stiiizy is a great social vape due to how easy it is to share with others without needing to explain the operation. Just remind them to "sip" and teach them your technique.
Final Perspective
The Stiiizy Liquid Diamond pen became my go-to vape device due to its dependability and quality. I recommend it to my curious friends because it makes the entire cannabis experience much easier. It's compact, efficient, and produces a premium-quality effect that, for me, warrants the slightly higher cost of the Liquid Diamond oil.
