Here are some important factors to consider when choosing an atomizer:

• Type of atomizer: consider different types of atomizers (tanks, sub-ohm, RDA, etc.) and choose the one that best suits your needs.
• Number of coils: atomizers come with one, two, or more coils. If you want more vapor, it's better to choose an atomizer with multiple coils.
• Capacity: choose an atomizer with a capacity that fits your needs. If you use your atomizer outside the home, you may need a larger atomizer with a bigger liquid reservoir.
• Coil and atomizer type: some atomizers use replaceable coils, while others use a coil that needs to be replaced by yourself. Think about which type would be more convenient for you.
• Draw: there are two main draw types to start with when choosing an atomizer. MTL - cigarette-like, tight draw. Suitable for people who do not require a large amount of vapor and are interested in using it only as a cigarette-like alternative. DL - hookah-like, free draw, which allows you to get more flavor and vapor.
• Airflow: airflow can significantly affect the taste and amount of vapor you get. Therefore, pay attention to the airflow holes and adjustable airflow in the atomizer.
• Flavor reproduction: some atomizers can more accurately convey the taste of the liquid, usually depending on the mouthpiece, amount of air, length and width of the shaft, and temperature of the inhaled vapor. The combination of these parameters can affect flavor transmission.
• Brand: choose a brand that meets your requirements for quality and reliability.
• Price: atomizer prices can vary significantly. It is not worth saving on quality, but you also do not need to pay more than you are willing to. Find an atomizer that meets your needs and budget.

Rebuildable atomizers are atomizers that can be assembled and serviced by the user. They usually have a deck with posts for attaching coils and cotton, which is used for liquid saturation.

Advantages of rebuildable atomizers:

1. Customizability: you can customize the atomizer to your taste by installing the desired coil and adjusting the amount of cotton, which provides a more individual approach to vaping.
2. Economy: rebuildable atomizers can be more economical than disposable atomizers because you can change the coils and cotton yourself instead of buying new cartridges or replacement coils.
3. Ability to vape at higher power: rebuildable atomizers typically allow vaping at higher power than disposable coils, which can provide a richer taste and denser vapor.

Disadvantages of rebuildable atomizers:

1. Complexity: assembling and servicing atomizers can be more complex than using disposable coils.
2. Experience required: assembling and servicing atomizers requires certain experience to install the right coil, choose the right amount of cotton and adjust the atomizer for optimal vaping.
3. Risk of leaks: if the atomizer is not assembled correctly, liquid leaks may occur.

Non-rebuildable atomizers have their own advantages and disadvantages compared to rebuildable atomizers.

Advantages of non-rebuildable atomizers:

1. Ease of use: there is no need to rebuild or replace the coil or wick, simply replace the used replacement coil with a new one.
2. More accessible for beginners: non-rebuildable atomizers do not require knowledge in electronics and safety, making them more accessible for beginners.

Disadvantages of non-rebuildable atomizers:

1. Need to purchase new replacement coils: the constant need to replace coils can become expensive.
2. Limited selection: there is a limited selection of different types of coils, which may not meet the user's personal preferences.
3. Possible leaking: since coils do not always seal tightly, there may be a risk of liquid leakage.
4. No adjustability: the user cannot adjust the parameters of non-rebuildable coils, such as resistance and power, according to their needs, which can limit their ability to achieve optimal taste and vapor production.
