Vape Factory

I know everyone has their own problems, but my first choice, Eleaf, is not only famous, but also has very few failures, many stores carry them, and I think the pricing is quite accurate, so I recommend it especially for those who are just starting out and don’t know what to buy.
How to choose
Famous e-cigarette manufacturers
I think it is better to choose a famous manufacturer.
Many vape manufacturers are from overseas, and many of them are quite crude, but if you choose a famous manufacturer, you can be sure that you will not find anything that bad.
If you know how to use it well, it’s fine, but many instructions are not easy to understand, but if someone introduces it on the Internet, you don’t need an instruction manual.
Voltage adjustment
If you can adjust the voltage, you can make the smoke the way you like it.
Some manufacturers have a voltage adjustment function in almost all of their models, so even if you buy an inexpensive model, you may not be disappointed.
I choose a model from a manufacturer that has the functions I want.
Price
Cheap manufacturers are very cheap, and expensive ones are very expensive.
Cheap ones are not all bad, but there are many lousy ones.
I have the impression that many well-known makers have good products even if they are inexpensive.
On the other hand, there are some models and manufacturers that I don’t understand why they are so expensive.
It is not an excuse if they are expensive.
Ease of purchase
Recently, you can buy e-cigarettes at Don Quijote and convenience stores, but I think the number is still small.
I often buy on the Internet, such as Rakuten, but sometimes I cannot find the vape manufacturer I want to buy anywhere, but I think the best thing is to have no trouble, so I think it is better to buy something that is sold everywhere.
Manufacturers that are less prone to breakdowns or malfunctioning parts are easy to get.
My main product has never broken down in 7 years, but it still breaks down when it breaks down.
There are some manufacturers that I think have fewer breakdowns than others, and there are also some manufacturers that I have an image of that break easily, but the manufacturers that have many parts that are easy to buy and replaceable for repairing broken parts are probably the most famous manufacturers.
