1. Oil Intake Hole Size - What Does It Mean and Why is it Important?
If you have ever purchased a vaporizer cartridge, you may have asked yourself 'What are those little holes on the inside of the cartridge?" Well, don't worry, because you are not alone. Turns out, most users have no idea what those holes are for. They vary in size 2.0mm, 1.6mm, 1.2mm, 0.9mm.  these holes are actually one of the most important aspects of a cartridge, and can determine how well your product will pull when inhaling.
when it comes to determining the right Oil Intake Hole Size is quite simple: "The Thicker the Oil, The Bigger the Hole."  If the oil that you are wanting to fill the cartridges with has a very thin consistency, then 0.9 mm Oil Intake Hole Size might be the best route. But if the consistency of the oil is really thick, then you might want to look into the 1.6 mm or 2.0mm cartridge.

The best way to check which oil intake hole is right for you is by testing out each hole size first. It's very important that you have the right hole size for your oil, because not only will it affect the amount which you are inhaling, but hole sizes that are too big or too small for your oil can cause leaks in the cartridge.

So the next time you decide that you need a new vaporizer cartridge, make sure you know exactly what it is you are looking for first, and if you are not sure, please contact us.

2.THE ADVANTAGE OF CERAMIC COIL VAPORIZER CARTRIDGE
 
1).NO BURNT TASTE FROM DRY HITS
 A related benefit of ceramic coils is that they reduce the chance of getting the unpleasant taste that usually accompanies a dry hit. You won't burn your cotton, and so the gross taste of singed wick material becomes a thing of the past.

 2).NO SPITBACK
 Ceramic coils also reduce the chance of spitback, because any e-liquid that does spit out of the coil has to make its way through the ceramic before it could get to your mouth. The small pores in ceramics also make it difficult for juice to pool up around your coil, which is one of the biggest causes of spitback.

 3).IMPROVED FLAVOR
 there is an improvement in flavor from using ceramic coils. From experience, it certainly does give a very clean flavor and there is nothing in a ceramic coil that will react or otherwise interfere with the flavor of your e-liquid. The increased surface area stemming from the porous ceramic material should also mean more juice is vaporized with each puff, which also contributes to flavor.
