The GeekVape Aegis Hero Pod Kit is best suited to MTL (Mouth to lung) high PG e liquids and is perfectly paired with Nicotine Salt e liquids to offer the best vaping experience. Available in pre-mixed 10ml bottles, Nicotine salt are much smoother on your throat while inhaled, and due to this, most Nic Salts E-Liquids contain a higher level of Nicotine. Nic Salts effect on your body is different; while Pure Base Nicotine gives you a slower and constant Nicotine dose, the first gives you a much faster Nicotine Rush, which your body assimilates at a quicker rate. So, if you are looking to stop smoking, and afraid of Nicotine craving while still wanting a smooth vape, Nic Salts should be your pick, but if you are looking for a harsher throat hit at a lower Nicotine dosage, sticking with Pure Base could be the better option.
