“This is really good, I've vaped for over 15 years now and have tried numerous vapes and I can definitely vouch for this one, it's strong and smooth, you can also purchase a larger glass that fits it perfectly which is far better than the 2ml tank it comes with as it hold 5+ mls saving you constantly filling, however saying this it's also a reasonable amount of liquid you can get in the tank if your happy with 2ml”
