So for "beginners" already useful but the mouthpieces to use are not as good as the liquid can pass through to the battery almost, I bought me an extra essay where the liquid is completely separately enclosed and neither leak up nor down " could ". No matter how much one fills Liquid or how firmly or less firmly pulling on the steamer, the Liquid carves it were always a way, otherwise the steamer itself is quite good, and long battery charging does not take too long.
