As a former user of only kanger product. Evod, protank, etc. I officially switched to innokin. I love the iclear 30. I used it for about two weeks and had the same gurgle issue. Went back to my local shop to buy a 2nd one and they had the 30 s in stock so I bought it. Imo this is way better tank than the 30. Same great taste and vape. No gurgle. Give it a try. Think you'll love it like I do.
