I had the opportunity to try an iClear30 recently when altsmoke had them back in stock, i was shopping for a kick so said what the heck and snagged an iclear30 with a replacement head for 2 bucks. First impressions, it kicks vivi novas .... to kingdom come, folks. No leaking, no wicking issues but again it varies on the juice u use. And I repeat, these are just my first impressions, when it comes time to clean them and disassemble a few times, we shall see if it rocks or not. But for now, if you wanna vivi nova that perfirms better and isnt so freaking delicate, then go with an iClear30. I'm sorry but the drip tip thing isnt a deal-breaker imo, I sorta think it's neat but I wouldn't want it on anything else.
