"I would definitely recommend these units for those starting out as even though they aren't giant in holding capacity, they are of excellent quality, give great Vape/taste. I wouldn't be going too big until you get the hang of things. If they burn out,then they are cheap enough and you don't waste so much precious juice. Just make sure to keep checking and dripping. A great starting point for the new Vapers to get results and also IMO should be kept handy as a back up if you decide to go for more fancy stuff. I still like'em ;)"
