I've only had mine for a few days but I really like the Blu. I almost canceled my order too. The cartridge flavors are really good (loving the Java). The battery life is adequate- when I take it to work, a single battery will last me through the shift (I still go outside because I don't want to push it). My son has been begging me for the Blu in trade for the 510 he originally decided he wanted. Shipping was less than a week. I'm sure that one of these days, I will want a Chuck but for now, I'm happy. It is pretty close to the feeling of smoking an analog.
