blu cigs tanks and cartridges reviewBlu Cigs Cartridges fail to work 90% of the time when buying them from the store. It seems as though when purchasing Blu Cartridges online they seem to have a better performance rating than buying them from the store. However, if you have owned a Blu Rechargeable for any length of time, you know how terrible it is to buy a new 5 pack of cartridges only to have them not work as they should. Often times consumers blame their Blu batteries, (which can in fact be the problem) but in many cases it’s the actual Blu cartridges that fail to work. It remains to be seen as to why this is the case, we’re thinking that it’s got something to do with the storage of the cartridges.
