this is a review for the CE5 aspire bbc I got from DV,IMO they are a pice of junk,the frist coil that came with the unit worked only for one tank full,than give little or no vapor,so I changed to a new head,this was worse so changed heads again still the same thing, than I used the second ce5 that I got same thing with this unit,this , every body else raves about this aspire CE5 ,but I have had nothing but problems with it spent 6.95 +2 for the units and 12.95 + 2 for new coils, totalabout 40 bucks and the worst things I have ever gotten.will not be getting any aspires for now , maybe I just got a bad pair of atties and coils ,but will not get bitten again by the same thing , been using the iclear clearomizers and very happy with them,don't get me wrong I don't blame DV for these bad units,just letting people know that the aspire line aren't the best out there, .....dennis,j
