e-cig e-liq Batteries are junk Internet

The company sells e cigarette products.  The batteries it sells, the e-cig ego, batteries are total junk.  They are cheaply made, and are press fitted together between the battery housing and the fitting on the end where the cartridge screws in.  Sometimes when unscrewing the cartridge the fitting comes out of  the pressed housing, or if you drop the battery the end piece will pop out.  They are nearly impossible to put back together and the little wires between the housing and battery to the switch break rendering the battery useless.  I have complained numerous times to the company about the defective design in this but they only nod their head but do nothing to make any improvements.  They are suppose to be chargeable up to 500 times, (they do last almost all day) so that would be 500 charges which would be about a year and a half at least, but they only warranty them for 30 days.  that's because these units won't stay together and break, not because the battery goes bad.  I wouldn't know if they would take 500 charges as claimed, I've never had one that stayed together more than 60 days to find out.  At 17 to 24 dollars a pop, I am not going to buy anymore of their garbage.  Back in the 60's and 70's Chinese imports were notoriously know for their cheap made junk, but they finally cleaned up their act, but with this product they have back slid 40 years or better.
