I cant make up my mind whether to try the Boges or CE2s,I vape at 6v. and I'm a little frustrated at how short the life spand of the attys.I have tried many different ones from different vender's but they are all the same when it comes to life spand.So I'm tempted to try cartomisers since Rob has the best prices you will find on the web not to mention the best customer service in the business.
