Ok the only divice I have is the DSE901 and it has not been enough to help me totally quit smoking the batteries just do not last long enough and it does not put out enough vapor or give enough throat and lung hit. So I was just curious what you guys think of these devices? I want goood battery life and lots of vapor but it also has to be a low matinance divice since I dont want to have to spend all my time cleaning the thing so basically need something idiot prof. Help please.
