I have tryed 6 different electronic Cigarettes and the DSE901 is the best I have tryed! There are basically 3 parts the battery, atomizer, and the filter.
The battery last all day for an average pack of a day smoker. The tip is blue instead of red.The charger plugs into standard 110 house current and charges fairly fast (1 to 3 Hours).
The Atomizer is built within a metal tube to protect it to and appears to last a longer time then others I have used. It produces more smoke then any e-cigarette I have used.
The filter is larger then any e-cigarette that I have used which means they last longer. (the filter is where the nicotine and flavor is) They come in high, med, low and no nicotine. They offer many flavors. I have tryed marboro, mint, peach, and pipe tobacco and found them all enjoyable.
The overall e-cigarette is great. It looks more like a pen then a cigarette like many of them do. I would recommend this product for anyone that is quitting smoking. You still get the nicotiine and the sensation of smoking without the harmful side effects!
