Jo, I googled the Ecigs you mentioned. Not a lot of info there, but I don't know anyone who had those particular models. Most of the folks here on the forum start with the Joye 510, KR8, Ego, and a few others. Check out the New Members Forum for reviews and explanations of what others think of their choice in Ecigs.
Taste grows as you break in an atomizer. It's terrrible at first but gets very nice as you use your Ecig. Your taste buds become more able to enjoy the subtle tastes of Ejuice as you recover your ability to smell and taste. Flavors that didn't impress you at first begin to be really good!
When you feel the urge to revert back to tobacco, try vaping a little heavier, wait a few minutes, and feel the urge to smoke fade away. Some of us quit cold turkey and others (me) have drastically reduced our analog consumption over the first few weeks. I still have an analog after a meal. I've dropped from 40 a day to 5 a day in one month. The future will probably see me quitting completely.
Don't feel like you've failed if you have to have an analog. The Ecig allows you to control the physical urges to smoke, but it takes time to overcome the physical "feel" of smoking and the quick hit of the nicotine from an analog. Think of it as a journey over time. You will soon realize that an analog tastes terrible compared to your Ecig.
There are also some other chemical things going on with tobacco that simple nicotine replacement doesn't satisfy. Read this link for some insight into that ->
This is your brain on nicotine
