Oh yeah this is always interesting! Will lighten your wallet too!
They really hit the spot. By the end of the first month many have bought another model to try. (I bought 2 more in the first month but yay I am still using those 2).
Grats on your new adventure! Drink plenty of fluids - vaping can be drying. If your mouth/throat or lungs get sore that is usually nicotine in 100% PG liquid. PG lets through the flavor and nicotine's TH best but also nicotine's skin irritation the best. You may want to order one VG juice in case you need to cut PG juices. I usually vape 80PG/20VG. VG dulls everything PG lets through but adds thicker visible vapor. You can also cut PG juices with plain 100% vegetable glycerin (I know Wilton who makes cake decorating supplies sells a small bottle, and a health food store might - just make sure it is 100%). If you add plain VG to a juice it will cut the nicotine and the flavor.
It doesn't hurt to take vitamins for a few days as your body loses the 4000 chemicals in cigs. I felt a bit off for a few days but nothing bad.
Be aware of the common symptoms of too much nicotine - headache, blood pressure changes, rapid or irregular heartbeat, cold fingertips, lightheaded or ill feeling. When I started I left my ecig in another room where I used to smoke and tried to vape about the same amount I smoked. I still leave them in another room at home just so I don't vape constantly but now I vape more often and though sometimes for fewer drags.
