I received my first 801 attys and carts today so I made my second nicostick. The first one I did was a 510 as that is the only model I have ever used. I'm not going to post a picture because it looks like every other one built. At first I thought my atty was bad until I added several more drops of liquid to get it going. It is amazing to me how different the 801 vapes compared to the 510 when both are using the same battery. I am really starting to like the 801 alot. I would like to build one more at 5v but I haven't found a switch that I can fit in a two battery box with regulator and the atty attached on the outside. I really don't want to but I may give in and get a three battery box just so I can try the 801 at 5v.
