Straight to the matter at hand... I have an eGo-T and its worked pretty well for me and I do like it. The big complaint I have right now is that it gets really harsh to take a hit if you fill it up, smoke it half way down (over like a day) and at that point the fluid changes to a dark color from clear as well. Some times I refill it even though the liquid is starting to change color. Doesn't work so well, its still harsh as it was with more fresh fluid. Well what I do when this happens is I dump the discolored remaining liquid out, take it apart, clean the wick coil system by running it under water and drying. Put it all back together, fill her up and she is back to normal. Now I hate to waste vapor liquid like that by dumping it out, but its basically unsmokeable stuff. Why is this happening? Do I need to clean my Atomizer at this point now to prevent this from happening? Thanks in advance.
